You do not need a DRBD installation to access the data on the disk or
partition, since any DRBD-specific meta data is at the end of the disk
(e.g., if there is a filesystem on the disk, then it is located behind
Therefore, just mounting the filesystem from the disk or partition will
work as usual, it will just not update DRBD meta data, so DRBD would not
see any changes that you make (it would not resync automatically if you
reintegrated the disk into the NAS).
