Comment 1 Vijay Bellur 2013-10-30 04:05:45 UTC 
Can you please try by disabling open-behind? open-behind can be disabled by:

#gluster volume set d01r1 open-behind off

If this addresses the problem, a fix is available in 3.4.1.

Thanks!
I'll try "pen-behind off" and glusterfs version 3.4.1.

It solved at "open-behind off" at version 3.4.0.
