Let's verify that this is a Bluestore OSD:
| Code Block |
|---|
# ceph osd metadata 14 | grep osd_ob |
...
"osd_objectstore": "bluestore", |
Let's find the relevant devices:
| Code Block |
|---|
[root@c-osd-5 /]# ceph-bluestore-tool show-label --path /var/lib/ceph/osd |
...
/ceph-14/
infering bluefs devices from bluestore path
