Bug#498309: xfs filesystem corruption due to attr2 bug
Package: linux-image-2.6-amd64
Version: 2.6.18+6etch3
I've lost 2 xfs filesystems this weekend after adding lots of acls to many
files.
With some help from the people of the xfs IRC channel, I could nail it down to
a problem with xfs an attr2. It seems that the debian 2.6.18 kernel is missing
a very important bugfix.
The bug report originally comes from red hat:
https://bugzilla.redhat.com/show_bug.cgi?id=212201
This is what I found in the archibes of the xfs mailing list:
http://www.linux.sgi.com/archives/xfs/2006-12/msg00104.html
The filesystems that crashed had a size of 2 TB and 6 TB. xfs_repair couldn't
help much. In the end I had to restore the data from the last backup.
I know that packages in the stable release are only updated with important
(security) fixes. But this bug can (did) cause data loss and would be worth a
fix.
