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.
Mit freundlichen Grüßen / Best Regards
Robert Köppl
