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

I think that will work only for the initial sync and not in this case that
data/metadata already exists on the secondary.

I believe the correct approach is to use the 'invalidate' option on the
secondary node:


Forces DRBD to consider the data on the local backing storage device as
out-of-sync. Therefore DRBD will copy each and every block from its peer,
to bring the local storage device back in sync."
