OK, found it.
The ExecStart line in /usr/lib/systemd/system/[email protected] is
wrong in Tentacle.
squid: ExecStart=/bin/sh -c 'timeout $CEPH_VOLUME_TIMEOUT
/usr/sbin/ceph-volume-systemd %i'
tentacle: ExecStart=/bin/sh -c 'timeout $CEPH_VOLUME_TIMEOUT
@CMAKE_INSTALL_PREFIX@/sbin/ceph-volume-systemd %i'
Obviously the @CMAKE_INSTALL_PREFIX@ isn't going to work in there...
Reinstating the line as in squid brings it back to life.

I've just upgraded a Centos 9 Stream test cluster from squid 19.2.3 to
tentacle 20.2.0. It is a non-cephadm package install. It all looked
pretty good, except that now no OSD processes start automatically
after a reboot:
* There have been no other changes whatever to the system other than
ceph.
* OSD processes would start automatically on squid.
* After a reboot, all of the /var/lib/ceph/osd/ceph-n directories
still exist but are empty.
* A manual activation brings them all back to life (sudo ceph-volume
lvm activate --all).
* Nothing at all relevant in the ceph logs.
* After a reboot, and before manually activating, /run/systemd/system
is empty. After activation all of
the /run/systemd/system/ceph-osd.target.wants symlinks are back in
place, and the /var/lib/ceph/osd/ceph-n directories have been
repopulated.
* It is happening on every osd node.
* As expected, after 10 minutes the osds are marked out (unless noout
is set).
I really can't spot what is causing this. Can anyone give me any
pointers?
Thanks, Chris
