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.
The hosted_storage will not be picked up as a master domain. So the reconstruct must have picked up one of your other domain. I don't know why the reconstruct failed, it says here it's wrong master domain version.
Roy, when i tried to move master storage domain into maintenance i did not have any other active domains on my system other than hosted_storage. So i am not sure what reconstruct would have picked.
