如果你的ceph被玩坏了 重装方式如下（清空数据）

systemctl stop ceph-mon.target
systemctl stop ceph-mgr.target
systemctl stop ceph-mds.target
systemctl stop ceph-osd.target
rm -rf /etc/systemd/system/ceph\*
killall -9 ceph-mon ceph-mgr ceph-mds
rm -rf /var/lib/ceph/mon/ /var/lib/ceph/mgr/ /var/lib/ceph/mds/
pveceph purge
apt purge ceph-mon ceph-osd ceph-mgr ceph-mds
apt purge ceph-base ceph-mgr-modules-core
rm -rf /etc/ceph/\*
rm -rf /etc/pve/ceph.conf
rm -rf /etc/pve/priv/ceph.\*
Bash

最后在 WebUI 重新配置即可
