Yes, and I noticed that Digimer's Anvil project still uses DRBD8 as well.

If she is still using DRBD8 on her stuff, then you know that DRBD9 isn't 
fully baked yet.

That being said we use DRBD  on projects such as NFS servers and found 
it to be reliable, easy to use and useful as long as we stayed with 
active/passive.

Our experiments with active/active were very unsatisfactory. OCFS2 in 
particular was very unhappy with lots of disk i/o, even just stats. We 
tried GFS2 as well but bailed due to stability (lockup) issues (probably 
our fault, but still not worth the effort).
