[ovirt-users] Re: Move Hosted Engine VM to a different storage domain

Hi, Thank you for the reply. I am building another environment today, so I will run through the backup and restore again. I do recall one issue I had with the restore was that it gave an error that one of the storage domains were already in use. This was a new storage domain I added, with no VMs on. I just want to make sure, I probably cannot deploy the HE on a storage domain that is in maintenance, correct? I will try and create a new storage domain again, but remove it from the data center, and perhaps see if the HE will deploy to it.

The main goal was to have no downtime, but if it is going to be too complex, I think my next option will be to create a new HE, and attach the current storage domains. Obviously it is going to take a bit of planning, as I will need to configure all the networks etc. from scratch again.
