Ok, just gave it a try and I am still running into an error. Here is exactly what I did: I logged on to my host where osd.10 is Deleted my current VG and LV's on my NVME that will hold the WAL/DB, as I kind of liked what you used. My VG is called "cephdb03" and my LVs are called "ceph-osd-dbX", where "X" is 1 through 4. Ran the command to stop osd.10 service: systemctl stop ceph-474264fe-b00e-11ee-b586-ac1f6b0ff21a@osd.10 connected to the general cephadm shell and ran: ceph-volume lvm activate --all --no-systemd Exited the general shel and entered the container for OSD 10: cephadm shell name osd.10 Ran the ceph-volume command to create the new DB on cephdb03/ceph-osd-db1 : ceph-volume lvm new-db --osd-id 10 --osd-fsid 474264fe-b00e-11ee-b586-ac1f6b0ff21a --target cephdb03/ceph-osd-db1 Got the following error: --> Unable to find any LV for source OSD: id:10 fsid:474264fe-b00e-11ee-b586-ac1f6b0ff21a Unexpected error, terminating _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
