Raid 1 - further
by Nigel Kendrick 04 Feb '05

04 Feb '05

Managed to get RAID 1 working but the sync process claimed it was going to take a serious amount of time. Looking at the stats revealed that the sync operation was running at a max of 250kB/sec which seems chronically low. Basic drive performance (hdparm) tests seemed OK so I guess the controller's not up to it? The info that came with the controller was all-but-non-existent but during a reboot I noticed that it flashed up a 'press CTRL-S to enter RAID setup' for about 1/4 sec and I managed to catch it and define card/BIOS-based RAID but this got confusing because when I restarted the server, Linux could still see 'hda' and 'hdc' rather that a single 'drive' as I expected. That's where I left it as I had to go sort out a couple of WIN2K servers (mumble mumble) with trojan infections! Next week I might try putting the drives on separate controllers again and re-setup Linux software RAID, otherwise I'll check out some of the recommendations I saw earlier for better controllers. Thanks NK

bug: comps has wrong version number
by Farkas Levente 03 Feb '05

03 Feb '05

hi, comps in rh9 is comps-9-0.20030313 while in the latest centos-3.4 it's comps-3.4centos.0-0.20050105 so the rh9 has higher version number which means this packages not upgraded during an upgrade to any version of centos. and yum also not upgrade this package. imho it's a bug. is there any way to find out what other packages is remain from some older rh version? yours. -- Levente "Si vis pacem para bellum!"

SATA - SIL3112A controller
by Nigel Kendrick 03 Feb '05

03 Feb '05

Hi folks, I have just installed a PCI SATA controller based on the SIL3112A chipset into my Centos-3 (latest kernel patches applied) system and moved an existing (not the boot disk) SATA drive from the onboard controller to the SIL-based one so I can setup software RAID with two 300GB drives. Kudzu/Linux found the controller and drives straight away and they've appeared as 'hda' and 'hdc'. I've managed to partition hdc (hda was already setup) and format it - this was VERY slow and 'top' showed a significant amount of interrupt time. A bit of Googling found the right command to enable DMA (hdparm -X66 -d1 /dev/hda etc.) and this seems to have cured that problem! While Googling I found a LOT of info on the SIL controller and Linux but it was all for various kernels and linux versions - can anyone steer me in the right direction for info on this setup with RHEL3/Centos - specifically: 1) Should I just use the native SATA drivers like I'm doing now or are there better ones to use? 2) Are there any drivers that will use the BIOS-based software RAID or is using the Linux software RAID the way to go? 3) Tweaks and recommendations for the setup would be appreciated. The system is going to be used as a backup server for bacula with various clients dumping data via 512K broadband and so the performance of the RAID system does not need to be blazingly fast - hence the I'm seeing if the cheap (£14!) controller is Ok for the job before trying anything else. Any info or pointers appreciated. Thanks Nigel Kendrick

IBM x226 lockups, convert CentOS to RHEL 3.0
by Barry L. Kline 02 Feb '05

02 Feb '05

I have a friend who has been having an intermittent problem with his nice, shiny new IBM x226 server. It's a Xeon processor, 1.5Gb RAM, hardware RAID controller running CentOS 3 The system will will sometimes run for a couple of weeks, then simply lock up -- nothing on the console, no response to pings, no "caps-lock" lights, no kernel panic indicators, nothing in the logs to indicate the problem. Other times the machine may lock up three times in one day. At the last call to me he did report that the hard drive lights flicker every once in a while during one of the systems catatonic states, but other than that there was no indication of life. We have been in contact with IBM servicce and have run their hardware tests, which perform flawlessly. We have now come to the point where they claim that "CentOS is not a supported OS" and even though they acknowledge CentOS as a RHEL clone, they argue that there is no support path for them to follow to pursue possible software problems. The system owner is ready to buy RHEL, just to get service on his machine, but I am wondering -- how difficult is it to convert from CentOS to RHEL? Is it similar to the conversion from RHEL to CentOS or from WBEL to CentOS? I would like to avoid a complete reload. Does anyone else have any suggestions? TIA, Barry
