Hi,

I'm working on an embedded system running a 2.6.27-based kernel.

I'm digging into some intermittent xfs corruption issues. Yes, I realize the right answer is probably to upgrade, but for the usual embedded reasons that's tricky.

I'm seeing test xfs/182 fail with 40 or so files showing messages like:

file /opt/xfstest2/960 has incorrect size - sync failed

In our case the xfs filesystems used for testing are on top of lvm, which is in turn on top of two SAS drives in RAID1.

Any suggestions on where I should start looking? I'm looking at the "do_sync() and XFSQA test 182 failures...." thread on the mailing list from 2008, can someone point me to the commit that eventually resulted from that?

Thanks,
Chris
