Description surabhi 2013-07-26 10:34:25 UTC

Description of problem:
Iozone gets hung when it is executed on 6x2 distributed replicate volume which is mounted via smb on a linux client.

Version-Release number of selected component (if applicable):

[root@dhcp159-0 ~]# rpm -qa | grep glusterfs
glusterfs-devel-3.4.0.12rhs.beta6-1.el6rhs.x86_64
glusterfs-debuginfo-3.4.0.12rhs.beta6-1.el6rhs.x86_64
samba-glusterfs-3.6.9-155.5.el6rhs.x86_64

glusterfs-3.4.0.12rhs.beta6-1.el6rhs.x86_64
glusterfs-geo-replication-3.4.0.12rhs.beta6-1.el6rhs.x86_64

[root@dhcp159-0 ~]# uname -a
Linux dhcp159-0.sbu.lab.eng.bos.redhat.com 2.6.32-358.14.1.el6.x86_64 #1 SMP Mon Jun 17 15:54:20 EDT 2013 x86_64 x86_64 x86_64 GNU/Linux


How reproducible:
3/3

Steps to Reproduce:
1.Do a ctdb setup.
2.create a 6x2 dis-rep volume and do a cifs mount on the client with virtual ip corresponding to the physical ip on which the volume is created.
3.Run iozone on the mount point.

Actual results:
Iozone gets hung forever.

Expected results:
Iozone should pass.

Additional info:
Running this on windows as well. taking too long not yet passed. Will post the results.
