I'm trying to build (as a proof of concept) a 2 node iPrint cluster, and since they won't be writing much data to disk I was thinking that instead of putting the iPrint data on a SAN, it could be possibile to get it to work with DRBD.

The only problem seems to be the SBD partition, since it somehow requires that both nodes mount it at the same time (which DRBD won't let me do).
Is there any workaround for this?
Does anyone have any documentation on how the SBD partition for the clustering services actually work?
