Hi All, Our oVirt cluster is with 3 nodes with shared fibre channel storage, the engine virtual machine is self hosted. Hypervisors OS: CentOS Linux release 7.3 / x86_64, oVirt version is 4.1.2.2. The environment has been working for about a year without any problems .
After shutdown of the hosted engine virtual machine, it doesn't start. Тhese commands that were executed: hosted-engine --set-maintenance --mode=global hosted-engine --vm-shutdown after the status of engine vm was down, we executed start. [root@alpha] hosted-engine --vm-start VM exists and is down, destroying it Exception in thread Client localhost:54321 (most likely raised during interpreter shutdown): we noticied that at vdsm.log 017-10-30 13:11:04,863+0200 INFO (jsonrpc/1) [jsonrpc.JsonRpcServer] RPC call StorageDomain.getStats succeeded in 0.26 seconds (__init__:533) 2017-10-30 13:11:05,802+0200 INFO (jsonrpc/6) [jsonrpc.JsonRpcServer] RPC call Host.getAllVmStats succeeded in 0.01 seconds (__init__:533) 2017-10-30 13:11:05,825+0200 WARN (jsonrpc/2) [virt.vm] (vmId='da98112d-b9fb-4098-93fa-1f1374b41e46') Failed to get metadata, domain not connected.

At the moment of the three nodes there is a working about 100 virtual machines and we can't manage them. Does anyone have any ideas, what can be done то recover self hosted engine virtual machine? Thahk You! Have a nice day!
