anyone? :)
Or are you only doing backups, no restore? :-P
gladly I just had to test disaster recovery and not actually perform it (yet) :D To be honest: I never have restored ovirt-engine with running vdsm hosts connected to it, sounds like a lot of fun, I see if I can grab some time and try this out myself :) By your description I guess you have nfs/iso domain on your engine host? why don't you just seperate it, so no need for remounts if your engine is destroyed.
