[CentOS] Upgrade then sudden death..
I recently put Cent 5.2 (64 bit) on a new server using a Supermicro pdsbm-ln2+ sys board. I did the original installation at home using the 5.2 dvd I got via torrent. I turned it over to my NOC tech and it went right online so he ran yum update. With the most recent kernel, which went in with the update, the server hung on grub (after reboot). He did a fresh (minimal) Centos installation and once again ran update, but again the new kernel wouldn't load. The machine is set up RAID 1 with two Seagate 250 GB sata drives. Nothing fancy, just cheapo 7200 rpm stuff. I wish I could be more specific, but I wasn't present during the update and failure. None the less, I would appreciate all the opinions and feedback you folks can offer. I'll have the server back here in a couple of days. In the meanwhile, I'd like to get some ideas that could help me resolve this issue. I put the system board manual on my server at: http://hwy39.net/centos/Supermicro_PDSBM-LN1-LN2-LN2+_Manual.pdf . Feel free to take a look at it. -- Thanks, Ben hwy39.net lonsingerpharmacy.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

SATA drive handling, and I've even reported on this myself in this list before. My question is, do we have any idea if 5.3 has any improvements in this area? One of my cohorts here, who happens to be a Fedora fan, says that these problems are fixed in F9, but I have grave concerns about putting an enterprise lifeline main application on any Fedora release. If 5.3 solves these issues, I'd much rather go with that. Any ideas? Any places I might look to see for myself? The only issue I've ever seen has been with the onboard fakeraid stuff more and more vendors seem to be adding. I've been using SATA disks with centos since the early 4.x days without issue, so you have me at a bit of a loss here. I'd say if anything it's due to controller support, and much of that can be chalked up to what hardware vendors are pawning off as 'controllers' these days. I recently set up a CentOS 5.2 server with RAID 1 (software) and 2 sata drives. During burn-in I see no problems. I'm using a Supermicro PDSBM series system board.

[CentOS] Setting clock rate on CentOS kernel
Last evening I updated my Cent 5 server to 5.1. All went flawlessly, and it rebooted with the new kernel just fine. How do I set the clock rate on the new kernel? According to documentation it can be done, but everything I read is rather vague. Check out section 3 at the URL below: http://wiki.centos.org/Manuals/ReleaseNotes/CentOS5.1/ I'm using a 32 bit server installation (no graphical stuff) on a Dell Poweredge 2650. I'd like to compare performance of a 100 Hz kernel against a 1KHz kernel. It reads like it's simple enough to set the divider if I just knew where to set it. -- Ben ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

That section applies only if you are running CentOS in a virtual machine. Is this the case?? No, it's physical. After you replied, I found a good read on the divider and I began to understand it.
