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

Within DRBD?  No.  That's not DRBD's job.  That job is best handled by
something like Nagios.  Nagios is a bit heavyweight for *just* monitoring
DRBD, but if you have ~70 machines all running various services, Nagios can
make your life a hell of a lot easier.  If you just want to monitor DRBD sync
status, put together a shell or Perl script that runs on both nodes every 10
min via cron and mails a list of people when /proc/drbd matches
/SyncSource|SyncTarget/ .  You can search for "check-drbd" to find a Nagios
plugin that does that; modify it for your needs.

Which HA system are you talking about?  Pacemaker, Corosync, heartbeat?  The
answer to this will almost certainly be found in the Fine Manual for the HA
system you're using.
