Stale file handle with FUSE client

    Hi, all.

    
    I am having a problem on my replicated setup where files which are
    commonly accessed from different clients (such as ~/.Xauthority) are
    returning "Stale file handle" warning and subsequent errors.  Access
    isn't necessarily concurrent, but within a minute or two.

    
    In this case, trying to log in with `ssh -X` to a few compute nodes
    in our cluster, after the second or third time I see these in the
    client's log file:

      /aorth/.Xauthority => -1 (No such file or directory)

    
    And I've seen the issue happen also when accessing other shared
    files within small time spans, like ~/.cpan/CPAN/MyConfig.pm.  Other
    times I don't see any entries in the log file at all...

    
    The volume in question (homes) is configured like this:

    # gluster volume info homes

       
      Volume Name: homes

      Type: Replicate

      Volume ID: 38637fa1-7ef3-4e8d-ace9-8ff81bc8bed9

      Status: Started

      Number of Bricks: 1 x 2 = 2

      Transport-type: tcp

      Bricks:

      Brick1: storage0:/mnt/gfs/storage0/sda1/homes

      Brick2: storage1:/mnt/gfs/storage1/sdb1/homes

      Options Reconfigured:

      nfs.disable: on

      
    Clients and servers are all running GlusterFS 3.4.2 on CentOS 6.4/5.

    
    Thanks,
