Description krishnaram Karthick 2016-02-02 05:34:01 UTC 
Description of problem:

On a 16 node system, when detach tier failed on two nodes as a result of fix layout fail. Fix layout could have failed as a result of rm -rf on a directory with files and sub directories. 

Failure of fix layout shouldn't fail rebalance.

Version-Release number of selected component (if applicable):
glusterfs-3.7.5-17.el7rhgs.x86_64

How reproducible:
Yet to be determined

Steps to Reproduce:
1. On a tiered volume, have a directory with multiple subdirectories - (kernel untar for ex)
2. Issue rm -rf on this directory and start detach tier process
3. Wait for detach tier process to complete

Actual results:
Detach tier failed on two nodes and couple of files were not mobed from hot tier to cold tier

Expected results:
Detach tier should succeed on all nodes and fix layout failure should not cause rebalance to fail

Additional info:
sosreport shall be atatched
