" I have a few question to do it manually: * Do I have to shutdown or live storage migrate to an other lun all my vms to perform the pv extend on the SPM? I know now it won't update the ovirt db but, is it a risk to do extend this in production? * My next question is : is it possible to fill manually the new lun size in the DB? All this would prevent me from a heavy maintenance or from a very long migration (4TB) due to maintenance mode.
