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

I see no particular problem with this. I use DRBD -> Clustered LVM -> 
GFS2 all the time. If you wanted to add LUKS, I'd probably do it as DRBD 
-> Clustered LVM -> LUKS'ed LV -> GFS2. Note though; How will you enter 
the passphrase to mount gfs2?

This is a concern for any use of LUKS in HA. If you require a 
passphrase, automated recovery will always fail. So you have to put it 
under manual failover, which isn't very HA.

For more specific suggestions, you will need to tell us more about your 
(planned) environment.
