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!

Yours Jia Deming
