I was trying to remove the (mon-node) without replacing it.
What really happen is this, I was adding a new mon-node after an initial successful cluster setup with one mon-node
but addition was not successful and it already affected the monmap, trying to remove with "ceph mon remove" or ceph-deploy mon destroy" are not successful.
Also, when I removed the bad mon-node from the extracted monmap, the print was fine then I injected it but "ceph mon dump" after starting the mon with "start ceph-mon" is still showing the old monmap not the newly injected.

Hi Sunday,
~Brian
did you verify the contents of your monmap? In general, the procedure might look something like this:
- ceph-mon -i <id> --extract-monmap /tmp/monmap
- monmaptool --print /tmp/monmap
- monmaptool --rm <old_mon_id> --add <new_mon_id> <new_mon_ip_and_port> --clobber /tmp/monmap
- monmaptool --print /tmp/monmap
at this point, the monmap should look as you intend it to, with the old monitor removed and new monitor properly listed. Stop all ceph monitor daemons and inject the monmap to each one, then start them.
- stop ceph-mon
- ceph-mon -i <id> --inject-monmap /tmp/monmap
- start ceph-mon
