Hello:
I have opensuse 11.2 with kernel 2.6.31.14-0.4-desktop. The system has two 160 GB Maxtor hard disks which are linked to a Silicon Image 3114 PCI SATA (soft) raid controller. They are configured as RAID1 (mirror) devices and dmraid is set up and works well except from the symptom below.
The problem is that occasionally one of the disks gives a ticking sound and this sound becomes frequent when the activity of the disks increase (eg. when copying from cd to disk).
In /var/log/messages file there are several lines like these:
Jan 14 23:43:17 linux kernel: [ 4468.814798] ata5.00: exception Emask 0x10 SAct 0x0 SErr 0x10000 action 0xe frozen Jan 14 23:43:17 linux kernel: [ 4468.814840] ata5: SError: { PHYRdyChg } Jan 14 23:43:17 linux kernel: [ 4468.814858] ata5.00: cmd c8/00:08:67:05:f4/00:00:00:00:00/e0 tag 0 dma 4096 in Jan 14 23:43:17 linux kernel: [ 4468.814860] res d0/d0:d0:d0:d0:d0/ff:ff:ff:ff:ff/c0 Emask 0x12 (ATA bus error) Jan 14 23:43:17 linux kernel: [ 4468.814878] ata5.00: status: { Busy } Jan 14 23:43:17 linux kernel: [ 4468.814887] ata5.00: error: { ICRC UNC IDNF } Jan 14 23:43:17 linux kernel: [ 4468.814904] ata5: hard resetting link
These messages occur several times in the file. I guess they have to do something with the ticks.
I had one of these a year or two ago on software raid. Not good. Make sure you have a hot spare in your raid definition. Check for a drive running hot, loose cables, etc. Are you running smartd? grep smartd /var/log/messages and look for anything other than temperature changes. If you can determine which one is doing this, you might want to add a hot spare to your raid and then use what ever raid tools you have to fail the drive or remove it, at a time of your choosing and let the system rebuild, rather than have this happen when you least expect it. -- _____________________________________ ---This space for rent--- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
