I'm coming in late so I don't know the whole story here, but that name's indicative of a Managed (containerized) resource. You can't manually construct, delete or change the systemd services for such items. I learned that the hard way. The service declaration/control files are dynamically created by Ceph under /var/run or something like that and they don't survive reboots. I expect that something similar applies to /dev items, Certainly I've created my share of /dev USB devices dynamically via the udev hot-swap subsystem. What might help is to look at what's under /var/lib/ceph-3b5662ac-854a- 4954-aa44-8951feaa1840. The resources defined there seem to be the prime sources used to generate dynamica services.

Hi more info,
The ceph-volume lvm list, show the wrong osds for example:
====== osd.82 ======
[block] /dev/ceph-3b5662ac-854a-4954-aa44-8951feaa1840/osd- block-f96c826d-3570-4c78-9ef6-bea191589102
block device /dev/ceph-3b5662ac-854a-4954-aa44- 8951feaa1840/osd-block-f96c826d-3570-4c78-9ef6-bea191589102 block uuid avfhQj-uiRt-ZwjG-4jkD-G4tg-a3BM- bcbUfc cephx lockbox secret cluster fsid 6f5a65a7-316c-4825-afcb-428608941dd1 cluster name ceph crush device class encrypted 0 osd fsid f96c826d-3570-4c78-9ef6-bea191589102 osd id 82 osdspec affinity type block vdo 0 devices /dev/mapper/mpatha
the /dev/mapper/mpatha is linked to dm-29. The path ceph-3b5662ac-854a-4954-aa44-8951feaa1840/osd-block- f96c826d-3570-4c78-9ef6-bea191589102 does not exits
I just try to create the path and link to dm-29: ln -s ceph-3b5662ac-854a-4954-aa44-8951feaa1840/osd-block- f96c826d-3570-4c78-9ef6-bea191589102 ../dm-29
and reboot, but the path has disappear again
Any advice is welcomed. Regards, I
