Which is currently the most stable kernel that supports new-style RAID?
My system hangs for 30 seconds to 5 minutes several times a day using a
vanilla kernel 2.2.14 from ftp.kernel.org with a 2.2.14 RAID patch from
Redhat on my Debian (Potato version) server. When the system hangs, it
doesn't crash and it responds to a few basic requests ('ls' for example)
but nothing else (not even 'ls -l'). Then, it proceeds to fill the
request. I've looked through the dmesg, system and
kernel logs and have found nothing out of the ordinary. I've tried
kernel 2.2.10 with similar results.
My mdstat reads:
Personalities : [linear] [raid0] [raid1] [translucent]
read_ahead 1024 sectors
md0 : active raid1 sdb2[1] sda2[0] 8739264 blocks [2/2] [UU]
unused devices: <none>
At the same time I updated the system to Debian Potato, the new kernel
and RAID-1, I also added an Adaptec 2940U2W SCSI controller and a
matching pair of Cheetah drives, but nothing in the new hardware seems
problematic. I've got the Redhat lilo installed so that I boot the RAID
from root, and /boot directories on both disks are on separate, non-raid
partitions.
I've been using Linux for several years, but I'm unable to determine
where the problem is -- I just suspect the kernel. Any suggestions on
the most stable kernel or on how to troubleshoot this appreciated.
Also, is there any searchable archive of the linux-raid list? Wish I
would have found this list _before_ I built my raid.
Thanks,
