[ovirt-users] How to re-initialize storage?

[Wood Peter]

Thank you all for the replies.

When I said "moved the VMs" I meant "rebuilt the VMs". We just created new
VMs and restored services from backups. I'm sorry for the confusion.

I followed Idan's suggestions and was able to remove the datacenter. Thank
you.
