RAM Requirements
by Mark LaPierre 24 Nov '13

24 Nov '13

Hey Y'all, Does anyone know where I can look, please post a URL, where I can find out what the minimum system requirements are for CentOS 6.4? I've searched the CentOS.org web site for this but I've come up empty. I've got an old machine that had RH9 on it. The HD died so I had to replace that. Now I'm thinking that I want to install CentOS 6.4 on it but the minimal install disk says that I don't have enough RAM for it to do the install. -- _ °v° /(_)\ ^ ^ Mark LaPierre Registered Linux user No #267004 https://linuxcounter.net/ ****

Crash and automatical reboot when using the NVIDIA card
by David McGiven 23 Nov '13

23 Nov '13

Hello there, I'm running a Supermicro server with the latest CentOS 6.4 versions (kernel : 2.6.32-358.23.2.el6.x86_64) and the latest nvidia driver (331.20). A few minutes after using the GPU for doing some HPC calculations, the server crashes and reboots itself. This is happening every time. I know it will be rebooted but I don't know when. Sometimes it's 20 minutes after starting using it. Sometimes it's 2 hours. If I unplug the GPU card and put some stress on the server, it works ok. So I suspect there's a bug in the kernel/nvidia driver. I can't find any messages on /var/log/messages. What should I do ? Should I file a bug on the centos bugtracking system ? Is there anyway I can gather more information ? The server is in a remote location so I have a hard time accessing the console. Thanks.

nfs4, idmapd, users with same name, different uid?
by Les Mikesell 22 Nov '13

22 Nov '13

Is idmapd supposed to work where users have different uid numbers on the nfsv4 server and client? It seems to show the right names for ownership on the client side, but if I automount a home directory, that user doesn't have permission to enter it, and if I change permission to allow access and create a new file, it shows on the server as owned by the uid number for the user on the client (and wrong on the server). Everything works like it would on nfs v3 where the uid numbers are the same on the client and server, but what's the point of the rpcidmapd daemon if it doesn't actually map the ids? -- Les Mikesell lesmikesell(a)gmail.com

SSSD with 389DS
by Mitja Mihelič 22 Nov '13

22 Nov '13

Hi! We are setting up an environment with two 389DS configured as master-consumer. The DIT holds about 70.000 user records. A couple of other machines running SSSD will be using the 389DS setup for all user info lookups that would normally go to passwd/shadow. There are also other applications that will be querying the 389DS for various other user data. All servers are running CentOS6. In total I would estimate that SSSD would be handling about 400 queries per second. How should I configure SSSD to get the most out of it? Cache refreshes, (negative) timeouts, expirations, enumerations?

quota doesn't appear to work - repquota only updates when quotacheck is run
by Matt Garman 21 Nov '13

21 Nov '13

I have set up user quotas on an ext4 filesystem. It does not appear that the quota system is being updated, except when I manually run quotacheck. More detail: I run "warnquota -s" from a script in /etc/cron.daily. I noticed that no one had received an "over quota" message in a long time. Using "repquota -as", it indeed looked as though everyone was under their quotas. But "du" showed many people were over quota. So I did a "quotaoff -a ; quotacheck -vam ; quotaon -a". That night, several warnquota-generated messages went out. My users diligently cleaned up their homes. Fast forward 24 hours, and the users received the same warnquota emails. repquota showed them as being over, but "du" told a different story. System is CentOS 6.3, kernel 2.6.32-279.2.1.el6.x86_64. # dmesg | grep -i quota VFS: Disk quotas dquot_6.5.2 The partition is type ext4 mounted at /share: # cat /proc/mounts | grep share /dev/mapper/VolGroup_Share-LogVol_Share /share ext4 rw,noatime,nodiratime,barrier=0,nobh,data=writeback,jqfmt=vfsv0,usrjquota=aquota.user 0 0 The ext4 volume sits on top of an lvm logical partion. That logical volume ultimately sits on top of an encrypted disk using cryptsetup luksFormat: # lvscan ACTIVE '/dev/VolGroup_Share/LogVol_Share' [4.48 TiB] inherit # pvscan PV /dev/mapper/luks-7f865362-ee9f-40de-bc07-73701b4662f3 VG VolGroup_Share lvm2 [4.48 TiB / 0 free] Is there something in my ext4 mount options that is incompatible with quota? Or maybe the encrypted layer is causing problems? Am I missing something else? Thanks!

restarting network interface
by Wes James 21 Nov '13

21 Nov '13

I googled to see how I might restart the network interface in CentOS. I initially tried before googling: sudo service network restart I noticed that only the loopback interface was restarted. To confirm this I did: service network stop and then did ifconfig and the loopback info was gone. I then found ifconfig eth0 up/down and tried those and that did what I is was looking for. Why doesn't "service network restart" restart all interfaces? Thanks, -wes

CentOS still dies on me
by Michael Hennebry 21 Nov '13

21 Nov '13

Might this have something to do with the following boot message?: Starting virt-who: Traceback (most recent call last): File "/usr/share/virt-who/virt-who.py", line 33, in <module> from subscriptionmanager import SubscriptionManager, SubscriptionManagerError File "/usr/share/virt-who/subscriptionmanager.py", line 24, in <module> import rhsm.connection as rhsm_connection ImportError: No module named rhsm.connection ^[[60G[^[[0;31mFAILED^[[0;39m]^M Starting libvirtd daemon: ^[[60G[^[[0;32m OK ^[[0;39m] If not, I'd like to test the idea that my problem with Linux dying on me is that recent kernels do not like my computer. My most recent installation that still runs reliably is Fedora 14. If I copy a kernel from F14 into my CentOS installation, what else do I need to copy with it?

Any experience with lanner appliances?

Hi, anybody has installed CentOS on an lanner appliance...? Eg. http://www.lannerinc.com/products/all-purpose-box-computers/industrial-auto… I was planning to buy an hp microserver to make a "small" CentOS firewall (and more since it is overpowered), but I am wondering if I could go for a lot smaller and with no fan/noise... but at the same time a bit more expensive...

CentOS LiveCD on USB
by Glenn Eychaner 20 Nov '13

20 Nov '13

I have been following these instructions: https://www.centos.org/forums/viewtopic.php?t=501 to put a bunch of utilities (Clonezilla, SystemRescue, CentOS netinstall/rescue, etc.) on a single USB key. It works great for everything (including Ubuntu Live) except the CentOS 6.4 LiveCD. (You can see my postings at the bottom of the forum.) When booting the LiveCD, I got: Kernel panic - not syncing: Attempted to kill init! Pid: 1, comm: init Not tainted 2.6.32-358.el6.i686 #1 After removing "quiet" and adding "selinux=disabled", I got more information; the boot stalls after finding devices, and gives: No root device "block:/dev/mapper/live-rw" found dracut suggests adding "rdshell", which I did. This was not helpful (I had no idea what to do in the dracut shell), but did notice that in the dracut shell /dev/ did NOT seem to contain my USB drive at /dev/sdb as I would expect. (One reason it seemeed not helpful) So: 1) I used VFAT rather than ext2/3/4. Do I have to use ext2/3/4? 2) Do I need to rebuild the initramfs file somewhere in the CentOS LiveCD directory? 3) Is this just a straight-up hardware incompatibility? The computer is a brand-new SuperMicro X10SAE Haswell system. Thanks, -G. -- Glenn Eychaner (geychaner(a)lco.cl) Telescope Systems Programmer, Las Campanas Observatory

VNC

I had posted last week about trying to get VNC working. I was never successful nor were multiple admins. But we realized that all the hosts we tried on were VMs. We followed the same procedure ( http://wiki.centos.org/HowTos/VNC-Server) on a machine with physical HW and it worked with no problem. But on the VM I can connect, but I don't get any window displayed.

Emacs 24 on CentOS 6.4
by Carson Chittom 19 Nov '13

19 Nov '13

I'm fairly new to CentOS, so please excuse my ignorance. I've installed CentOS 6.4, for which Emacs 23 is available; but I'd like to have Emacs 24. I've looked at rpmforge and epel, but neither seem to have Emacs 24 already packaged; and I've searched for every combination of emacs + 24 + centos without success. While I could, of course, just do the ./configure && make && make install dance, I don't like having software installed that's not in the packaging system. I'd appreciate any pointer to a prepackaged Emacs 24, or failing that, a good tutorial on how to package software correctly for CentOS.

What is the maximum number of NFS mounts per client? I have an instance where there are over 400 mount points using autofs. I was wondering if there is a downside to that. -- --- Get your facts first, then you can distort them as you please.--

CentOS 5.7 - occasional lockup
by whitivery 18 Nov '13

18 Nov '13

Using Core i7 boxes with CentOS 5.7, have experienced lockups on half of a handful of units over a couple months. They are Logic Supply Mini-ITX model KR960 with Core i7-3610QE. A couple weeks ago I enabled self-reboot on kernel panic (echo 10 > /proc/sys/kernel/panic) on all units, and had another unit lock up rather than reboot itself. I'm not sure how to pursue the problem. Doing "yum update kernel*" shows there's a newer kernel, 2.6.18-371.1.2.el5 - I'm using the stock 2.6.18-274.el5 kernel now - where's a change log of the differences so I can see if there are driver or kernel updates that might seem to apply? I don't know if setting up kdump would help since it doesn't even seem to be getting to the point where the kernel is trying to handle a panic. What else might I try?

Saving Workspace State
by Michael B Allen 17 Nov '13

17 Nov '13

Is there a way to save the position and workspace locations of at least terminals on logout? I want to have many workspaces with 2-3 terminals each for editing code and scripts and ssh and so on. The System > Preferences > Startup Applications > Options > Automatically remember running applications when logged out doesn't work. And gnome-session-save doesn't work either. I used to use Fedora 14 and it saved the session state fine. But now I cannot recall how to do it. I know GNOME 3 removed that code (the GNOME developers now believe that the applications should remember their own state) but I was hoping CentOS still has this capability. Is it possible to save GNOME desktop session state in CentOS 6? Mike

Module signed with unknown public key
by Timothy Murphy 17 Nov '13

17 Nov '13

I recently had a hard disk failure on my CentOS-6.4 server. I re-intalled CentOS on a second disk, and this is working fine. But I put together the old system - most partitions on the old disk could still be read - and made a working system. But when I re-start this system I get the above message many times. (Also I can only login in text mode, and when I run startx I get the error "Fatal server error: no screens found." And ifconfig only gives the lo interface; it does not show eth0 and eth1, so I am unable to access the internet.) But how can one "sign" a module? I googled for this, but all the suggestions were about signing modules while compiling them. It seems odd too that the error message does not tell me which module it is referring to. But the error is repeated about as many times as the number of modules listed by lsmod, so I guess every module is wrongly signed. Any enlightenment on this subject gratefully received. -- Timothy Murphy e-mail: gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin 2, Ireland

CentOS 6 and Intel vPro?
by Lists 16 Nov '13

16 Nov '13

Needed to set up a cluster where horsepower and cost were paramount, so I thought this would be a good opportunity to try out Intel's business class "vPro AMT" remote administration technology, and compare it to IPMI, which I've used for years on servers. From a feature standpoint, it seems quite impressive, going to far as using standards-based VNC! Unfortunately, set up is quite a bear, with most of a day spent and while I can remote power cycle the machine via a web interface, VNC support is still not to be found. I have no intention of buying Windows licenses for all these machines just so I can enable AMT. (the VNC remote desktop solution) So far, it would seem that the Intel approach is very Windows-oriented, to the point where I've been unable to find any official documentation at all as to how to make it work with *nix. After some googling and trying to make sense of the "enterprise reference documentation" I came across http://blog.yarda.eu/2012/09/intel-amt-quickstart-guide.html which apparently was working as recently as October of this year. (see the comments) However, it would seem that intel has pulled support for some of this, as pages like http://intel.com/wbem/wscim/1/ips-schema/1/IPS_KVMRedirectionSettingData and http://schemas.dmtf.org/wbem/wscim/1/cim-schema/2/CIM_KVMRedirectionSAP simply resolve to 404, numerous attempts to google "IPS_KVMRedirectionSettingData" and such haven't (so far) returned anything useful. From what it seems, Intel wants everybody to be installing PKI AMT certificates on vPro motherboards via Windows. Does anybody have any information that might be useful about how to enable unencrypted VNC remote administration for CentOS based servers? I have a used KVM switch, but that's always been a sub-optimum solution, and it really makes a mess out of your server cages.

No, image formats have standardized binary representations so they are portable. The problem is with applications that write their own binary values and data structures to disk without conversion. I don't know much about msyql internals, but I wouldn't expect it to go to the trouble of normalizing things like index files just in case you wanted to move those disks to a sparc instead of doing a dump/load. -- Les Mikesell lesmikesell(a)gmail.com

Expanding EVMS raid1 array
by Peter Crighton 15 Nov '13

15 Nov '13

I started with two 160GB drives in RAID1 using EVMS on Centos 4.4. Both drives have now been replaced with 320GB drives but naturally are only offering 160GB (they were replaced individually at different times and self-recovered as they were RAID1. I cannot work out how to increase the size of the array to use all the available space on the disk. If I understand correctly, I should unmount the array, deactivate it and select expand. The problem is that while I can unmount and deactivate it, there is nothing to expand (selecting expand volume, expand storage object and expand container all report no items found). Also, right clicking on the array (in EVMSGUI) doesn't have expand as an option. The disks are formatted in Ext2/3. Have I missed something? I'd rather not replace the old drives, create a second RAID array and copy all the data across as I've a feeling that I'll then have to reset permissions and shares (although I just might get away with then removing the original RAID array and mounting the new one in the same location). In my mind it also ought to be easier to simply re-size the array than have to set up new ones and move the data across. -- Peter Crighton

Mysql databases from old system?
by Timothy Murphy 15 Nov '13

15 Nov '13

Last week I had a hard disk failure on my CentOS server. I managed to re-install CentOS on a new disk. I have the old mysql databases from /var/lib/mysql . Can I just move them to my new disk? Any help or suggestions gratefully received. -- Timothy Murphy e-mail: gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin 2, Ireland

First Time Setting up RAID
by James B. Byrne 15 Nov '13

15 Nov '13

Arch = x86_64 CentOS-6.4 We have a cold server with 32Gb RAM and 8 x 3TB SATA drives mounted in hotswap cells. The intended purpose of this system is as an ERP application and DBMS host. The ERP application will likely eventually have web access but at the moment only dedicated client applications can connect to it. I am researching how to best set this system up for use as a production host employing RAID. I have read the (minimal) documentation respecting RAID on the RedHat site and have found and read a few online guides. Naturally, in my ignorance I have a bunch of questions to ask and I probably have a bunch more that I should but do not know enough yet to ask. >From what I have read it appears that the system disk must use RAID 1 if it uses RAID at all. Is this the case? If so, is there any benefit to be had by taking two of the 8 drives (6Tb) solely to hold the OS and boot partition? Should these two drives be pulled and replaced with two smaller ones or should we bother with RAID for the boot disk at all? Given that one or two drive bays will be given over to the OS what should be the configuration of the remaining six? It appears from what I have read that RAID 5 is the only viable option. It also appears that the amount of storage available on a RAID5 array with N members is N-1/N. I also read that as the number of members increase both latency and the risk of data loss increases. As the amount of disk space we have in this unit (24Tb) is greater than the total storage of all our existing hosts it appears that a RAID5 array of 5 units would leave at least one hot spare in the chassis and two if the OS is put on one disk. Alternatively, the thought comes to mind that we could do a RAID1 with two RAID5 arrays each of which have 3 drives. Whether one would actually want to do that seems to me a bit questionable but it seems to be at least possible. Comments, suggestions, caveats?

Is that right? I am just getting started with this so I am trying to fit what I am reading regarding RAID with what I have dealt with in the past, mainly LVM ext3 volumes. So I am doubtless just not getting it in some important way. BTW, I intend to install CentOS-6.4 with software RAID as the eight disks are mounted in the system chassis. As far as I can tell, there is no hardware RAID controller (unless there is one on the MB, in which case SW Raid is likely a better choice anyway.

Problem with X11 application and Nouveau driver
by Glenn Eychaner 14 Nov '13

14 Nov '13

I have finally received and am configuring my new workstations eith the NVS510 graphics cards, and have run into rather a problem. The X server seems to be loading the NOUVEAU driver properly (based on the contents of Xorg.0.log), but I have one X11 application that doesn't work correctly; it runs as though XSynchronized is always True, even though it's explicitly set to False in the code. In other words, its redraw behavior is god-awful; worse because it auto-redraws once per second for little apparent reason. And some of the windows draw with artifacts if they're covered and uncovered. Any ideas, anyone? I will gladly provide more info on request, but I'm not an expert X11 programmer (worse, this application uses a third party wrapper library). This is definitely new behavior on this new computer (the previous computers, also using the Nouveau driver with GeForce 7600 cards, did not seem to have this behavior). -G. -- Glenn Eychaner (geychaner(a)lco.cl) Telescope Systems Programmer, Las Campanas Observatory

I have seen soft loose data reliably, were in the same environment (and same equipment) hard,intr does not loose data. My experience is that intr is useful in situations where servers go down/have link issues frequently, and autofs with short timeouts (~15s < timeout <~60s) makes those issues even less _visible_. It will not get you an automatic unmount of the share and error to the client app in the case of server down, but it will /allow/ you to terminate the client and unmount as needed IIRC.

Tuning MySQL - what's the best place for mysqld parameters?
by Alexander Farber 13 Nov '13

13 Nov '13

Hello CentOS users, for a Wordpress website I have installed mysql-server-5.1.69-1.el6_4.x86_64 and run /usr/bin/mysql_secure_installation on a CentOS 6.4 machine with mucho RAM (32 GB) and I wonder, what would be the best place for the mysqld parameters descibed at http://dev.mysql.com/doc/refman/5.1/en/server-parameters.html mysqld_safe --key_buffer_size=64M --table_open_cache=256 \ --sort_buffer_size=4M --read_buffer_size=1M & Should I just edit the file /etc/init.d/mysqld or is there a better place in CentOS for that (under sysconfig?) Thanks Alex

strange speed of mkfs Centos vs. Debian
by Götz Reinicke - IT Koordinator 13 Nov '13

13 Nov '13

Hi, I'm testing a storage system and different network settings and I'm faced with a strange phenomen. Doing a mkfs.ext4 on the centos server lasts 11 minutes. The same mkfs.ext4 command on the debian installation is done in 20 seconds. It is formatting a 14 TB 10Gbit ISCSI Target. It is the same server. Centos and debian are installed on different internal harddisks. Any explanations why debian is so f*** fast? Any hint? Regards .

Using CentOS Wordpress rpms
by Max Pyziur 13 Nov '13

13 Nov '13

Greetings, Apologies for my seeming daft naivete. I'm wondering if there any sort of conventions for using Wordpress on CentOS? Generally until now, I have had users install Wordpress from tarballs on a case-by-case basis. This means that you can have several different versions of WordPress operating on a site. With the RPM you have a version that can be consistent across multiple websites on one server. Is this done through the use of symlinks, or is there some other, additional magic that gets put to use. I've done a little searching of the Google genie, but I'm only led to webpages outlining installing Wordpress from tarballs. Much thanks, Max Pyziur pyz(a)brama.com

NFS hard mount
by Rita 13 Nov '13

Is there a tunable to set NFS hard mount time out? For instance, if the server becomes unavailable for extended amount of time, say 1 hour. I would like to timeout after 30 secs. (Soft mount isn't an option, BTW) -- --- Get your facts first, then you can distort them as you please.--
