[ovirt-users] hosted-engine storage domain locked / not recognized

I am having problems getting the hosted-engine storage domain imported into the web interface. I upgrade my hosts from el6 to el7. I am running oVirt 3.6.2 The storage domain is locked: http://screencast.com/t/gzBarFhH0 I am unable to attach in the datacenter as it says "There are no compatible Storage Domains to attach to this Data Center. Please add new Storage from the Storage tab.". I read https://bugzilla.redhat.com/show_bug.cgi?id=1269768 comment 52, and ( a little afraid to kill or loose my hosted-engine ) I destroyed the hostedengine_nfs storage. Then storage appeared again, but still the same, attach under datacenter tab does not work either. The event tab shows errors about failed adding http://screencast.com/t/49uigrvyuM3 My hosted engine storage domain is hostedengine_nfs. In https://bugzilla.redhat.com/show_bug.cgi?id=1269768 I read "ATM only domain's name 'hosted_storage' are *supported*." I found https://bugzilla.redhat.com/show_bug.cgi?id=1294457 and https://gerrit.ovirt.org/#/c/51218/ and added + ran # engine-config -s HostedEngineStorageDomainName=hosted_storage Now the storage domain is not detected in the web interface anymore. Putting storage domain name in engince-config back: # engine-config -s HostedEngineStorageDomainName=hostedengine_nfs => The domain is imported again, but locked as I started. So I wonder if it is possible to rename hosted storage domain? Or should I wait and is my described issue solved in 3.6.3?
