根据osd的id定位物理磁盘

方式一：根据osd的fsid进行查找

# 1、先定位osd在哪一个host上

# 2、在对应host上查看osd对应的fsid
root@pve-ceph01:~# cat /var/lib/ceph/osd/ceph-0/fsid 
be5ea6c8-06f6-45de-ad1d-5616a8723882

# 3、根据查询得到的fsid 与lsblk中的信息进行对比
root@pve-ceph01:~# lsblk

方式二：ceph-volume lvm list 9

# 注意用法
ceph-volume lvm list 9            #这个数字9表示osd的id
ceph-volume lvm list /dev/vdb     #也可以指定磁盘查看是那个osd

root@pve-ceph01:~# ceph-volume lvm list 9
====== osd.9 =======

  [block]       /dev/ceph-4597d1b3-8f62-4791-b6c2-4d459167fdee/osd-block-273c0d18-4586-4655-977f-d6f3fddbea99
