You almost certainly do not want to have 2 MON nodes in your cluster; an
odd number of nodes is strongly recommended.
(Reason: a strict majority of MON odes must be up and functional to
maintain quorum; increasing the number of MONs from 1 to 2 makes
failures more likely but does not increase resiliency.)
Cheers,
David
