Hi,All.
       I do a test in glusterfs-3.3.1,but have a crash,seems return an invalid indoe or invalid inode-table in stripe_lookup_cbk.
       The test likes this:
       1. craate a dht+stripe(3) volumes.
       2.mount in three different machines
       3.mkdir testdir in mount point
       4.every machine start a postmark to craate a lot of little files named 1,2,3..... in testdir
      
       In short,three postmark process in three different machine create a lot of little files named 1,2,3,4..... in a same dir (testdir)
use a dht+stripe volumes, this crash can be reproduce.

      I used xfs as the underlying filesystem.
     I used three postmark procresses on one client or  used three postmark processes on three clients of different mathines to fopen fwrite files named (client1:a1, a2, a3, a4....  
client2:b1, b2, b3, b4....  client3:c1, c2, c3, c4...) in the same dir , They all didn't produce a crash.

      Does creating a same file in the same dir  by different client of different matchines at the same time  have any problme?

      In additionally, http://supercolony.gluster.org/pipermail/gluster-devel/2011-August/007441.html , it's decription is similar to my 
crash. How can I solve it? Look forward to your reply,Thanks.

       I have little English,sorry!
