thanks Fernando, I also use iscsi for storage domain. To remove the host from ovirt I try to put it in maintenance but returns the following error: "Error while executing action: Cannot switch Host to Maintenance mode. Host has asynchronous running tasks, wait for operation to complete and retry." any ideas? regards Il 29/06/2016 16:33, Fernando Fuentes ha scritto:
Nicola,
I guess this all boils down on the type of storage domain you have setup... If its shared than your vms will be ok. If its Local than if something goes wrong with the hosts than you could be in lots of trouble.
I went through something similar... I had to move DC (one host on the main DC) the hosts took a crap... I thought I lost everything but to my understanding the VM's are in my storage domain (iSCSI) as soon as I brought a new host online (same hostname) it all worked just fine.
My procedure was as follow:
Remove broken host from ovirt. Re-install host re add host to ovirt
Things came back online on its own... WIN :)
Regards,
