rhevm.log

The fix to bug #728990 seems to have created or exposed a new bug.

* NFS DC with 2 data domains on 2 storage servers.
* Block master data domain with iptables.
* Reconstruct is run on the 2nd domain.
* When reconstruct is finished, RHEVM disconnects the new master. Both domains are marked as Inactive and the DC is marked as Maintenance.
Comment 1 Daniel Paikov 2011-08-23 14:11:11 UTC 
Moving to VDSM. The problem is that VDSM is falsely reporting the non-problematic NFS domain as having zero free space:

f3d42d46-b9f2-4e42-88b5-fd53a2a7af1f = {'status': 'Active', 'diskfree': '0', 'disktotal': '0'}
