2 node cluster with a quorum device

[keithC]

with a 2 node cluster with quorum device and a shared storage such as Powerstore, does the quorum device need a connection to the Powerstore?
Has anybody run a similar configuration what are the most common pitfalls of this type of configuration?

No, the Q-device is only for voting (and only needs to be included in the corosync network).

If you are going for high-availability by way of redundancy then I think you should not go for the minimal amount of redundancy.

Yes. A PVE cluster has normally an odd number of nodes, so 3 is the minimum. Yes we all know, VMware does it with two, but any proper clustering solution does it with an odd number.
