ceph-deploy mon add ceph-mon02
ceph-deploy mon destroy ceph-mon01
追加後は、cpeh.confを同期してあげる。
ceph-deploy --overwrite-conf config push ceph001 ceph002 ceph003 ceph005 ceph006 ceph007
追加後すぐは、Prometheusに追加monの情報が入ってないので、停止・起動してあげる
ceph mgr module disable prometheus ceph mgr module enable prometheus

「public_network」を追加してあげると解決
