Hi

We must move the hosted engine disk from the storage where it was installed, to another one, due to storage maintenance activities.

Both current and future volume are hosted on FC storage.

It is possible to perform this change without interrupting services ? it is a secure change ?

Current setup:

Four nodes Centos 7.2.1511

Vdsm 4.18.9.1

Libvirt 1.2.17.13

KVM 2.3.0-31

oVirtEngine 4.0.1.1-1.el7.centos.

Thanks in advance sur any suggestion.

Honestly I never tested it so I'd suggest to properly try it on a test env, but on FC we are not going to connect a storage server since the device are already configured on the host.

So as you correctly move the whole storage domain on a different LUN, I'd expect that ovirt-ha-agent and the engine will simply found the same storage domain.

I don't think you can do it keeping the engine online.
