I have been on XFS CVS + the patch you sent for five days now. Summary: XFS and related dcache problems (seen in ext3 too) with files that get created as symlinks to themselves or undeletable directories, or just get plain wrong permissions or ownership: These problems seem to have gone away completely. Very very nice! I still get NFS stale handle problems (the weird ones that can be worked around at times by running a ls -l on the server-side). I talked Anders (as@cohaesio.com) into testing the same kernel on another system he's running, where his main prolem were the stale handles. He too now only sees the weird stale handle problems. So, it looks like the current 2.6 status on file serving is: *) Can be done with XFS+NFS+SMP iff running a SGI kernel *) Will see weird NFS stale handle problems no matter which kernel is used Which is a lot better than the previous "2.6 will eat your files and make whatever remains owned by guest" situation :) Good work! (Any suggestions on the knfsd issue with stale handles?) -- / jakob
