List-Unsubscribe: , List-Archive: Be sure to do thorough testing under high load if you decide to use XFS. I currently use it for a lot of things, including NFS shares, but in some installations I've had severe data corruption. Only the latest code contains all the fixes. Release 1.1, the latest "release" code, did not work for me. It can work, and when it does it's great, but it requires a lot of good testing.
