Description spandura 2015-12-15 02:21:49 EST
Description of problem:
On a tiered volume, with 2x2 cold tier and 2x3 dis-rep hot tier was performing 
renames|deletes on files/dirs. When the bricks went offline, the renames/deletes  failed with "No such file or directory". The bricks from cold tier were all online as quorum was set. Only one of the bricks from the each sub-volume of the hot-tier went offline. 

Version-Release number of selected component (if applicable):
glusterfs 3.7.5 built on Dec  3 2015 11:30:45

How reproducible:

Steps to Reproduce:
1. Create 2x2 dis-rep cold-tier and 2x3 dis-rep hot-tier volume. Start the volume. Mount the volume. 

2. From mount, create files/dirs. 

3. rename few of the files/dirs created to different name

4. While rename is in progress, crash the mounts of the bricks using "godown" utility.(available in xfsprogs). 

Actual results:
On mount, the rename fails with "No such file or directory"

Expected results:
Renames/deletes shouldn't fail
