Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

External meta data will speed up your system if your drbd partitions
are on one _physical_ disk and you have another one for the meta data.
Since meta data will be updated continuosly without disk caching, 
putting your meta data far away from your real data on one physical
device will just keep your disk heads busy and decrease performance.
