raid resync speed?
by Les Mikesell 26 May '10

26 May '10

Has anything changed in updates that would affect md raid1 resync speed? I regularly swap a 750G drive and resync to keep an offsite copy and haven't paid enough attention to known when things changed but it seems to take much longer to sync than it did months ago, even if I unmount the partition and stop most other processes that might compete with it. -- Les Mikesell lesmikesell(a)gmail.com

LSI software raid with centos 5.4
by CList 26 May '10

26 May '10

Hi, I have been trying to install CentOS 5.4 on a Intel SR1530SHS, Intel S3200SH mainboard.. It has a 3 x 1TB sata hotswap drives with LSI software raid onboard. I had configured the LSI to have Sata0 and Sata1 with raid 1 and the third drive as a hotspare drive. Format the harddisk and installation was a breeze. The server rebooted into a blank screen and the cursor just keep blinking. Please advise. Thanks wL

26 May '10

Hi I have a linux box which has CentOS running in it. I logged into the box using root and wrote a script in the /home/proc_threads directory. saved the file and quit. I changed the file permissions such that any user could execute it using the "chmod 777 filename" command. When i log out and log in as a non-root user i was not able to execute the script though. Could some one please help in this regard. I am a newbie to linux. Thanks Jatin

Odd failure of smbd to start from init.d - CentOS 5.4
by Whit Blauvelt 26 May '10

26 May '10

Hi, We've got a fresh CentOS 5.4 box, and the only glitch so far is that /etc/init.d/smb doesn't start smbd. It claims it does - shows "[ok]" - but only nmbd ends up running. Even setting a higher debugging level in the smbd flags, nothing logs or shows on the console as to why smbd is immediatly quitting. To make it stranger, doing this works fine: . /etc/init.d/functions daemon smbd -D That's the core of how the /etc/init.d/smb file is set up to start it. Except from there it's not working - despite the reported "[ok]". Anyone seen this, or have advice on how to debug it? Thanks, Whit

Resolv.conf being overwritten
by Thomas Dukes 26 May '10

26 May '10

I am trying to add 127.0.0.1 to my resolv.conf. I added it through the system-config-network but if I reboot, its gone. I do not have the caching nameserver package installed. My ISP's nameservers are there. It must have something to do with DHCP. Also, in the network config GUI, should I select the IPv6 option for either or both network cards? TIA

SATA hotswap
by Jakub Jedelský 25 May '10

25 May '10

Hi all, I changed a bad disk (automaticly disabled from software raid1 and system for I/O error) in one of our servers and now have problem with adding new one to system without reboot. Does anybody have an experience with this? Or is it possible? :) We're using hotswap AXX6DRV3G for 6 SATA disks from Intel connected directly to MB (S5520HC from Intel too). There is AHCI as driver (enabled in bios), no HW raid. I found, something like that echo "0 0 0" >/sys/class/scsi_host/host<n>/scan but it found only sda disk which is already running.. Using CentOS 5.5, x86_64. Thanks for your ideas and replies ... and excuse my english please :) -- Jakub Jedelský e-mail/jabber: jakub.jedelsky(a)gmail.com http://dev.stderr.cz

Centos 5.4 to 5.5 fails to update lvm2 (needs newer device-mapper?)
by C R Ritson 25 May '10

25 May '10

Updating from centos 5.4 to 5.5 using an update rather than a rebuild, I get the following complaint from yum:- lvm2-2.02.56-8.el5_5.1.x86_64 from setup has depsolving problems --> Missing Dependency: device-mapper >= 1.02.39-1 is needed by package lvm2-2.02.56-8.el5_5.1.x86_64 (setup) This is from a local mirror, so checking the upstream feed in case the mirroring is incomplete I see the following:- The updates directory http://mirror.centos.org/centos-5/5/updates/x86_64/RPMS/ contains no device-mapper package, just:- lvm2-2.02.56-8.el5_5.1.x86_64.rpm The install directory http://mirror.centos.org/centos-5/5/os/x86_64/CentOS/ contains contains newer copies of both device-mapper and lvm2 than was current for centos 5.4:- device-mapper-1.02.39-1.el5.x86_64.rpm lvm2-2.02.56-8.el5.x86_64.rpm What is the right solution?

Re: [CentOS] [WTA] Automatically blocking on failed login
by Mr Gabriel 25 May '10

25 May '10

Maybe he should go with Centos based solution, because moving what ever services are on his box to a smooth wall instance, is going to be murder! I would still suggest fail2ban, I have hundreds of attempts against my server farm all day everyday, and the fail2ban scripts really help to stop my services being tied up denying logins or crashing, because each ip only gets three strikes, and is out, and that's across all servers. Also, my traffic logs are more accurate, and my average load dropped a bit too. --- Kind Regards, Mr Gabriel (bberry mail) -----Original Message----- From: "Sorin Srbu" <sorin.srbu(a)orgfarm.uu.se> Date: Tue, 25 May 2010 09:22:39 To: 'CentOS mailing list'<centos(a)centos.org> Subject: Re: [CentOS] [WTA] Automatically blocking on failed login _______________________________________________ CentOS mailing list CentOS(a)centos.org http://lists.centos.org/mailman/listinfo/centos

Naming of a Java Process in Linux
by Jatin Davey 25 May '10

25 May '10

Hi Not a specific question on CentOS but in general about java processes running on Linux boxes. I have a couple of java processes running on my linux boxes , They basically form a component of a bigger application. My point of interest is to monitor the resource usage of the java processes running on the linux box. So currently when i have these procs running on my box they show up as "java" in the ps -A command. I dont know for sure as to which java process belongs to which component of my appliacation. Hence what i do is add up all the resource utilization values for all java processes as my monitoring application relies on process names. So what i thought was , Is there a solution in linux or the way the JVM is initiated can we have process names different for different java processes. To be more specific if i have two java processes running in my system , in order to identify them properly can i have it running as java_1 or java_2 or something in those lines. Please let me know if its possible. Thanks Jatin

apache redirection
by Ski Dawg 24 May '10

24 May '10

Hello everyone, Part of our website has secured access with an SSL certificate. The problem we are running into is that the certificate is for www.domainname.com, so when they go to domainname.com (without the www. in front), the users are getting a "This connection is untrusted" warning, because the url doesn't match the certificate. I found one site that said to make a change to the apache conf file, which I have done. The change that I made is adding: <VirtualHost xxx.xxx.xxx.xxx:80> ServerName domainname.com Redirect permanent / http://www.domainname.com/ </VirtualHost> This works great to redirect the users to http://www.domainname.com when they go to http://domainname.com. The problem I am running into is if they go to https://domainname.com (straight to the secure site), I am not able to find a solution that will redirect them to https://www.domainname.com, so that the ssl certificate matches and they won't get the "This connection is untrusted" warning. I tried using the same thing as above, but changing the port number to 443, and the http to https on the redirect line, but that actually breaks the site, and only displays an error: Secure Connection Failed (Error code: ssl_error_rx_record_too_long) Is there something obvious that I am missing? Is there a better way to ensure that everyone will always end up with the www in the url, so the certificate always matches? Any thoughts and suggestions would be greatly appreciated. -- Doug Registered Linux User #285548 (http://counter.li.org) ---------------------------------------- Never trust a computer you can't throw out a window. -- Steve Wozniak

Mounting LVM disk
by Weiner, Michael 24 May '10

24 May '10

List Readers - I have a Dell server that uses the Perc 6i controller and had 5 1Tb disks installed (1 for OS and the other 4 in a Raid0 for a large storage pool). The owner of the server wanted me to swap out the 1Tb disks for 2Tb disks - easy enough I thought, but I ran into some issues trying to clone the OS disk to the new 2Tb disk, so I just did a re-install. So basically we now have 5 2Tb disks (1 for OS and the other 4 in a Raid0) like before. I was able to copy off the data that was on the original Raid0 volume and put it back on the newly created one that is now 8Tb and that worked well enough. But since I was unable to clone the original OS disk, and proceeded to simply re-install the OS, the owner apparently wants his $HOME directory copied off (which of course resides on the 1Tb OS disk). So, being a SAS disk, I purchased an ICY Dock which allows me to mount the SAS disk in an external enclosure, and plug it in via USB (SAS -> SATA -> USB). However when I do a 'fdisk -l /dev/sdc' I receive the following: [root@gc-server2 ~]# fdisk -l /dev/sdc Disk /dev/sdc: 2199.0 GB, 2199023255552 bytes 255 heads, 63 sectors/track, 267349 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk /dev/sdc doesn't contain a valid partition table Two things are a bit unusual here, first of all its not a 2Tb disk, and secondly why cant I read the partition table. Originally the OS was on an LVM volume and by default it was setup as /dev/VolGroup00/LogVol00 / ext3 defaults 1 1 My question is, is there a way to connect and mount this via USB and be able to get the $HOME directory stuff off that I failed to copy off before removing the disk?

Building an install disk on a USB key, solved
by m.roth＠5-cent.us 24 May '10

24 May '10

Ok, there's been discussion, including, I think, on the wiki web page, that syslinux is not correct. At any rate, after enough experimentation, I have a working install on a USB key. The procedure is: Using fdisk, partition your key: one partition, VFAT (type b, and toggle the bootable flag), about 9M or 10M, and a second partition big enough to hold a DVD. That should be type 83 (Linux native). mkfs -t vfat <the DOS partition) mkfs <the Linux partition liveCD-iso-to-disk <.iso, w/ full path> /dev/<USB DOS partition> mount <USB Linux partition> /mnt cp <CentOS.iso> /mnt/ You're done. You do have to tell it "install from hard disk", and then point it to the Linux partition. I just did this and tested it (or at least as far as the "searching for existing CentOS installations). mark

Bug in freeradius 1.1.3-1.5.el5_4 rpm
by Ian Forde 22 May '10

22 May '10

I upgraded one of my servers to CentOS 5.4 today. The freeradius service (radiusd) didn't start up due to permissions errors. I tracked it to the permissions on the /etc/raddb/certs/ directory being set to 640 rather than 750, so the radius user couldn't enter the directory. In the spec file from the source rpm, line 200 should read: %attr(750,root,radiusd) %config (noreplace) /etc/raddb/certs rather than the current: %attr(640,root,radiusd) %config (noreplace) /etc/raddb/certs Note that this bug also exists in the the 1.1.3-1.4.el5 version that's part of the CentOS 5.4 release.

Re: [CentOS] setup firewall with 3 nic cards

Hi Jerry, Just a general remark. When deploying a firewall, it is advisable to have (atleast for input, better for all) to have the general policy set to drop, and only allow in what you expect to be coming in. If you put a "-j log" line as a final line for each section, you'll see every packet you forgot about... Now the default is "allow", and only doing some SNAT and DNAT rules... hw -----Original Message----- From: centos-bounces(a)centos.org [mailto:centos-bounces@centos.org] On Behalf Of Jerry Geis Sent: Tuesday, May 11, 2010 12:10 AM To: CentOS ML Subject: [CentOS] setup firewall with 3 nic cards I have a centos box with 3 nics. eth0 is internal, eth1 is T1 data and eth2 is cable data.

Re: [CentOS] OT: Strange Email Problem
by Mr Gabriel 21 May '10

21 May '10

You might want to run your MTA's ip address through a blacklist checker. Also, do you use srv records? Has anything here changed? I've found that when it comes to email, its quite plausible for your system to break because of an external party, for example, do you use the relay of your ISP? If you do, run their ip through a blacklist db, in case someone on their end has been spamming. If you didn't change anything, then consider the above factors, I hope it helps :) --- Kind Regards, Mr Gabriel (bberry mail)

Can't umount flash drive because an application has it locked
by MHR 21 May '10

21 May '10

This occasionally happens to me when I've been editing an OOo document that resides on a flash drive I use with one of my laptops. I've tried poking around in ps to find out which process has the drive locked, and I can't figure it out. Nothing directly refers to the flash drive except one of the hald processes, and it's just scanning the drive (I tried killing that and it made no difference). My usual sequence of events is as follows: 1. Plug in the flash drive. 2. Wait for it to appear on the desktop. 3. Start up a terminal window (which recognizes the flash drive and runs sudo to allow execute permissions on the drive). 4. Run the script that unzips the files I want. 5. Open the file with the OO writer, edit it for a while, then save and close it. 6. Update the zip archive (on the flash drive). 7. Close the terminal window. 8. Umount the drive, which fails. I've tried waiting for as much as five minutes, running sync - nothing. The last three times this happened, I had to shut down the laptop (which I was going to do anyway) in order to free the flash drive. This takes several minutes, which can be precious when I need to bag the laptop in a hurry. There's nothing in any of the syslogs. The laptop was just updates to the L&G CentOS 5.5. What am I missing? Thanks. mhr

Grub Error 22; no Windows
by Jeff Sadino 21 May '10

21 May '10

Hello, I have a GridEngine setup with 5 subnodes and two RAIDS attached. I backed up the OS drive - 120GB - to an external hard drive - 500GB - using ddrescue. The OS drive is partitioned as: sda1 has the OS and is about 7 GB sda2 has /var and is about 4 GB sda3 has swap and is about 1 GB After backing up, there were 4KB of errors, but all at the end of the disk around 118GB. This used to be a partition back in the day, but I deleted it accidentally. I want to back up to this new larger disk b/c the original 120GB disk is discontinued. I boot from a live cd - SystemRescue CD - and run e2fsck -c -c -C 0 y on sda1 and sda2 on the backup drive, and it seems to finish fine. Then I replaced the OS drive with the backup drive, and it goes to boot, then Grub Loading Stage 1.5; Error 22. Here's the important stuff from fstab: # This file is edited by fstab-sync - see 'man fstab-sync' for details LABEL=/1 / ext3 defaults 1 1 none /dev/pts devpts gid=5,mode=620 0 0 none /dev/shm tmpfs defaults 0 0 /dev/md0 /export ext3 defaults 0 0 none /proc proc defaults 0 0 none /sys sysfs defaults 0 0 LABEL=/var /var ext3 defaults 1 2 LABEL=SWAP-sda3 swap swap defaults 0 0 /dev/sdb1 swap swap defaults 0 0 # The ram-backed filesystem for ganglia RRD graph databases. tmpfs /var/lib/ganglia/rrds tmpfs size=252709000,gid=nobody,uid=nobody,defaults 1 0 /dev/hda /media/cdrom auto pamconsole,exec,noauto,managed 0 0 I boot up from the live cd, and then tell it to search for bootloaders on the drives, and it finds one, and it goes through, and then throws errors b/c it is mounting the OS /sda1 drive and then trying to run fsck on it. I tried setting the error-check values to 0 for /1 and /var, but it is still trying to error check it. My blkid says that sda1, sda2, and sda3 all have different UUIDs. sdc1, sdd1, and md0 all have the same UUID. md0 is a RAID1 comprised of sdc1 and sdd1. sdc and sdd are identical drives. This used to happen, and I would just restart a couple of times, and it would sneak on past the error eventually, but to no avail this time. Does anyone have any ideas? Thank you so much! And thank you to the dozen people who offered advice on the best backup option. After reading all of the replies and the links, I think I will prob go with the rsync-backup suggestion. Mahalo, Jeff

5.5 ISO size vs RHEL
by Anthony Caetano 20 May '10

20 May '10

Hi We use CentOS and RHEL, the 5.5 RHEL ISO for x86_64 is 3.7GB (**), the CentOS one is 4602MB (***) split over two DVDs. Is this reasonable and correct? Any ideas why would there be such a discrepancy if they are built from the same (or very similar) source? Regards Anthony Caetano ** the md5sum checks out, and RHN lists the size as 3,532 MB *** CentOS-5.5-x86_64-bin-DVD-1of2.iso + CentOS-5.5-x86_64-bin-DVD-2of2.iso (according to ftp.heanet.ie:/pub/centos/5.5/isos/x86_64 )

I'll try that tomorrow. *sigh* Well, I did that, and then went through a song-and-dance uninstalling the stuff the nvidia installer had put in, and uninstalling this so that would succeed, and then *really* getting rid of the stuff it wouldn't, and then using yum again. And it still got trash. My user's sure he had not turned it off, that he just came in one morning and it had lost it, and I have every reason to believe him (he *does* know what he's doing). So, at this point, we've given up - his machine wasn't on a UPS, and given the power in this building, there's a high probability of a surge, and something on the card got fried - so he's got another machine, and we're probably going to call this one dead. Thanks, though, for the el repo link. I've got to remember that one. mark

Hi, I have updated 8 machines so far and 2 are refusing to boot on 2.6.18-194.3.1.el5 kernel, they just hang at: 'Starting udev:' but when I revert to 2.6.18-164.15.1.el5 kernel they boot fine. Any pointers? Cheers, Colin.

How to create a printer that prints directly to a file?

I am trying to learn how to share printers using samba. I am doing most of my experiments at home w/ libvirt and where there are no printers. How can I set up a printer device that just prints to a file on my system? That would really help me in my experiments.

Networking setup/help
by tdukes＠sc.rr.com 20 May '10

20 May '10

I had to install 5.5 from scratch and now I have to rebuild my home networking system. I haven't had to mess with this stuff in over 5+ years and I'm sure there may be better ways of doing it now. My liunx box acts as firewall/gateway for 2 other pcs. I was using a script from the Linux IP Masquerade HOWTO with ddclient (since I have a dynamic ip). Also, I don't think I need a full name server. Can I get by with a caching nameserver? Thanks!! Eddie

Generic RAID question
by James Bensley 19 May '10

19 May '10

Does anyone know if using unequal drives in a RAID 0 is possible? I was looking to set up a software stripe but if I have two volumes of unequal size I wish to stripe over, will the OS try and work around this by say only using as much space as is available on the smallest drive or is there anyway it will use all of both drives? Does it have to be a perfect block/byte balance across drives? (I'm assuming yes?) -- Regards, James. http://www.jamesbensley.co.cc/

trying to rebuild an old nvidia driver
by m.roth＠5-cent.us 19 May '10

19 May '10

Let me start by saying that no, I can't get a new card for my user. So, I've got the 96 nvidia driver. I've rebuilt it several times before, and Nvidia's installer's always worked fine. Actually, I have the 73 on my system, and just updated to 5.5, and no problem. HOWEVER, I last rebuilt my user's driver back in mid-April, after the last kernel update (was that mid-March?), and everything was fine... until the other day, when he walked in to tell me he'd had to reboot, and it wasn't working, and dropped him to command line. I rebuilt it... and it dies. As in, sometimes, I have to go to another machine and ssh in to reboot, and sometimes, I have to power cycle his system. I get garbage with the nvidia driver; with nv, I can at least get one of his two monitors working. When I try x with the nvidia driver, it just keeps printing out initializing GART, I think it is (I've lost the log), and then that it has failed to allocate ROP. Anyone see anything like this? I've unpacked the executable, and started working with the makefiles (and yes, I do understand makefiles), but see things like a lot of warning in the compile, and the one that makes me nervous is make CC=cc KBUILD_OUTPUT=/lib/modules/2.6.18-194.3.1.el5/build KBUILD_VERBOS E=1 -C /lib/modules/2.6.18-194.3.1.el5/source SUBDIRS=/scratch/NVIDIA-Linux- x86-96.43.13-pkg1/usr/src/nv modules make -C /lib/modules/2.6.18-194.3.1.el5/build \ KBUILD_SRC=/usr/src/kernels/2.6.18-194.3.1.el5-i686 \ KBUILD_EXTMOD="/scratch/NVIDIA-Linux-x86-96.43.13-pkg1/usr/src/nv" -f /usr/ src/kernels/2.6.18-194.3.1.el5-i686/Makefile modules test -e include/linux/autoconf.h -a -e include/config/auto.conf || ( \ echo; \ echo " ERROR: Kernel configuration is invalid."; \ echo " include/linux/autoconf.h or include/config/auto.conf are mis sing."; \ echo " Run 'make oldconfig && make prepare' on kernel src to fix it ."; \ echo; \ /bin/false) Even though both those files exist and are where they should be. I've googled, and find no references to those, and really hope it's not the card going bad.... So, any clues? mark

CentOS 5.5 - VMware Fencing in Cluster
by James 19 May '10

19 May '10

I'm trying to use the newly integrated fence_vmware script within luci. I add it as a shared device and assume it is setup right (it is added as a device but it doesn't seem to do any connection test). When I try and add my shared fencing device as the primary device to a node it says it is updating the node configuration but then doesn't actually add the fence in the node's configuration within luci. If I try and fence the device it predictably fails to fence the device. I tried using fence_vmware from the command line (which seem to have some trivial errors which keep it from even running) and it works fine (after I fixed fence_vmware). Can anyone offer me advice on setting up the shared fence and applying it to nodes for VMware Fencing?
