Subject [jira] [Commented] (CLOUDSTACK-6000) Volume lifecycle, stuck in expunging
Date Mon, 03 Feb 2014 00:26:10 GMT


ASF subversion and git services commented on CLOUDSTACK-6000:

Commit 631ea240f48ea7ff89bf2f611b920c5afd6b3146 in branch refs/heads/4.3 from [~mlsorensen]
[;h=631ea24 ]

CLOUDSTACK-6000: When expunging fails, move volume state back to
Destroy, so that the cleanup thread will try again on next run.
(cherry picked from commit 1aa1b3e19cfb1e06c35840d6c5bae450d9890a12)

> I think there's a hole in the volume lifecycle.  I've been noticing
> volumes lingering that should have been cleaned up, and it seems to be
> a bug in the state machine for the volumes:
>             s_fsm.addTransition(Destroy, Event.ExpungingRequested, Expunging);
>             s_fsm.addTransition(Expunging, Event.ExpungingRequested, Expunging);
>             s_fsm.addTransition(Expunging, Event.OperationSucceeded, Expunged);
>             s_fsm.addTransition(Expunging, Event.OperationFailed, Expunging);
> If a volume is in Destroy state, it goes to Expunging when the delete
> operation is requested. If the delete fails, it remains in expunging.
> The storage garbage collector will never try to clean up that volume
> again, since it only lists volumes in 'Destroy' and attempts those.
> You can only get to Expunging from Destroy, it makes sense to change
> that last line to revert the volume state back to Destroy if the
> expunge operation failed, so that it will try again next time.
