There's also a parameter to the mkfs.xfs (which is what I actually meant but which is probably harder to find!) that has a similar effect but you probably need to recreate the FS. Whether this "fix" helps on existing FSs I don't know. You'll probably be better asking on the XFS lists really. -- patrick
