Expected results: Not used devices should be ignored. Additional info: See depends.
1) what does it mean not used? 2) please attach full logs (SOS report), we need to see the removeStorageDomain and disconnectStorageServer commands 3) reducing severity since I don't see any functional impact on the user
Wrt vdsm going on working while there are failed devices, that will be taken care of by bug 880738 Wrt the log containing messages about devices which are failing, that we are not going to remove as this information is needed many times to diagnose problems. *** This bug has been marked as a duplicate of bug 880738 ***
