Similar, but not the same.
Cman and Pacemaker both use corosync for inter-node communication
which IIRC, limits message sizes to 1Mb.

I don't know about cman, but Pacemaker also compresses large messages
before giving them to corosync.
So in practice we can send configurations up to 20Mb or so over the
wire (its XML which compresses very well).
