However, having been served so well by DRBD in the last 4 years, I am somewhat reluctant to abandon it for another, probably not so battle-tested, technology. In particular, it seems that to be useful (ie: stable enought) for VM disk storage, Gluster need a 3-way cluster and sharding enabled (which I would like to avoid). In contrast, DRBD + GFS2 (or DRBD + LVM) can be used in a 2-way cluster without problem.
