In ceph-volume result /dev/nvme0n1p1 is for db device and in /var/lib/ceph/osd/ceph-x/ /dev/nvme1n1p1 is for db device. They are two different nvme partitions!

What do you expect here? I seem to miss the difference.
The OSDs block device is the osd-block-0c2f092a-4d92-224b0a-85e6-b65221cff791 lv
and /dev/nvme1n1p1 is used as the db volume.
