Hello,

I am trying to debug a problem that has bugged us for the last few months.

We have set up a large storage system using GlusterFS, and XFS
underneath it. We have 5 RHEL6.2 servers (running
2.6.32-220.7.1.el6.x86_64 when problem last occurred), with LSI
9285-8e Raid Controller with Battery Backup Unit. System memory is
48GB.
Perhaps you should report the problem to your RedHat support
engineer and tell them to raise a bug - it's entire possible that
the RH kernel needs this fix:

be4f1ac xfs: log all dirty inodes in xfs_fs_sync_fs

Cheers,

Dave.

Ok. Is there a bug reference number or thread I can point to?

I will try to open a ticket with Red Hat.

Thanks,
...
