Hello there,
I have a SuSE Linux Enterprise Server 8.0 running XFS on
a hardware RAID 5 (SCSI) which is exporting the RAID with
NFS.
Therefore it uses the kernel based NFSd as delivered by
SuSE and I use the original kernel delivered with this
distribution.
Actually I was not able to find out the XFS Version
but it's 2.4.19-64GB-SMP Kernel and I have following
xfs packages installed: xfsprogs-2.2.1-29,
xfsprogs-devel-2.2.1-29, xfsdump-2.1.3-33.
I use xfsdump to backup the RAID and something strange
happens. During the xfsdump run there are very often
problems with nfs and the kernel throws oopses or
nfs locks up (uninterruptible sleep).
This is somehow similar to http://oss.sgi.com/bugzilla/show_bug.cgi?id=178
The server runs ext3 on his system partitions and has
nfs-utils-1.0.1-109 installed.
Perhaps you have an idea what to try or how to provide more
detailed information but as told before, the problem is not
cleanly reproducable.
