[ovirt-users] Problem moving master storage domain to maintenance

Hi, I have three storage domains backed by gluster in my environment (hostedstorage, data and vmstore). I would want to move the storage domains into maintenance. Have couple of questions here. 1) Will moving master storage domain into maintenance have some impact on hostedstorage? 2) I see that moving master storage domain into maintenance causes HostedEngine VM to restart and moves hosted_storage from active to Unknown state. Is this expected? 3) master storage domain remains in "Preparing for Maintenance" and i see the following exceptions in the engine.log. 2016-11-03 06:22:10,988 ERROR [org.ovirt.engine.core.vdsbroker.irsbroker.IrsBrokerCommand] (DefaultQuartzScheduler6) [2d534f09] IrsBroker::Failed::GetStoragePoolInfoVDS: IRSGenericException: IRSErrorException: IRSNoMasterDomainException: Wrong Master domain or its version: u'SD=08aba92e-e685-45d7-b03f-85d9678ecc9b, pool=581999ef-02aa-0272-0334-000000000159' 2016-11-03 06:22:11,001 WARN [org.ovirt.engine.core.bll.storage.pool.ReconstructMasterDomainCommand] (org.ovirt.thread.pool-6-thread-24) [210d2f12] Validation of action 'ReconstructMasterDomain' failed for user SYSTEM.
