Can I expect large delta data > replication to go equally slow using DRDB? Your drbd is set to _want_ only ~40MB/s for sync. You can: a) raise that limit temporarily with commandline calls (see the docs) b) raise that limit permanently in the config files (see the docs too) c) expect the normal replication to be faster then that (provided your network is faster) as normal replication works as fast as the connection allows. The sync is usually limited in transfer-rates so it doesn't eat all the bandwidth and leaves nothing for the already running resources (or the running of the syncing resource). - Arnold -------------- next part -------------- A non-text attachment was scrubbed...
