Hi there,
I'm running a CEPH cluster for some libvirt VMs and a CephFS providing
/home to ~20 desktop machines. There are 4 Hosts running 4 MONs, 4MGRs,
3MDSs (1 active, 2 standby) and 28 OSDs in total. This cluster is up and
running since the days of Bobtail (yes, including CephFS).
Might consider shutting down 1 MON, since MONs need to be in odd
numbers, And for you cluster 3 is more than sufficient.
For reasons why, read either the Ceph docs, or search this maillinglist.
Probably doesn;t help with your problem, but could you help prevent a
split-brain situation in the future.
