In addition, you can review what is locking the drive, if anything, with
lsof (lsof /dev/...). If you boot a live CD of any distro, you will
absolutely wipe the OSD drive with wipefs -a. If you had used a WAL/DB
SSD, you need to wipe that too.
If you had used LVM for the OSDs you should delete those volume groups, for
example:
vgs|grep ceph|awk '{print $1}'|xargs -I {} vgremove -y {}
We run these procedures often and they always work.
