[ovirt-users] Re: Restoring hosted engine from backup fails on new FC storage domain creation

I found these using dmsetup ls -tree: 6db20b74--512d--4a70--994e--8923d9e1e50b-master (253:21) └─36000d31005b4f6000000000000000029 (253:36) ├─ (65:64) ├─ (65:80) ├─ (65:32) └─ (65:48) 6db20b74--512d--4a70--994e--8923d9e1e50b-inbox (253:17) └─36000d31005b4f6000000000000000029 (253:36) ├─ (65:64) ├─ (65:80) ├─ (65:32) └─ (65:48) db64924d--aa94--48ad--809a--3d235e84686b-ids (253:22) └─36000d31005b4f600000000000000001d (253:12) ├─ (8:112) ├─ (8:96) ├─ (8:64) └─ (8:48) df259f5a--e1bd--4a93--bd6e--bace450625dc-master (253:35) └─36000d31005b4f600000000000000001a (253:13) ├─ (8:144) ├─ (8:128) ├─ (8:80) └─ (8:32) 6db20b74--512d--4a70--994e--8923d9e1e50b-outbox (253:18) └─36000d31005b4f6000000000000000029 (253:36) ├─ (65:64) ├─ (65:80) ├─ (65:32) └─ (65:48) ID matches the one in ansible error and vdsm log. Are these done by oVirt? I mean it's pretty hard to know what to free if you don't know what should be and should not be there. And if these can be cleared how do you do that?

By the way does anyone know how I can connect back to that HE that is hosted locally during installation (URL like https://ovirt02.virt.local:6900/ovirt-engine/). It seems the connection disappeared this morning. Now I'm totally blind what's going on in both nodes... Maybe I have to clear this SHE recovery and start from the scratch.
