When using a version of ceph-disk which contains the change [1] to enable --runtime for ceph-osd systemd units, directory-backed OSDs do not start on boot. If I modify the same system to use disk-backed OSDs then I do not have this problem. How to reproduce: - Deploy a directory-backed OSD - Observe on first boot, on an OSD node, that OSDs are running but that their target is in /run not /etc, which will cause them to not start on reboot if they are directory-based [2] - Reboot the system and observe that the OSDs are not running Workaround: Replace ceph-disk's main.py with the version [3] that proceeded the --runtime change [1] (and python -O -m compileall /usr/lib/python2.7/site-packages/ceph_disk/).

I confirm that https://github.com/ceph/ceph/pull/14546 fixes the problem. Thank you
John, QE would like your help in testing this fix. Can you do that?
I have empirically tested that the patch fixes the bug with the following process: - Apply the patch [1] - Deploy a directory-backed OSD - Observe on first boot, on an OSD node, that OSDs are running and that their target is in /etc not /run (so they _should_ restart on reboot) - Reboot the system and observe that the OSDs _are_ running [1] Details on how patch was applied: pushd /usr/lib/python2.7/site-packages/ceph_disk/ mv main.py /root/ceph-disk-main.py curl https://raw.githubusercontent.com/ceph/ceph/f425a127b7487d2093c8c943f0bcdec3d673d601/src/ceph-disk/ceph_disk/main.py > main.py popd python -O -m compileall /usr/lib/python2.7/site-packages/ceph_disk/
