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

Absolutely not. As stated by Marcelo, your scenario does should not
require a full sync at all.

Furthermore, if your nodes *are* connected, and are both online from
pacemaker's point of view, pacemaker *will* be able to promote one of
your DRBDs and start your services.

You should share your DRBD and CRM configuration with the list, also
crm_mon and /proc/drbd output from when promotion doesn't work for you.

Finally, there will be kernel logs that indicate why DRBD wants to do a
full sync. In all, a lot of stuff, so you should put it into pastebin
and post a link to the thread.

Thanks, regards,
