If you retype a MA volume from one MA backend (LVM) to another MA backend(netapp) while the volume is attached only to a single instance it works fine. However if you attach the volume to a second instance this same migrations now fails, c-vol log reports a reason but if we know we can't make this work notify the user that this isn't supported. |
If you retype a MA volume from one MA backend (LVM) to another MA backend(netapp) while the volume is attached only to a single instance it works fine. However if you attach the volume to a second instance this same migrations now fails, c-vol log reports a reason but if we know we can't make this work notify the user that this isn't supported.
We get an exception on c-vol log:
