Major NFS Bugs Found & Being Fixed

Posted by Hemos on from the quashing-the-bugs dept.

mbadolato writes "From an article at kerneltrap.org: On the FreeBSD hacker mailing list, Jordan Hubbard commented on some serious issues with NFS, posting a tool called 'fsx' - originally developed for the NeXT OS - that was ideal for finding them. Matt Dillon was quite impressed by the tool and immediately started playing with it. In very little time, he presented a number of major fixes..."

There's a good collection of the emails here describing some of the fixes that Matt Dillon has made."

    Apparently Matt found one bug in the softupdates code and reported it to McKusick, who has written a patch. Matt is still testing the new code in -current and if everythings works ok it will be MFC'ed to -stable within one week, so that this code makes it for 4.5-RELEASE that is coming soon.

      Merge From Current, when a patch or new feature is tested long enough in -CURRENT the core team back ports it to -STABLE.

    It was already discussed on the kernel mailing list.
    Including a (trivial) port to GNU/Linux.
    Local filesystems are OK (except for ReiserFS), but NFS does show some problems.

  3. It also shows problems in Linux.... by pwagland · · Score: 3, Informative
    This is the linux-kernel thread.

    In essence, the problem is seen on reiserfs (being investigated) and also in NFS. No-one has mentioned following up on the NFS problems yet...

    Nor have problems yet been seen in XFS, Ext2 or Ext3.
