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?

dovecot informational/error messages?
by Timothy Murphy 22 Nov '13

22 Nov '13

I'm getting the message Nov 22 13:06:56 grover dovecot: imap-login: Disconnected (no auth attempts): rip=192.168.2.3, lip=192.168.2.5, TLS: Disconnected every second on my CentOS-6.4 server. Is this purely an informational message? Or is it an error message? And in either case, how can I stop the flood of messages? -- Timothy Murphy e-mail: gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin 2, Ireland

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? I know that I will need to add to my grub.conf . -- Michael hennebry(a)web.cs.ndsu.NoDak.edu "On Monday, I'm gonna have to tell my kindergarten class, whom I teach not to run with scissors, that my fiance ran me through with a broadsword." -- Lily

by Wes James 20 Nov '13

20 Nov '13

I'm trying to find the correct vpn plugin so I can vpn in to a server. The server requirements are vpn server, username/password and shared secret. I've installed a few vpn plugins, but I haven't found the correct one that has the shared secret option. Anyone know which one it is? I've tried a few from the Add/Remove Software application. Thanks, -wes

Any experience with lanner appliances?
by John Doe 20 Nov '13

20 Nov '13

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... Thx, JD
