[DRBD-user] DRBD primary/primary for KVM - what is the best option?

Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.


I'd be quite interested as well, obviously. So this is what we would
end up with:

Host A is primary for drbd volume 1, and secondary for drbd volume 2.
It acts as an iSCSI target for whatever's on volume 1.

Host B is primary for volume 2, and secondary for volume 1. It acts as
a target for whatever's on volume 2.

If either node fails, the opposite node takes over the secondary
volume, and exports its fallen comrade's iSCSI targets.

This idea could possibly be extended with Ben's approach of one DRBD
volume per iSCSI target. (Except that it would be in a
primary/secondary role, instead of primary/primary.) This would make
the process of rebalancing the load between the two nodes fairly
trivial.
