Hi! We re using external Metadata on clusters where we replicate large storages connected to the nodes via Fibre channel. There are two reasons for that: 1: Luns and arrays on the storage are optimised for different access patterns and sizes, preferred paths are set in a way, that different controllers are used, so metadata and application data do not compete for the data 2: snapshots of the luns can be used for backup/testing environments without having to bother with DRBD-metadata on them, as long as they are created when in a consistent state 3: in case of a meltdown of both servers we can get it up and running for emergency-production without needing to configure a cluster at all Of course this is not a typical drbd deployment.
