Hi Manual,
This is a well known issue. You are definitely not the first one to hit this
problem. Before Jewel i (and other as well) added the line
ceph-disk activate all
to /etc/rc.local to get the OSD’s running at boot. In Jewel, however, this
doesn’t work anymore. Now i add these line to /etc/rc.local
for dev in $(ceph-disk list | grep "ceph journal" | awk '{print $1}')
do
ceph-disk trigger $dev
done
The OSD’s are now automatically mounted and started. After this, the systemctl
commands also work.
