Description Daniel Paikov 2012-06-28 10:05:35 UTC

It is currently impossible to attach V1/V2 storage domains to a V3 data center (3.1 compatibility version). This makes the domains unusable since there is no flow to upgrade unattached domains to V3.

Closing old bugs. If this issue is still relevant/important in current version, please re-open the bug.

Comment 2 Alissa 2013-08-07 13:45:33 UTC

reopening as it's still happening in 3.3

The scenario can be done in 2 ways in webadmin, in one of them it works, while it the other it doesn't.

Given a V1 unattached storage domain, and a data center of version 3.2 or 3.3 which is up:

1. working scenario- in DataCenters tab, select the data center , go to Storage subtab and press "attach Data" - the unattached V1 domain will appear there.

2. not working scenario - in Storage tab, select the V1 unattached domain, go to its DataCenter subtab, press "attach", the data center 3.2 (or 3.3) will not appear there.

(in code - StorageDataCenterListModel checks that storagedomain version == data center version - which is the wrong condition)

Unattached domains are empty by definition so just delete and recreate them.

There's no need to delete a domain (how that will help?) if it can be attached from Data Centers tab.
see above:
"working scenario- in DataCenters tab, select the data center , go to Storage subtab and press "attach Data" - the unattached V1 domain will appear there."

Also, since REST is creating the domains as V1 (see bug https://bugzilla.redhat.com/994569), if users recreate the domain with REST, it won't help deleting it because it will be created again as V1 and the attach won't work again from storage tab in UI.
