[CentOS] Crash and automatical reboot when using the NVIDIA card
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. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] Centos 6.2 x64 after GRUB menu, black screen with blinking cursor
Dear CentOS users, I installed CentOS 6.2 x64 in a Sun Fire X4450 machine, it has 4 disks and I configured them to be a single volume (no RAID). The installer sees the volume perfectly, its 570Gb. I created two ext3 partitions, /dev/sda1 and /dev/sda2. In the logs I see they are formated correctly. All the files are installed. Then when I reboot, I get to the GRUB menu. Choose the first and only option, and immediately after that I only see a black screen with blinking cursor on top left. I've tried recreating the grub manually with : find /boot/grub/stage1 (reported it on hd0,0) root (hd0,0) setup (hd0) quit Then I try to boot and I get the same blinking cursor. I tried another approach with no luck either : replacing root=LABEL=UUID for root=/dev/sda1 just to see if this could help ... but I have the same problem. I don't really now what's going on. Is there anyway to put grub into verbose mode so I can see what exactly it is doing or looking for ? Thanks in advance.

[CentOS] CentOS 6 updating policy
I am migrating from debian to RHEL (CentOS) and I am wondering how the CentOS 6 updating system works. Suppose I install CentOS 6.1 now. Suppose in 8 months CentOS 6.2 is released. Now I issue a yum update, so my system will be updated to CentOS 6.2, or I will have an updated 6.1 ? What if I have been issuing yum update very day just to be sure there are no packages with urgent security bugs ? I am having a very updated 6.1 or an almost 6.2 ? Or are they the same thing ? I think that during this time I should be using Continous Release repository, right ? Also, which is the policy regarding new versions of software, kernel and libs ? The bugfixes will be backported or there will be major differences between, let’s say, 6.1 and 6.4 ? I couldn’t find all of these question properly answered in the FAQs Thanks in advance.
