As long as it is a reliable raid[1], you only have the same trouble as if you were working with a single spindle, i.e., if you have multiple partitions under DRBD, seek time will slow things down and you want to put each DRBD device in a separate sync-group. > 4. one of the questions that came to my boss' mind and which is > (more or less) directed to linbit: is there any guarantee that > drbd will still exist in, say, 5 to 10 years from now??
