Description Daniel Paikov 2011-12-12 11:07:05 UTC 
* Pool with several domains.
* Deactivate all domains, including master.
* Try to remove DC.
* Failure on VDSM side because it can't find some of the domains, even though they all exist.

It is not surprising that you are unable to perform a pool operation without an active master domain. The error message could have been prettier, though.
Comment 5 RHEL Program Management 2012-05-04 04:04:52 UTC 
Since RHEL 6.3 External Beta has begun, and this bug remains
unresolved, it has been rejected as it is not proposed as
exception or blocker.

Red Hat invites you to ask your support representative to
propose this request, if appropriate and relevant, in the
next release of Red Hat Enterprise Linux.
Comment 7 Ayal Baron 2012-08-15 07:29:45 UTC 
Sounds to me like the issue is that engine disconnected the host from the storage and it cannot reach any of the domains.
If this is correct then this is an engine bug.
Comment 8 RHEL Program Management 2012-12-14 06:56:08 UTC 
This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.
