As I mentioned in a previous post, I'm running RedHat 7.1 with the
manually patched 2.4.5 kernel and xfs-1.0.1 on a dual PII (400) with 1 Gig
of RAM. The XFS filesystems are located on a SAN RAID device accessed
through a qlogic 2100 Fibre Channel card (using the qla2x00 module provided
by Qlogic, ver 4.25). This system acts as a "gateway" by mounting the disks
from the SAN and then exporting them to an array of hosts (Solaris, IRIX,
Linux, AIX, etc) via NFS. So far, we have had a total of four system oops's.
The first oops was "unprovoked". When we rebooted, the system
generated the same oops ten minutes later. Then everything was OK. Two weeks
later, we used xfs_growfs to grow one of the partitions which worked great
(very cool). A few days later, the machine was accidentaly power cycled
(human oops). During bootup, the system oops'd when trying to mount the XFS
partition we had grown. That disk remains unmountable, and will oops any of
the three machines we have on the SAN when mounted (we had a backup of the
data and sufficient extra, so we just left this partition of death for
testing). The fourth oops just occurred today when I tried to xfsdump a
partition. I've included the ksymoops output for each of the oops's in
order.
May I suggest running xfs_repair after growing a fs. It think it sets some
of the neccesary bits right that would otherwise hamper recovery. Although
i doubt it shoold oops the box.
The first comes from the qlogic driver as it seems, may be wrong about this
one. Are there later drivers the that available? Do extensive stressing
make the box oops?
The second, I suspect you need a newer kernel with some NFS fixes. Try the
CVS tree or the 2.4.7 patch that is one the ftp site.
The third is probably related to the resize. I suggest running repair and
trying again.
The fourth is probably the nfsdeamon taking a dump in the pool again.
