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

If you mean that you want to preserve your existing data, then yes it's
possible. Read carefully this section in documentation:


...and specifically the section  "It is not necessary for this storage area
to be empty before you create a DRBD resource from it. In fact it is a
common use case to create a two-node cluster from a previously
non-redundant single-server system using DRBD (some caveats apply — please
refer to DRBD meta data if you are planning to do this)."
