Hello, I'm trying to decommission the old master storage domain in ovirt, and replace it with a new one. All of the VMs have been migrated off of the old master, and everything has been running on the new storage domain for a couple months. But when I try to put the old domain into maintenance mode I get an error. Old Master: vm-storage-ssd New Domain: vm-storage-ssd2 The error is: Failed to Reconstruct Master Domain for Data Center EDC2 As well as: Sync Error on Master Domain between Host daccs01 and oVirt Engine. Domain: vm-storage-ssd is marked as Master in oVirt Engine database but not on the Storage side. Please consult with Support on how to fix this issue. 2021-07-28 11:41:34,870-07 WARN  [org.ovirt.engine.core.vdsbroker.irsbroker.IrsProxy] (EE-ManagedThreadFactory-engine-Thread-23) [] Master domain version is not in sync between DB and VDSM. Domain vm-storage-ssd  marked as master, but the version in DB: 283 and in VDSM: 280 And: Not stopping SPM on vds daccs01, pool id f72ec125-69a1-4c1b-a5e1-313fcb70b6ff as there are uncleared tasks Task '5fa9edf0-56c3-40e4-9327-47bf7764d28d', status 'finished' After a couple minutes all the domains are marked as active again and things continue, but vm-storage-ssd is still listed as the master domain. Any thoughts?
