http://wiki.linux-ha.org/DRBD/FAQ has just been updated.

BTW, let me remind all of you to review the
http://www.drbd.org/users-guide/
so we can make incorporate any suggestions/corrections in time.

We will then put it online properly,
maybe even add a "comment" feature online.

And we will complement with cheat-sheet, and a more recent FAQ
(yet to be compiled, suggestions welcome),
which will then become the authoritative DRBD FAQ.

cheers,
