Does anyone know if the combination of LVM2 and software RAID5 on top
of SATA works reliably outside of any filesystem issues?
We are running a debian woody box, with some things from backports; its
got 2.6.6 kernel, LVM2, sata, software raid 5 and many of its
filesystems are XFS.
We've been seeing lots of problems on the XFS partitions, but
touching /forcefsck and watching a reboot reveals that there are
frequently problems with other filesystems; / frequently has issues and
its ext2 on /dev/hda1 which is a PATA device.
XFS certainly complains a lot louder than the other filesystems do when
it has problems, but I don't believe that its an XFS specific problem.
What SATA controller are you running? I think I've traced my problems
to the Silicon Image 3112 controller. There are known problems with
this chip which look like they have been fixed, but only if you apply
all of the latest patches (latest from 6/22:
I'm waiting on a new SATA controller so I can start testing again and
see if that's my only problem.
