Hi all,

A while ago I had some problem with hosted-engine network which wasn't set
correctly at deploy time, so I finally decided to redeploy the hosted engine
in the hope the network will be set correctly this time. I've followed this
procedure:

Stop all VMs
Full backup of HE DB and export to safe place
Cleanup HE storage following https://access.redhat.com/solutions/2121581
Reboot Hosts
Re-deploy HE until DB recovery
Recover DB adding the following param:
 --he-remove-storage-vm             Removes the hosted-engine storage
domain, all its entities and the hosted-engine VM during restore.
 --he-remove-hosts                  Removes all the hosted-engine hosts
during restore.

Finalize HE deployment.

Everything did run without errors and I'm able to access Web UI.

But now I don't see my HE VM and its respective Storage Domain, the logs
says it isn't able to import it. I see all other SD and I'm able to manage
my VMs as before.

Please find attached engine.log

I think this is your problem:

      Thanks

Thanks for any help to resolve that issue.

I guess you can try to remove this disk/lun from the engine and let it retry.
If the only disk is of the hosted-engine, I guess it should have been
removed by '--he-remove-storage-vm' - if so, please open a bug
describing your flow in detail. Thanks.
Best,

Arsène
