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

[knarra]

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.
