Description Nag Pavan Chilakam 2015-09-22 10:50:38 UTC 
Description of problem:
========================
I issued a detach tier start and while in progress or even when the detach tier is completed, but not yet commited, I did a volume restart.
With this I expect the detach tier to continue, but I see that the detach tier has stopped and says no detach tier is in progress.

The implications are as below:
1)the user will have to re-trigger the operation of detach tier start freshly
2)As the tier deamon is started instead of reblance demon(for detaching tier), this can make promotes to hot tier and hence irritate the admin.
