The issue is here:
MainThread::INFO::2016-04-27
03:26:27,185::storage_server::229::ovirt_hosted_engine_ha.lib.storage_server.StorageServer::(disconnect_storage_server)
Disconnecting storage server
MainThread::INFO::2016-04-27
03:26:27,816::upgrade::983::ovirt_hosted_engine_ha.lib.upgrade.StorageServer::(fix_storage_path)
Fixing storage path in conf file

And it's tracked here: https://bugzilla.redhat.com/1327516

We already have a patch, it will be fixed with 3.6.6

As far as I saw this issue will only cause a lot of mess in the logs
and some false alert but it's basically harmless
