I have a situation were OSDs won’t work as Docker containers with Octopus on an Ubuntu 2020.04 host. The cephadm adopt —style legacy —name osd.8 command works as expected, and sets up the /var/lib/ceph/ directory as expected: root@balin:~# ll /var/lib/ceph/c3d06c94-bb66-4f84-bf78-470a2364b667/osd.8/ total 64 drwx------ 2 167 167 4096 Jul 3 08:39 ./ drwx------ 8 167 167 4096 Jul 3 08:30 ../ lrwxrwxrwx 1 167 167 93 Jul 3 08:39 block -> /dev/ceph-590abe6f-abac-46b7-9455-80f69b63cf89/osd-block-5b229640-14e5-4e7f-9993-9368d172c30c -rw------- 1 167 167 37 Jul 3 08:39 ceph_fsid -rw------- 1 167 167 283 Jul 3 08:14 config -rw------- 1 167 167 37 Jul 3 08:39 fsid -rw------- 1 167 167 55 Jul 3 08:39 keyring -rw------- 1 167 167 6 Jul 3 08:39 ready -rw------- 1 167 167 3 May 14 21:41 require_osd_release -rw------- 1 167 167 10 Jul 3 08:39 type -rw------- 1 167 167 38 Jul 3 08:14 unit.configured -rw------- 1 167 167 48 May 14 21:41 unit.created -rw------- 1 167 167 28 Jul 3 08:14 unit.image -rw------- 1 167 167 825 Jul 3 08:14 unit.poststop -rw------- 1 167 167 2367 Jul 3 08:14 unit.run -rw------- 1 167 167 2 Jul 3 08:39 whoami However, the problem shows up when the container starts.

If I set up an OSD fresh, it works fine with the docker container until I reboot, and then I get the same permission denied error. If I use ceph-volume lvm activate a standard ceph systemd service is created, and the OSD comes online without any problem, though it’s not visible to ceph orch. _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
