The difference seems to be that with test_rebuild_server, the failure is "Current status: REBUILD. Current task state: rebuilding." and with the rebuild from error it's "Current status: ERROR. Current task state: rebuilding.". Either way they are just timing out in the rebuild, so the root cause is probably the same.
