Hi,

Recently I was created BZ for librbd [1], closed as won't fix. So, still impossible even upgrade RBD driver without reboot. Typical misunderstanding between developers and operations

Good evening everyone!

Guys, I managed to raise the RBD through Cinder without problem. Everything works, including removing the Storage Domain (through postgres).

The initial objective was to go up with RBD Mirror but I'm not succeeding, because Cinder is connecting the volume through KRBD, it doesn't support Journaling which ends up breaking the Mirror...

Is there any way/configuration for Cinder to start the machine using librbd instead of KRBD? Because in my scenario we have to use Mirror.

Thanks in advance.
