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:

I don't see a VG with this ID, here the IDs I see on the hosts:

Could you please repeat the command on host adm-kvmh70 ?

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.

    

    Could let me know how to remove that lun from the engine?

    

      
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.

    

    It seems that this option didn't remove the he storage information
    and that this VG is still the old one.

    

    Many thanks for your help

    Rgds,

    Arsene

    

      
Best,
