[ceph-users] block.db symlink missing after each reboot

Hi there, i've a bunch of hosts where i migrated HDD only OSDs to hybird ones using: sudo -E -u ceph -- bash -c 'ceph-bluestore-tool --path /var/lib/ceph/osd/ceph-${OSD} bluefs-bdev-new-db --dev-target /dev/bluefs_db1/db-osd${OSD}' while this worked fine and each OSD was running fine. It looses it's block.db symlink after reboot. If i manually recreate the block.db symlink inside: /var/lib/ceph/osd/ceph-* all osds start fine. Can anybody help who creates those symlinks and why they're not created automatically in case of migrated db? Greets, Stefan
