Unable to detach ISO storage domain from all Data Centers

Solution Unverified - Updated -

Issue

  • ISO Storage Domain is put in "maintenance" on 9 data centers
  • I can detach the ISO storage domain correctly from our primary data center (where Hosted Engine runs)

  • Detaching from any other data center fails with the error:

VDSM command DetachStorageDomainVDS failed: Storage domain not in pool: u'domain=1a003ead-5f64-4acb-81a3-fab35e0e92ea, pool=12a39c44-6603-4b60-878b-45e75805e22f'

  • After this, the storage domain cannot be activated for that data center any more until the SPM for that data center has been changed. However, when put into maintenance mode, it still cannot be detached.
