要注意 > If you replace a dead disk with a new disk, always give it a new devid. never reuse the old devid. This is so you can replace a disk in mogilefs before all of the files from the old device have finished re-replicating.
File with active file handles (e.g. database files) Directories where many changes occur (like mail or news servers)なケースでは使わない。あとはvs.DRBD, vs.incron , vs.FUSE, vs.cron
