Comment 1 Nir Soffer 2016-12-08 11:11:59 UTC 
This bug was opened as vdsm bug 1398822, but the root cause is ovirt-engine bug.

ovirt-engine must not deactivate the hosted engine storage domain it is running
on. Deactivating the storage domain will lead to killing the hosted engine vm.
Comment 3 Nir Soffer 2016-12-14 06:34:06 UTC 
This is a regression from earlier versions. In the past the hosted engine storage
domain was not visible in engine, so engine could not deactivate it. In version
4.0(?) we started to import the hosted engine storage domain into engine. All
the storage flows must avoid deactivation of the hosted engine storage domain.

Note that recent fix in vdsm (bug 1398822) hides this issue - even if hosted
engine storage domain is deactivated, sanlock does not kill the owner of the
leases in the storage domain. This means sanlock is accessing an inactive
storage domain, which may lead to various failures later, and is not supported.
Comment 5 Martin Sivák 2016-12-14 10:52:14 UTC 
We started importing the domain in 3.6, just fyi.

Works for me on these components on engine:

1-Deployed HE over iSCSI.
2-Added single NFS data storage domain.
3-Got hosted-storage auto-imported.
4-Tried to set hosted-storage in to the maintenance and received error as appears below:
Operation Canceled
Error while executing action: Cannot deactivate Storage. The storage selected contains the self hosted engine.

Moving to verified.
