Description Nag Pavan Chilakam 2015-09-18 13:20:24 UTC

when detach tier is in progress, detach tier commit must not be allowed.
This was working well previously. This means it is a regression,
Could be due to fix for bz#1259694

    cluster/tier: Disallow detach commit when detach in progress
    
    1. Check if detach is running, disallow detach commit if so.
    2. Cleanup shutdown of tier daemon on detach: do not rerun fix-layout,
       do not send incorrect status back to glusterd.
