Hi Alain, After looking at your logs, it's clear that the metadata on the storage domain itself says that the domain is attached to pool c58a44b1-1c98-450e-97e1-3347eeb28f86 while engine thinks the domain is attached to pool f422de63-8869-41ef-a782-8b0c9ee03c41. Can you please explain the process you used to recover from your datacenter disaster? My guess is you: 1. Reinstalled the engine host with a blank oVirt DB 2. Created a new data center 3. Created a new master domain 4. Attached some storage domains which were not attached at the time of your previous disaster 5. Tried to attach sd:d7b9d7cc-f7d6-43c7-ae13-e720951657c9 which was attached to your old storage pool at the time of the disaster. #5 failed because the metadata on the storage shows the old storage pool. At this point I see two possible options to recover your storage. PLEASE DO NOT DO ANYTHING YET (until we confirm what the best approach for recovery will be). Option 1: Use the new import storage domain feature to import this domain into your new datacenter. Option 2: Modify the storage domain metadata to remove the reference to the old storage pool. I am adding some other oVirt storage experts to the thread in order to offer you the best advice. Federico, Maor: can you offer some expert advice on this matter? I did notice this wiki page which talks about clearing the storage pool metadata from an export domain. Since this SD is iSCSI, it will be a bit more difficult to manually edit the md but I'd guess someone has a script or some instructions on how to do it. -- Adam Litke _______________________________________________ Users mailing list Users(a)ovirt.org http://lists.ovirt.org/mailman/listinfo/users
