You only have one Metadata server running and that's causing your issues here:
fsmap e64: 1/1/1 up {0=s01=up:active}
Try spawning multiple CephFS MDS servers to make your FileSystem highly available. The standby will take over once the Active one goes down.
P.S.: Removing all other lists. The ceph-users list would have been the right location for this e-mail.
