Description
Env: my ceph cluster has tree nodes.Each node has one monitor and one mds and some osds.
test command: ceph node ls
Test steps:
1.test the command 'ceph node ls'. The output has information about the three MDSs.
2.Restart one mds.
3.stop the monitor which named mon.0.
4.So,the monitor which named mon.1 will be leader. Then, test the command 'ceph node ls'. The output just has information about two MDSs,without the mds who just restarted.

I repeat your steps, but the phenomenon is a little different. When I test the command `ceph node ls`, it only show the MDS that I just restart now. And at this time, the leader monitor and restarted mds are in same node. Then things get strange, I just recurrent one time, then I repeat about 5 times, this command's output is normal.
