[ceph-users] mon vanished after cephadm upgrade

I had a 3 mon CEPH cluster, after updating from 15.2.x to 16.2.x one of my mon's is showing as a stopped state in the Ceph Dashboard.And checking the cephadm logs on the server in question I can see "/usr/bin/docker: Error: No such object: ceph-30449cba-44e4-11eb-ba64-dda10beff041-mon.sn-m01"There is a few OSD services running on the same physical server and they all are starting/running fine via docker.I tried to do a cephadm apply mon to push a new mon to the same host, but it seems to not do anything, nothing shows in the same log file on sn-m01Also ceph -s shows full health and no errors and has no trace of the "failed" mon (not sure if this is expected), only in the ceph dashboard under services can I see the stopped not running mon.
