[PVE-User] Best practice for quorum device between data centers?

Well you could use a virtual quorum vm, but


dc1: 4 nodes + vm ha   dc2: 4nodes

you loose dc1 -> you loose quorum on dc2, so you can't start vm on dc2.
so it's not helping.

you really don't want to use HA here. but you can still play with "pvecm expected" to get back the quorum
if 1 dc is down.  (and maybe do dc1: 5 nodes  - dc2: 4 nodes, to avoid loose quorum on both side)


(also I don't known what is your storage ? )

hi alex, 

thanks for your response... 
that was our first idea too, but i don´t like it... 
what about the idea of a virtual quorum device (VM) inside the cluster? 
in worst case scenario (all physical connections between data centers 
are broken) where will be manual choise to start virtual quorum on this 
or that side of the cluster. Has anyone experience about this? 

regards, 
thomas
