Please can you confirm which version of the ceph-osd package you have installed; older versions rely on a charm shipped udev ruleset, rather than it being provided by the packaging.

Ceph OSD devices utilizing LVM volumes pointing to udev-based physical devices. LVM module is supposed to create PVs from devices using the links in /dev/disk/by-dname/ folder that are created by udev. However on reboot it happens (not always, rather like race condition) that Ceph services cannot start, and pvdisplay doesn't show any volumes created. The folder /dev/disk/by-dname/ however has all necessary device created by the end of boot process. The behaviour can be fixed manually by running "#/sbin/lvm pvscan --cache --activate ay /dev/nvme0n1" command for re-activating the LVM components and then the services can be started.
