I need to start deploying some large XFS based fileservers servers and wish to try a kernel newer than what we've been using (2.6.38.5 from kernel.org). We've stayed at 2.6.38.5 for awhile, but have had metadata loss on many shutdowns, clean or not. We've found 0 length files where the files had been written and closed long before the crash - in some cases we were careful sync by hand, wait for quiescent drives, then clean reboot, etc. This sounds related to a series of commits that indicates some workarounds and fixes in the time frame of 2.6.38.5 to 3.0 (how completely this particular problem was fixed, I don't know). Several past threads here on this list have described these servers, but they are 126 2TB drive RAID 60 used for mostly genetic sequencing data. Christoph recently suggested here in another xfs developer list thread: "I've also backported it to the 3.0-stable issues. I would recommend to upgrade to the latest Linux 3.0-stable release, as I'll plan to backport all important XFS fixes to it." Is this a decent target for us to try? We're looking for the best XFS and NFS stability that is practical.
