Hi kasturi,

Which version of oVirt are you using?

Apologies for the late reply. I am using the latest master.

Roy, I assume it is related to 4.0 version where the import of hosted storage domain was introduced. Care to share your insight about it?

Regards,

Maor

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.

Thanks

kasturi.
