Regarding huge volumes, the most obvious one is reaching the size limit, which is currently 1 PiB. But there are other limitations as well, e.g.: - a single huge volume limits the setup to a single DRBD resource, which limits the setup to a single replication link - same for disk backends, with multiple DRBD volumes, there can be multiple independent backends (even different storage pools, e.g. a larger/slower/cheaper one for the long term archive and a smaller/faster/more expensive one for the currently running jobs) - if a full sync is required for whatever reason, it takes a very long time and always affects all data areas (or in this case, projects) - same for verify A setup with multiple resources is often more flexible and easier to maintain than one with a single huge volume in a single resource. br, Robert _______________________________________________ drbd-user mailing list [email protected] http://lists.linbit.com/mailman/listinfo/drbd-user
