Nothing there is as attractive as a simple (self healing) quorum system that works over encrypted WAN links. No quorum = down. Else, it works. We have no STONITH, we have no redundant network links. Thus the typical stuff that seems to be used (DRBD) and even the future postgres stuff (postgres r and xc) do not appear like strong candidates.

you would use the quorum system to control the DRBD of postgres stuff.

this is available today with the linux-ha project.

Thanks. The quorum server looks promising.
