Hi,
I've attached a system tap script (stap -v xfs.stp) that should
hopefully print out a bit more data should the issue happen again. Do
you have a small enough number of nodes (or predictable enough pattern)
that you could run this on the nodes that tend to fail and collect the
output?
Also, could you collect an xfs_metadump of the filesystem in question
and make it available for download and analysis somewhere? I believe the
ideal approach is to mount/umount the filesystem first to replay the log
before collecting a metadump, but somebody could correct me on that (to
be safe, you could collect multiple dumps: pre-mount and post-mount).
Could you also describe your workload a little bit? Thanks.
