init/upstart issue? ypbind and autofs
by Lars Hecking 12 Mar '12

12 Mar '12

One problem I have with custom CentOS 6 installation is that NIS auto.* maps are not available. According to boot.log, ypbind starts before autofs, but when I login to the machine, the maps are not available until I issue a service autofs restart. Any pointers on what to check?

gdm in 6.2 missing keyboard menu?
by James Pearson 07 Mar '12

07 Mar '12

I have a box running 6.0 that gives a keyboard layout menu via gdm when logging in. I've just installed a 6.2 box, but there is no keyboard layout menu I've found a bugzilla entry at: <https://bugzilla.redhat.com/show_bug.cgi?id=746923> which says that with gdm in 6.2, it now only shows keyboard layouts listed in /etc/sysconfig/keyboard However, I've added a list of keyboard layouts as suggested by that BZ, but I still don't get a keyboard menu. Is there anything else I've missed? Thanks James Pearson

I do not really use the other parts so on those I cannot comment. In fact, the experience is far better than I had with OpenOffice-3.3, which was so bad I went back to the 3.2 version provided with CentOS. -- *** E-Mail is NOT a SECURE channel *** James B.

Software RAID1 with CentOS-6.2
by Kahlil Hodgson 07 Mar '12

07 Mar '12

Hello, Having a problem with software RAID that is driving me crazy. Here's the details: 1. CentOS 6.2 x86_64 install from the minimal iso (via pxeboot). 2. Reasonably good PC hardware (i.e. not budget, but not server grade either) with a pair of 1TB Western Digital SATA3 Drives. 3. Drives are plugged into the SATA3 ports on the mainboard (both drives and cables say they can do 6Gb/s). 4. During the install I set up software RAID1 for the two drives with two raid partitions: md0 - 500M for /boot md1 - "the rest" for a physical volume 5. Setup LVM on md1 in the standard slash, swap, home layout Install goes fine (actually really fast) and I reboot into CentoS 6.2. Next I ran yum update, added a few minor packages and performed some basic configuration. Now I start to get I/O errors on printed on the console. Run 'mdadm -D /dev/md1' and see the array is degraded and /dev/sdb2 has been marked as faulty. Okay, fair enough, I've got at least one bad drive. I boot the system from a live usb and run the short and long SMART tests on both drive. No problems reported but I know that can be misleading, so I'm going to have to gather some evidence before I try to return these drives. I run badblocks in destructive mode on both drives as follows badblocks -w -b 4096 -c 98304 -s /dev/sda badblocks -w -b 4096 -c 98304 -s /dev/sdb Come back the next day and see that no errors are reported. Er thats odd. I check the SMART data in case badblocks activity has triggered something. Nope. Maybe I screwed up the install somehow? So I start again and repeat the install process very carefully. This time I check the raid array straight after boot. mdadm -D /dev/md0 - all is fine. mdadm -D /dev/md1 - the two drives are resyncing. Okay, that is odd. The RAID1 array was created at the start of the install process, before any software was installed. Surely it should be in sync already? Googled a bit and found a post were someone else had seen same thing happen. The advice was to just wait until the drives sync so the 'blocks match exactly' but I'm not really happy with the explanation. At this rate its going to take a whole day to do a single minimal install and I'm sure I would have heard others complaining about the process. Anyway, I leave the system to sync for the rest of the day. When I get back to it I see the same (similar) I/O errors on the console and mdadm shows the RAID array is degraded, /dev/sdb2 has been marked as faulty. This time I notice that the I/O errors all refer to /dev/sda. Have to reboot because the fs is now readonly. When the system comes back up, its trying to resync the drive again. Eh? Any ideas what is going on here? If its bad drives, I really need some confirmation independent of the software raid failing. I thought SMART or badblocks give me that. Perhaps it has nothing to do with the drives. Could a problem with the mainboard or the memory cause this issue? Is it a SATA3 issue? Should I try it on the 3Gb/s channels since there's probably little speed difference with non-SSDs? Cheers, Kal

Centos6: Boot from usb 3.0
by Volker Poplawski 02 Mar '12

02 Mar '12

Hi all, I'm booting Centos6 from a usb 3.0 stick. This works fine as long as the usb-stick is connected to a usb 2.0 port. Once I plug the the usb-stick into a blue usb 3.0 port centos fails on mounting the root filesystem. Any hints on that? Regards .....Volker

Is there a way to _remove_ dependencies from an RPM built from source?
by Michael Lampe 02 Mar '12

02 Mar '12

I'm building my own openmpi packages derived from upstream SRPMs. Problem: The ones built with Intel's compiler can only be installed by force, because Intel doesn't register their provided libs with rpm. Any idea how this can be done? (Alternative ideas are appreciated as well -- as long as they don't read as: make Intel fix this.) -Michael
