grsync for centos 7
by Francis Gerund 09 Mar '15

09 Mar '15

Hello. I think it is just too easy to make mistakes with rsync. And getting it "almost correct" can really get you hurt. So I would like to learn with Grsync. But, Grsync does not seem to be in the centos 7 or EPEL 7 repositories (although it may have been around as late as centos 6). Is it now in any "reputable" repositories? If not, has anyone installed it from source code, and if so, did it work okay?

Centos 6 - disabling IPv6 addressing
by Robert Moskowitz 09 Mar '15

09 Mar '15

I have just moved a host from a network that supports static IPv4 and IPv6. The IPv4 addr is set in ifcfg-eth0, and the IPv6 via RA (I set the MAC so I get an IPv6 addr that I like). I just moved the host to a network that supports static IPv4, but only dymanic IPv6, so at this time (until I get static IPv6), I need to disable the global IPv6 addressing. So in the ifcfg-eth0 file I set: IPV6INIT="no" But I am still getting a global IPv6 (and of course local scope). What else do I need to do to disable the listening for RA announcements and setting an IPv6 global address? I do not want to reboot the box. I can restart the network as needed. I seem to recall, once upon atime an option in /etc/sysconfig/network thanks

Fail2Ban Centos 7 is there a trick to making it work?
by John Plemons 09 Mar '15

09 Mar '15

Been working on fail2ban, and trying to make it work with plain Jane install of Centos 7 Machine is a HP running 2 Quad core Xeons, 16 gig or ram and 1 plus TB of disk space. Very generic and vanilla. Current available epel repo version is fail2ban-0.9.1 Looking at the log file, fail2ban starts and stops fine, there isn't output though showing any login attempts being restricted. 2015-03-09 12:54:37,930 fail2ban.server [14805]: INFO Stopping all jails 2015-03-09 12:54:37,931 fail2ban.server [14805]: INFO Exiting Fail2ban 2015-03-09 12:54:38,338 fail2ban.server [16678]: INFO Changed logging target to /var/log/fail2ban.log for Fail2ban v0.9.1 2015-03-09 12:54:38,341 fail2ban.database [16678]: INFO Connected to fail2ban persistent database '/var/lib/fail2ban/fail2ban.sqlite3' I copied jail.conf and added the edited jail.local to the directory /etc/fail2ban/ This is about as far as I have gotten with searches on how to configure with Centos 7. Any help would be welcome. What am I missing? john

mod_clamav, apache and centos6?
by James Pearson 09 Mar '15

09 Mar '15

I'm trying to get mod_clamav working with Apache on a CentOS 6.6 box - without much luck ... I'm using httpd 2.2.15-39.el6.centos.x86_64 with clamav 0.98.6-1.el6.x86_64 (from EPEL) and mod_clamav 0.23 compiled from source via http://software.othello.ch/mod_clamav/ The mod_clamav source hasn't been updated in nearly 6 years - so may well no longer work with more recent versions of Apache or Clamav ... Before I spend too much time on this - I was wondering if anyone has this set up working, or should I give up and try something else? Thanks James Pearson

LVM encryption and new volume group
by Tim 09 Mar '15

09 Mar '15

Hello list, I bought a Thinkpad T420 and installed CentOS 7 recently. I choosed to use lvm encryption for the entire volume group. It works so far. But now I am planning to install a second hard disk. My thought is to create a new volume group on this additional disk. But how can I integrate/do this according to the existing encryption so that it will be decrypted by the same passphrase I use at startup? Regards and thanks in advance Tim

mariadb driver for named-sdb (CentOS 7)
by Jim Holmes 08 Mar '15

08 Mar '15

I've looked high and low and I cannot a package that has the mariadb driver to go with bind-sdb-9.9.4-14.el7_0.1.x86_64. Everything I'm finding is how to build from source, which for this project will not be maintainable. Is there a yum repo with this driver anywhere? Thanks much, Jim

Squid on CentOS 7: few questions
by Niki Kovacs 07 Mar '15

07 Mar '15

Hi, I recently migrated my office's server from Slackware64 14.1 to CentOS 7. Right now I'm in the process of configuring the Squid web proxy. I edited the default /etc/squid/squid.conf, and here's what I have so far: --8<-------------------------------------------------- # /etc/squid/squid.conf # Nom d'hôte du serveur Squid visible_hostname amandine.microlinux.lan # Définitions acl localnet src 192.168.2.0/24 # RFC1918 possible internal network acl SSL_ports port 443 acl Safe_ports port 80 # http acl Safe_ports port 21 # ftp acl Safe_ports port 443 # https acl Safe_ports port 70 # gopher acl Safe_ports port 210 # wais acl Safe_ports port 1025-65535 # unregistered ports acl Safe_ports port 280 # http-mgmt acl Safe_ports port 488 # gss-http acl Safe_ports port 591 # filemaker acl Safe_ports port 777 # multiling http acl CONNECT method CONNECT # Règles d'accès http_access deny !Safe_ports http_access deny CONNECT !SSL_ports http_access allow localnet # Port du proxy http_port 3128 # Taille du cache dans la RAM cache_mem 256 MB # Vidage système coredump_dir /var/spool/squid # Durée de vie des fichiers sans date d'expiration refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern -i (/cgi-bin/|\?) 0 0% 0 refresh_pattern . 0 --8<-------------------------------------------------- The proxy is working as expected. I have a few questions for fine-tuning though. 1. Squid's main logs are stored in /var/log/squid/access.log. I'd like to setup logfile rotation for that, since it can become quite big. How do you handle this? With Squid's intern 'logfile_rotate' directive or with logrotate? What I'd like to do is rotate this logfile about once a week. 2. Which user is Squid supposed to run as under CentOS? On my Slackware server I had the following: cache_effective_user nobody cache_effective_group nobody What's an orthodox setting for CentOS? 3. The access rules are a bit minimal. Do they seem OK to you for a LAN? Any suggestions?

How to install tp_smapi and acpi_call kernel modules

Hello, I've got a Thinkpad T420 and would like to use full tlp functionality. Therefore I need the kernel module tp_smapi and acpi_call. Have a look right here: http://linrunner.de/en/tlp/docs/tlp-linux-advanced-power-management.html#in… There are only fedora related packages but none for RHEL/CentOS. Should I install that repo and hardcode the mirror to the fc21 repo? Regards Tim

Something like apt-cacher for CentOS/RHEL?
by Niki Kovacs 07 Mar '15

07 Mar '15

Hi, For some time I've fiddled with Debian and Ubuntu LTS. There's one really nice feature for local networks: apt-cacher, a package proxy for APT. My company is in the remote South French countryside, and more often than not, schools and public libraries only have some very limited Internet access with relatively low bandwidth, which can make the updating process very tedious. A package cache comes in very handy in such situation. Do you know if something like this exists for RPM-based distributions?

Sieve Filter: All email not from friendly name?
by Benjamin Smith 06 Mar '15

06 Mar '15

I'm using Dovecot and Sieve under postfix on CentOS 6. Sieve filters are working great for a number of addresses. I'm trying to set up a sieve filter that catches all email NOT from Cron Daemon. Nearly all Admin messages come from "Cron Daemon <username@servername>" so I want a Sieve Filter that will catch all addresses NOT from this address and stick it into a folder under INBOX/ProbablySpam but while other filters seem to work fine, this one does not. My best guess so far: if anyof (not address :all :contains ["From"] "Cron Daemon") { fileinto "INBOX.ProbablySpam"; } ... It passes validation checking in KMail, but seems to catch all inbound messages. What am I missing? Thanks, Ben

xorg--x11-fonts-75dpi vs xorg-x11-fonts-100dpi
by Frank Cox 06 Mar '15

06 Mar '15

What is the difference between xorg-x11-fonts-75dpi and xorg-x11-fonts-100dpi? Under what circumstances would one want to use the 75dpi version versus the 100dpi version? If you have both installed, does the xorg server just pick the one that it considers best based on some criteria? Should you have both installed? Is anything gained by having both installed? As you can see I don't know much about bitmap fonts, but I've just started playing with the XForms library and discovered that Centos 7 doesn't install bitmap fonts any more. -- MELVILLE THEATRE ~ Real D 3D Digital Cinema ~ www.melvilletheatre.com

I just tried my first Centos 7 install. I want to install input methods for Chinese. In the good old days, all I had to do was yum install a blob and I was done. Does anyone have a link or some hints that will help me? I did a search, but the hits just confuse me. thanks, Dave

Bonjour, It seems that freeradius 3.0.1-6.el7 of centOS 7 don't work. When doing very simple authentification (PAP control of ssh login on a switch), I get a segmentation fault when the first accounting packet arrives on the server. Does anyone test succesfully this version of freeradius ?

Todays release includes CentOS Linux 7 iso based install media, Generic Cloud images, Atomic Host and Docker containers. CentOS Linux rolling builds are point in time snapshot media rebuild from original release time, to include all updates pushed to mirror.centos.org's repositories. This includes all security, bugfix, enhancement and general updates for CentOS Linux. Machines installed from this media will have all these updates pre-included and will look no different when compared with machines installed with older media that have been yum updated to the same point in time. All rpm/yum repos remain on mirror.centos.org with no changes in either layout or content. Files marked as 20150228_01 indicate that it includes all content released to mirror.centos.org upto ( and including ) the 28th of Feb 2015. Since there is a need to test these images, the release will always lag few days behind the datestamp ( and therefore content included ) in the release. My aim is to automate as much of this as possible going forward to reduce this time lag as much as possible, however we might not be able to remove the lag completely. Other content formats like containers and vendor specific images will aim to start with the same cycle as the main CentOS Linux media, but might move to a more frequent build and release cycle if needed. Special Interest Groups ( http://wiki.centos.org/SpecialInterestGroup) wanting to do media and installer releases should also consider using the rolling timelines to sync with. - ----------- CentOS Linux distro installer media: File: CentOS-7-x86_64-DVD-20150228_01.iso Sha256sum: 8e1195b922def89f4d5846726f3bb1eaecd8bbfcb7a6e415d54a1ed6260ac21d File: CentOS-7-x86_64-Everything-20150228_01.iso Sha256sum: 09f76128a9d613ebc2ec0c6ad1313e78f0ce349dc669b2714e4e9f694c5c569b File: CentOS-7-x86_64-Minimal-20150228_01.iso Sha256sum: c4da447eba9806d50d8a6369f44d5f847f0da4fd49144e5900227e0ca66ae3b2 Symlinks are provided that will always map to the latest released builds, as follows ( including their current mapping ) http://buildlogs.centos.org/rolling/7/isos/x86_64/CentOS-7-x86_64-DVD.iso - -> CentOS-7-x86_64-DVD-20150228_01.iso http://buildlogs.centos.org/rolling/7/isos/x86_64/CentOS-7-x86_64-Everythin… - -> CentOS-7-x86_64-Everything-20150228_01.iso http://buildlogs.centos.org/rolling/7/isos/x86_64/CentOS-7-x86_64-Minimal.i… - -> CentOS-7-x86_64-Minimal-20150228_01.iso These symlinks are updated to point at the latest tested and released media and make for a good target in automation that requires CentOS Linux media. - ---------- For more information and comments please join us on the centos-devel mailing list ( http://lists.centos.org/ ) Enjoy! - -- Karanbir Singh, Project Lead, The CentOS Project -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.14 (GNU/Linux) iQEcBAEBAgAGBQJU+E2+AAoJEI3Oi2Mx7xbthVgH/21II7Wu00wLUJzU5uZn7xl6 olnu3CtTC0Nq7fm7MiP59PoaLTk1GKe4SaQFJQIuNJYdooH06XvarwiIo34SgOWq MV/7KFRhWER0ZLpvJQIa0+r5WjL7OXuOHZ18FomC3/PqIZZaVwhXSXtFnCGgnirD O6C3Ku6ErlTh4tF5gImw8s0FUkTBOOjfl5lL2jcqoSyXJkggs7CqBoH9LzfK/ddw HeLqCenosk72bIXPMhZsM2JiGK8dujjBftcJ3GtvXOvXoWs3+Rl8fTsaSlHUa37/ brPfSDDaVWcp3sVMPmw7XCgT1s3RSxVKVZM1lHvvwZFNMnEj67mCeQN/XMlMdQU= =5Dnk -----END PGP SIGNATURE----- ------------------------------ _______________________________________________ CentOS-announce mailing list CentOS-announce(a)centos.org http://lists.centos.org/mailman/listinfo/centos-announce End of CentOS-announce Digest, Vol 121, Issue 2 ***********************************************

by Tim Dunphy 05 Mar '15

05 Mar '15

Hey all, There's a website I help run that uses the Cassandra DB as its database. I notice that if I run the web server in SELinux permissive mode, the site works fine. But if I put it into enforcing mode, the site goes down with this error: Warning: require_once(/McFrazier/PhpBinaryCql/CqlClient.php): failed to open stream: Permission denied in /var/www/jf-ref/includes/classes/class.CQL.php on line 2 Fatal error: require_once(): Failed opening required '/McFrazier/PhpBinaryCql/CqlClient.php' (include_path='.:/php/includes') in /var/www/jf-ref/includes/classes/class.CQL.php on line 2 I've tried performing a chcon -R command on both the /McFrazier and the /var/www/jf-ref directories. But there's no change to the site being up. Can I get some opinions on how to get this working under SELinux? Thanks Tim -- GPG me!! gpg --keyserver pool.sks-keyservers.net --recv-keys F186197B

Gnome2 Desktop mute buttons for mic and video
by James B. Byrne 05 Mar '15

05 Mar '15

CentOS-6.6 Does anyone know of an application that would provide a 'mute' buttons for video and audio that could be used from a desktop panel? Ideally this would show the status (muted/cloaked or open mic/recording) of each. Presently, turning audio and video pick-ups off and on is rather cumbersome. And I often forget what state I have left them in. Which occasionally makes for some confusing moments trying to debug a non-existent problem.

"Machine Check Exception: 4 Bank 0: 9000000020000003" when boot CentOS 7, with Intel CPU E3845, and BIOS option "EIST" enable.
by Chaoyong 05 Mar '15

05 Mar '15

My hardware is: CPU: Intel(R) Atom(TM) CPU E3845 @ 1.91GHz and it supports EIST(Enhanced Intel SpeedStep Technology). OS: CentOS 7(kernel-3.10) When I set the BIOS options "CPU configuration >> EIST" to "enable", it appears a kernel panic when the system is starting up. Here is what I am seeing: ...... Fast TSC calibration failed. [Hardware Error] CPU 3: Machine Check Exception: 4 Bank 0: 9000000020000003 ...... Machine check: Invalid. Panic - not syncing. Fatal machine check on current CPU. Rebooting in 30 seconds. By reading the Intel-programming-manual, the MCE means: Machine Check Exception: 4 -- MCG_STATUS_MCIP Bank 0: 9000000020000003 -- 0x9000 -- 1001 0000 0000 0000 -- IA32_MCi_Status MSR register 0x0003 -- 0000 0000 0000 0011 -- External Error, The BINIT# from another processor caused this processor to enter machine check. and seems it is an external bus error. If I DISABLED the BIOS option "EIST", there will be no error or panic. If I change to CentOS 6.5/6.6(kernel 2.6), there will be no error or panic even when "EIST" is ON. So, it should be a bug in kernel source of CentOS 7(kernel-3.10). Ps: kernel source v3.10 from kernel.org is OK Any help would be greatly appreciated. Thanks.

Hey folks, How would I allow a user to connect to an FTP server, upload and download files and delete files as well, if that server is in enforcing mode for SELinux? I'm using proftpd 1.3.5 on CentOS 7. Thank you! Tim -- GPG me!! gpg --keyserver pool.sks-keyservers.net --recv-keys F186197B

Extdata / Extprograms Plugins for Dovecot Pigeonhole?
by E.B. 04 Mar '15

04 Mar '15

Hello, I want to install Dovecot Pigeonhole and use the Extdata and Extprograms plugins. According to the dovecot documentation[1,2], those plugins need to be compiled. So two questions: * Are either of these plugins built into the Pigeonhole that is available in the CentOS 7 extras repo? * Is it possible to use these plugins with Pigeonhole installed from yum? Does the compilation requirement mean that I have to remove not only Pigeonhole, but also Dovecot itself from my system and build everything by hand? :-( PS - Is there another version of Pigeonhole in a repo elsewhere (like EPEL or DAG?) that might have what I want?

Dovecot Pigeonhole version in extras repo?
by E.B. 04 Mar '15

04 Mar '15

Hi, I want to install Dovecot Pigeonhole from the yum Centos extras repo, but "yum info" reports the version number not of the plugin but of dovecot itself. Can anyone say what the Pigeonhole version is currently for the extras repo for CentOS 7?

Memory issue in kernel sctp implementation
by Danny Smit 04 Mar '15

04 Mar '15

Dear all, I'm running into a possible memory issue with the SCTP implementation in CentOS 6, using lksctp-tools. So far I've not seen the problem with other distributions yet. The problem is that whenever a SCTP client connection is initiated to a second host and port at which no SCTP server application is listening The scenario is simple: - call socket() to create a socket. - call sctp_connectx() to establish a connection. The last call is repeated periodically to retry to establish a connection. When looking on the wire using wireshark it shows that an SCTP INIT packet is sent to the second host, which replies with an SCTP ABORT. This is exactly according to the SCTP specification. However it appears ABORT isn't propagated into to application layer that calls sctp_connectx(). Furthermore, because reconnect attempts are made, a steady memory increasement occurs. Looking at /proc/meminfo, the increasement occurs in SUnreclaim, the kernel slab cache. Can you advice if this can be an issue with the SCTP implementation in the kernel? Maybe an issue solved upstream, but not (yet) backported into centos 6? It applies to the following package versions (also to older kernels): - kernel-2.6.32-504.8.1.el6.x86_64 - lksctp-tools-1.0.10-7.el6.x86_64 Regards, Danny Smit

Ignorant question on SSL certs
by Timothy Murphy 04 Mar '15

04 Mar '15

I'm getting endless complaints about my dovecot cert, /etc/pki/dovecot/certs/dovecot.pem which I created years ago following the dovecot instructions. Do I really have to use a separate cert and key for dovecot? Can I not use the "standard" cert in /etc/pki/tls/certs (and key) from CACert.org ? -- Timothy Murphy gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin

Apologies for the late replies

*sigh* There seems to have been a problem with my hosting provider's mailqueues this morning. As in, I called, and told them, and no one had reported it, and I even got an actual trouble ticket.... <g> So, I'm assuming they just figured it out. I sent the one on the cert, and the other, before 11:00 this morning.... Sorry to post-add to the conversation. mark

disk space trouble on ec2 instance
by Tim Dunphy 03 Mar '15

03 Mar '15

Hey all, Ok, so I've been having some trouble for a while with an EC2 instance running CentOS 5.11 with a disk volume reporting 100% usage. Root is on an EBS volume. So I've tried the whole 'du -sk | sort -nr | head -10' routine all around this volume getting rid of files. At first I was getting rid of about 50MB of files. Yet the volume remains at 100% capacity. Thinking that maybe the OS was just not letting go of the inodes for the files on the disk, I attempted rebooting the instance. After logging in again I did a df -h / on the root volume. And look! Still at 100% capcity used. Grrr.... Ok so I then did a du -h on the /var/www directory, which was mounted on the root volume. And saw that it was gobbling up 190MB of disk space. So then I reasoned that I could create an EBS volume, rsync the data there, blow away the contents of /var/www/* and then mount the EBS volume on the /var/www directory. So I went through that exercise and lo and behold. Still at 100% capacity. Rebooted the instance again. Logged in and.. still at 100% capacity. Here's how the volumes are looking now. [root@ops:~] #df -h Filesystem Size Used Avail Use% Mounted on /dev/sda1 9.9G 9.3G 49M 100% / none 312M 0 312M 0% /dev/shm /dev/sdi 148G 116G 25G 83% /backup/tapes /dev/sdh 9.9G 385M 9.0G 5% /backup/tapes/bacula-restores /dev/sdf 9.9G 2.1G 7.4G 22% /var/lib/mysql fuse 256T 0 256T 0% /backup/mysql fuse 256T 0 256T 0% /backup/svn /dev/sdg 197G 377M 187G 1% /var/www There are some really important functions I need this volume to perform that it simply can't because the root volume is at 100% capacity. Like the fact that neither mysql nor my backup program - bacula will even think of starting up and functioning! I'm at a loss to explain how I can delete 190MB worth of data, reboot the instance and still be at 100% usage. I'm at my wits end over this. Can someone please offer some advice on how to solve this problem? Thanks Tim -- GPG me!! gpg --keyserver pool.sks-keyservers.net --recv-keys F186197B

Strange crash after NVidia driver installation from ELRepo
by info＠microlinux.fr 03 Mar '15

03 Mar '15

Hi, I just had the weirdest of system crashed. Here goes. I wanted to install a desktop step by step, as I usually do. First the base system, then the X Window System, then the WindowMaker window manager. Everything went OK, then I installed kmod-nvidia from ELRepo. Yum informed me that the driver conflicted with x11-glamor (something like that), so I removed the corresponding package. While doing all this, the system still defaulted to boot in console mode (meaning multi-user.target and not graphical.target). To test X, I just launched WindowMaker using startx. Anyway, I rebooted, and then... nothing. System refused even to startup, and systemd suggested to me that I open journalctl (which taught me nothing). Right now I've started a Slax LiveCD to backup all my data and reinstall the whole thing from scratch. I don't have the slightest clue as to what could possibly have happened here. The only thing I wonder: could it be that installing the kmod-nvidia driver while booting to a default console (and not graphical) could lead to this weirdness? A previous installation on that machine went OK, but the difference was that the first time, I started with a full GNOME installation right away. Any suggestions? Niki

Amanda Testing RPMs
by Johnny Hughes 03 Mar '15

03 Mar '15

It was noted in CentOS Bug 7795 that the amanda package in CentOS does not have dump or xfsdump support: http://bugs.centos.org/view.php?id=7795 I found that it is also like this upstream and they plan to fix it at some point: https://bugzilla.redhat.com/show_bug.cgi?id=1140321 In the mean time, I have created 2 sets of RPMs .. one with dump support and one with dump and xfsdump support: Dump Only: http://people.centos.org/hughesjr/c7-amanda/dump-only/ Dump and XFSDump: http://people.centos.org/hughesjr/c7-amanda/xfs-support/ If we can get some people who actually use amanda to check these files and feedback into the CentOS Bug (7795 link above), we might help the RHEL team with deciding how to compile the fix (with dump only or dump and xfsdump support). Please feedback to the CentOS-Devel mailing list or bug 7795. NOTE: These RPMs should work, but they are not signed and should be considered testing quality at present .. so not production ready without user testing at this point. Thanks, Johnny Hughes

installing C7 on a laptop with Win7, dual boot
by Fred Smith 03 Mar '15

03 Mar '15

Hi all! I've just installed C7 on my netbook that already contained Win7 (and also Fedora 19, which the C7 is intended to replace). The Fedora installer had found the windows installation and it appeared in the grub menu, and was bootable and worked fine. The C7 installer did not put the windows installation into the grub menu. with some googling I found a page at https://priteshugrankar.wordpress.com/2014/09/12/dual-booting-centos-7-and-… that gives a simple recipe for fixing this problem. basically: cp /boot/grub2/grub.cfg orig.grub.cfg grub2-mkconfig -o /boot/grub2/grub.cfg with (on his system) the second command above producing this output: [root@localhost ~]# grub2-mkconfig -o /boot/grub2/grub.cfg Generating grub configuration file ...

Correct, the grub2-mkconfig command doesn't emit lines about windows, but it puts the above lines into the resulting (grub2/grub.cfg) file - towards the bottom. [You could hand-edit these lines into that file if you want, but having them in the 40_custom file means that they will be included when the grub.cfg file is recreated after a linux kernal update.] When you boot the machine you should see the (windows) "name" entry at the bottom of the list of kernel options. Select it and the machine should boot into windows. Windows does have a couple of partitions -- the main/production bootable one as well as a rescue one. I believe that (hd0,2) is the default location/naming for the production/bootable one. - Richard

X11 fonts question
by Fred Smith 02 Mar '15

02 Mar '15

I'm having trouble figuring out which RPM would contain X11 fonts that go by names containing: "-courier-medium-r-*-18-" "-courier-bold-r-*-18-" "-courier-medium-o-*-18-" in sizes 18 (shown), 14, and 12. so far I can't figure it out. I've looked at the contents of all the xorg-x11-fonts-* packages that "yum list available | grep xorg-x11-fonts" lists. The best I've come up with is a bunch that contain files named "*-courXXXX-*" followed by some uppercase characters whose meaning I don't know (where I show "XXXX" above). Since I seem to be fairly clueless on this topic, I'd welcome any useful advice that any of you can give. thanks! -- ---- Fred Smith -- fredex(a)fcshome.stoneham.ma.us ----------------------------- Show me your ways, O LORD, teach me your paths; Guide me in your truth and teach me, for you are God my Savior, And my hope is in you all day long. -------------------------- Psalm 25:4-5 (NIV) --------------------------------

NFS and inode64
by m.roth＠5-cent.us 02 Mar '15

02 Mar '15

Well, we got it working. However, the issue we're now worried about is users creating files and subdirectories. Do we need to worry, and if so, is there some way to reserve inodes < 32k table, other than creating tens of thousands of dummy files now? We don't want, a year or two down the road, for this system to be running, and suddenly everything's broken, because all lower inodes have been used.

Looking for a life-save LVM Guru
by Khemara Lyn 02 Mar '15

02 Mar '15

Dear All, I am in desperate need for LVM data rescue for my server. I have an VG call vg_hosting consisting of 4 PVs each contained in a separate hard drive (/dev/sda1, /dev/sdb1, /dev/sdc1, and /dev/sdd1). And this LV: lv_home was created to use all the space of the 4 PVs. Right now, the third hard drive is damaged; and therefore the third PV (/dev/sdc1) cannot be accessed anymore. I would like to recover whatever left in the other 3 PVs (/dev/sda1, /dev/sdb1, and /dev/sdd1). I have tried with the following: 1. Removing the broken PV: # vgreduce --force vg_hosting /dev/sdc1 Physical volume "/dev/sdc1" still in use # pvmove /dev/sdc1 No extents available for allocation 2. Replacing the broken PV: I was able to create a new PV and restore the VG Config/meta data: # pvcreate --restorefile ... --uuid ... /dev/sdc1 # vgcfgrestore --file ... vg_hosting However, vgchange would give this error: # vgchange -a y device-mapper: resume ioctl on failed: Invalid argument Unable to resume vg_hosting-lv_home (253:4) 0 logical volume(s) in volume group "vg_hosting" now active Could someone help me please??? I'm in dire need for help to save the data, at least some of it if possible. Regards, Khem

The solution is to: edit: /etc/grub.d/40_custom putting in: menuentry 'name' { insmod ntfs set root=(hd0,2) chainloader +1 } note: "name" can be anything you want (within reason), and is the name that will show in the boot menu. the values here: root=(hd0,2) will vary based on your disk setup. if you still have your fc19 grub/grub2 (whichever it used) configuration file you should be able to confirm the values from that. when done, then: grub2-mkconfig -o <output file> personally, i didn't set the -o to the production grub.cfg file as my preference is to make backups and check things before potentially trashing a file like that, but do as you wish. when you're comfortable with the generated file move it to the production location and reboot. - Richard

scp -rp behavior
by Mark LaPierre 02 Mar '15

02 Mar '15

Hey all, I'm trying to copy configuration files from my old CentOS 6.6 32 bit machine to my new CentOS 6.6 64 bit machine. On my 32 bit machine: [mlapier@mushroom ~]$ ifconfig eth0 Link encap:Ethernet HWaddr 00:19:DB:E5:4E:9F inet addr:192.168.15.105 When I issue this command on my new 64 bit machine, 192.168.15.101: scp -pr mlapier(a)192.168.15.105: /home/mlapier/.thunderbird /home/mlapier/.thunderbird It copies all directories and files in 192.168.15.105: /home/mlapier/ to 192.168.15.101: /home/mlapier. I don't want all that, I just want the .thunderbird folder and all it's contents. The user and group account numbers match on the two machines for this user so that's not the issue. When I RTFM this is what I thought it said to do. I'm I misreading the FM or is something weird going on here? -- _ °v° /(_)\ ^ ^ Mark LaPierre Registered Linux user No #267004 https://linuxcounter.net/ ****

I don't want to underestimate the value of good hardware RAID with BBWC implementations when it comes to avoiding problems that aren't bugs, but are "just the way things are." For example unclean shutdowns, and especially unclean shutdowns along with a device failure. There's a metric ton of really useful information in the man 4 md page that most people probably aren't aware of because they usually read the mdadm page. http://linux.die.net/man/4/md Relevant in this case is the Unclean Shutdown section. It's completely rational for people to think, hmmm, maybe I'd rather get a hardware RAID card that supports BBWC to avoid some of these problems? Plus then you get to use no barriers, resyncs and degraded operation can have much lower performance penalty, etc. -- Chris Murphy

Cyrus 2.4 and Centos6
by Timothy Kesten 28 Feb '15

28 Feb '15

Hi Folks, I'd like to install cyrus-imapd 2.4 in CentOS6. Found rpm cyrus 2.4 for CentOS6 on rpmseek. cyrus-imapd-2.4.17-30.1.x86_64.rpm But there are conflicts with postfix 2.6.6. Can I ignore this conflicts or is there a suitable version of ppstfix available? Thx Timothy

Odd nfs mount problem
by m.roth＠5-cent.us 28 Feb '15

28 Feb '15

I'm exporting a directory, firewall's open on both machines (one CentOS 6.6, the other RHEL 6.6), it automounts on the exporting machine, but the other server, not so much. ls /mountpoint/directory eventually times out (directory being the NFS mount). mount -t nfs server:/location/being/exported /mnt works... but an immediate ls /mnt gives me stale file handle. The twist on this: the directory being exported is on an xfs filesystem... one that's 33TB (it's an external RAID 6 appliance). Any ideas? mark

OT: AF 4k sector drives with 512 emulation
by Robert Arkiletian 28 Feb '15

28 Feb '15

Still have good quality older sata hardware raid cards that require 512 bytes/sector. As far as I know HD manufacturers are not making native 512 bytes/sector drives any more. Some have better 512e emulation than others. Looking for some advice on which to avoid and which are recommended. Thanks. PS this is for a CentOS6 server.

yum causing RPC timed out?
by Dave Burns 28 Feb '15

28 Feb '15

I just installed centos 7, yum is acting strange, experiencing RPC time-outs. Sometimes when I disable the additional repos (epel and rpmforge) it seems to make things act normal. But not this time (see below). Could I have some misconfiguration? Network glitch? What hypotheses should I be considering?

Package group "X Window System" has disappeared
by Niki Kovacs 27 Feb '15

27 Feb '15

Hi, Until last week, I could install a CentOS 7 based desktop using the following approach: 1. Install minimal system. 2. yum groupinstall "X Window System" 3. yum install gdm gnome-classic-session gnome-terminal liberation-fonts 4. Install applications as needed. This morning, the package group "X Window System" seems to have disappeared. This is embarrassing. What happened?

CentOS 7 hand-edit the network configuration files
by Helmut Drodofsky 27 Feb '15

27 Feb '15

Helo, on http://wiki.centos.org/FAQ/CentOS7 in 3. And what if I want the old naming back? is written: /etc/udev/rules.d/60-net.rules seems necessary to override /usr/lib/udev/rules.d/60-net.rules According to my experience, the text should be changed to: /etc/udev/rules.d/70-persistent-net.rules has to describe the naming rule according to this example: SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:00:00:00:00:00", ATTR{type}=="1", KERNEL=="eth0", NAME="eth0" where ATTR{adress} is the HWADDR of the network interface. Static assignment: GATEWAY has to be configured in /etc/sysconfig/network -- Viele Grüße Helmut Drodofsky Internet XS Service GmbH Heßbrühlstraße 15 70565 Stuttgart Geschäftsführung Dr.-Ing.

repositories
by Pol Hallen 27 Feb '15

27 Feb '15

Hi all :-) This is my first post: I'm coming from debian/bsd world. A question about repositories: minimal installation (version 7) provides: CentOS-Base.repo CentOS-CR.repo CentOS-Debuginfo.repo CentOS-fasttrack.repo CentOS-Sources.repo CentOS-Vault.repo I known there are others repositories as: RPMForge, EPEL, REMI, ATrpms, Webtatic (and maybe also others) so, what kind of these repositories are? Does they repositories substitute packages from main? Or only adding new packages? thanks for advices and help! Pol
