**删除文件接口集群（删除mds）** 1.停止mds进程 ~~~ [root@mytest ceph]# /etc/init.d/ceph stop mds === mds.mytest === Stopping Ceph mds.mytest on mytest...kill 9638...done ~~~ 2.将mds状态标记为失效 ~~~ [root@mytest ceph]# ceph mds fail 0 failed mds.0 ~~~ 3.删除ceph文件系统 `[root@mytest ceph]# ceph fs rm cephfs --yes-i-really-mean-it` 4.删除完了检查状态 ~~~ [root@mytest ceph]# ceph -s cluster 7e5469ac-ae1f-494f-9913-901f60c0a76b health HEALTH_OK monmap e1: 1 mons at {mytest=192.168.0.76:6789/0} election epoch 1, quorum 0 mytest osdmap e71: 2 osds: 2 up, 2 in pgmap v253: 104 pgs, 3 pools, 1962 bytes data, 20 objects 75144 kB used, 30624 MB / 30697 MB avail 104 active+clean ~~~ 可以看到已经没有了mds的那一条了
