Ya, I think it might work as long as the exports are different on each nodes. In
that case, it might be more efficient to have 2 DRBD ressources attached to each
one of the two nodes, and a special pacemaker/hb RA that can handle add/remove
from /etc/exports. The problem I can see will be to remove a mount point from
/etc/exports when there are open files. If you failover the entire NFS server,
you can easily 'kill -9' the server in order to stop it.
