Hello All, We had this error reported on the list about 1 or 2 months ago. During that time a lot of fixes were applied. However, we still experience this problem with the recent 2.6.31 tree. We've a
Can you try the patch below, its does two things - remove all that reclaimable flagging if we reclaim the inode directly. This removes any possibility of racing with the reclaiming thread. - adds ass

Thanks. I'll prepare a patch for upstream as the patch is extremly useful by itself. IF other issues show up I'll fix it on top of it. Unfortunately we had a crashing server last night. Please see at
Can't really see much there except some common code. Can you boot the machine with a larger console resolution (vga= kernel parameter) so a full backtrace can be captured?
Dear Christoph, Yesterday two of our servers (2.6.31.1 + your patch) crashed again, this time we have a bigger console, but not the full backtrace unfortunately. I did manage to get some more calltra
It helps a bit, but not so much. I suspect it could be a double free of an inode, and I have identified a possible race window that could explain it. But all the traces are really weird and I think o

Attached is a screendump from 2.6.32.2 with your patches (including last one) applied, but without XFS_DEBUG. We will turn on XFS_DEBUG and see if that helps. Patrick Schreurs News-Service.com JPEG i

Hello Christoph, Attached you'll find a screenshot from a 2.6.31.3 server, which includes your patches and has XFS_DEBUG turned on. I truly hope this is useful to you. Thanks again, -Patrick JPEG ima
Thanks. The patch below should fix the inode reclaim race that could lead to the double free you're seeing. To be applied ontop of all the other patches I sent you. Index: xfs/fs/xfs/linux-2.6/xfs_sy

Hi Christoph, Here are 2 more crashes with this patch applied, both having xfs_debug on and showing different traces (not inode reclaim related?). Hope it's usefull. Cheers, Tommy Attachment: sb08-20
Can't make too much sense of it, but the dir2 is something you reported earlier already. We must be stomping over inodes somewhere, but I'm not too sure where exactly. Can you try throwing the patch
No, the check is before the igrab now. That was kinda the point as I suspect that the igrab might be corrupting state of a reclaimable or in reclaim inode.
