清理删除 cephfs
关闭所有mds服务
systemctl stop ceph-mds@$HOSTNAME
systemctl status ceph-mds@$HOSTNAME
查看cephfs 信息
## ceph fs ls
name: leadorfs, metadata pool: cephfs_metadata, data pools: [cephfs_data ]
## ceph mds stat
e392: 0/1/1 up, 1 failed
## ceph mon dump
dumped monmap epoch 1
设置mds状态为失败
ceph mds fail 0
删除mds文件系统
ceph fs rm leadorfs --yes-i-really-mean-it
删除元数据文件夹
ceph osd pool delete cephfs_metadata cephfs_metadata --yes-i-really-really-mean-it
ceph osd pool delete cephfs_data cephfs_data --yes-i-really-really-mean-it
再次查看集群状态

重建 cephfs
启动所有mds服务
systemctl start ceph-mds@$HOSTNAME
systemctl status ceph-mds@$HOSTNAME
#验证:
ceph mds stat
e397:, 3 up:standby
重建cephfs
ceph osd pool create cephfs_data 512
ceph osd pool create cephfs_metadata 512
ceph fs new ptcephfs cephfs_metadata cephfs_data
验证集群状态
