verified with 3.3.0.6rhs-4.el6rhs.x86_64

bug 893378 and bug 903917 working as per expectation

but 

Bug 903476 - not working as per expectation
e.g.
[root@rhsauto037 new]# cat renamefile18
cat: renamefile18: No such file or directory
[root@rhsauto037 new]# cp renamefile18 abc
cp: cannot stat `renamefile18': No such file or directory
[root@rhsauto037 new]# ls -l renamefile18
ls: cannot access renamefile18: No such file or directory
[root@rhsauto037 new]# chmod 777 f1
chmod: cannot access `f1': No such file or directory


hence moving back to assigned

sorry for the inconvenience caused, logs are attached to the bug.

After investigating the logs, it looked like a issue fixed in bug 884379.
Updated the release to

[root@localhost ~]# rpm -qa |grep glusterfs
glusterfs-devel-3.3.0.6rhs-6.el6rhs.x86_64
glusterfs-3.3.0.6rhs-6.el6rhs.x86_64
glusterfs-server-3.3.0.6rhs-6.el6rhs.x86_64
glusterfs-geo-replication-3.3.0.6rhs-6.el6rhs.x86_64
glusterfs-debuginfo-3.3.0.6rhs-6.el6rhs.x86_64
glusterfs-fuse-3.3.0.6rhs-6.el6rhs.x86_64
glusterfs-rdma-3.3.0.6rhs-6.el6rhs.x86_64


1. Create a 3 - dht volume, mount and rename file till we get a linkfile

[root@localhost export]# mount -t glusterfs localhost:/test /mnt/dht/
[root@localhost export]# cd /mnt/dht/
[root@localhost dht]# ls
[root@localhost dht]# touch 1
[root@localhost dht]# mv 1 2
[root@localhost dht]# ls -l /export/*
/export/sub1:
total 0
---------T. 2 root root 0 Mar 21 03:28 2

/export/sub2:
total 0
-rw-r--r--. 2 root root 0 Mar 21 03:28 2

/export/sub3:
total 0

2. kill brick, and check status

[root@localhost ~]# gluster volume status
Status of volume: test
Gluster process                                         Port    Online  Pid
------------------------------------------------------------------------------
Brick vm1:/export/sub1                                  24012   Y       29771
Brick vm1:/export/sub2                                  24013   N       N/A
Brick vm1:/export/sub3                                  24014   Y       29784
NFS Server on localhost                                 38467   Y       29790

3. Try to perform ops on the file.

[root@localhost dht]# cat 2
cat: 2: Transport endpoint is not connected
[root@localhost dht]# rm 2
rm: cannot remove `2': Transport endpoint is not connected
[root@localhost dht]# ls -l 2
ls: cannot access 2: Transport endpoint is not connected
[root@localhost dht]# mv 2 3
mv: cannot stat `2': Transport endpoint is not connected

Can you please rerun the test and check if the issue is fixed.

Per 04-10-2013 Storage bug triage meeting, targeting for Big Bend.

I'm not able to reproduce this bug with the glusterfs-3.4.0.9rhs-1.el6rhs.

Can you rerun this test and confirm the same?

Requesting QE to run the test as mentioned by Kaushal above.
