Description Dan Lambright 2015-12-22 02:53:46 UTC

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:
1.
2.
3.

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
