Description Ravishankar N 2015-12-31 04:28:51 EST
+++ This bug was initially created as a clone of Bug #1293523 +++

Description of problem:

On RHEL6, we access CTR from the tier daemon using an IPC call. This is slow. It results in pause timeout when trying to create a snapshot.

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

How reproducible:

Run tier-snapshot.t test, you will see a failure.

Steps to Reproduce:

Actual results:

Fail test 12

Expected results:

Pass all

Additional info:

A fix could be to set the timeout larger on RHEL6.

    tier/snap : Adding tier-snapshot.t to bad test
    ./tests/basic/tier/tier-snapshot.t to bad test
     On RHEL6 the pause tier mechanism times out due to slow IPC calls
     between the tier daemon and brick process. A workaround may be to
     increase the timeout or improve the speed of RHEL6

    tests: add tests/basic/tier/tier-snapshot.t to bad tests
    Seems to fail a lot on the 3.7 branch as well:
    Since the test is anyway added to bad tests in master
    (http://review.gluster.org/#/c/13056/), add it in 3.7 too.
