Hello. This mail is a follow up of a message on XFS mailing list. I had hang with 3.6.1, and then , damage on XFS filesystem.

3.6.1 is not alone. Tried 3.6.2, and had another hang with quite a different trace this time , so not really sure the 2 problems are related . Anyway the problem is maybe not XFS, but is just a consequence of what seems more like kernel problems.

Well. at least, after the hard reset, xfs volume was still good this time.

Old mail (send to xfs mailing list) for reference :

Hello,
Last week, I encountered problems with xfs volumes on several machines. Kernel hanged under heavy load, I hard to hard reset. After reboot, xfs volume was not able to mount, and xfs_repair didn't managed to recover the volume cleanly on 2 different machines.

Just to relax things, It wasn't production data, so it don't matter if I recover data or not. But more important to me is to understand why things went wrong...

I'm using XFS since a long time, on lots of data, it's the first time I encounter such a problem, but I was using unusual option : filestreams, and was using kernel 3.6.1. So I wonder if it has something to do with the crash.

I have nothing very conclusive in the kernel logs, apart this :
