Hi,
I'm still hoping for some help with this. Is any more information needed
in addition to the ksymoops output previously posted?
In particular i'd like to know if just remounting the filesystem (to
replay the journal), then unmounting and running xfs_repair is the best
course of action. In addition, i'd like to know what recommended
kernel/xfsprogs versions to use for best results.
I would get xfsprogs 2.9.4 (2.9.6 is not a good version with your kernel),
ftp://oss.sgi.com/projects/xfs/previous/cmd_tars/xfsprogs_2.9.4-1.tar.gz
To be on the safe side, either make an entire copy of your drive to
another device, or run "xfs_metadump -o /dev/sda1" to capture
a metadata (no file data) of your filesystem.
Then run xfs_repair (mount/unmount maybe required if the log is dirty).
If the filesystem is in a bad state after the repair (eg. everything in
lost+found), email the xfs_repair log and request further advise.
Regards,
Barry.
thanks

Presumably not - i'm using 2.6.17.11, and that information indicates the
bug was fixed in 2.6.17.7.
I've attached the output from running ksymoops on messages.1. First
crash/trace (Feb 21 19:xx) corresponds to the original XFS event; the
second (Feb 22 15:xx) is the system going down when i tried to unmount
the
volume.
Here are the additional syslog msgs corresponding to the Feb 22 15:xx
crash.
