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.
