After a bit of messing around. I managed to get it somewhat working.
If I add the osd daemons one at a time with
ceph orch daemon add osd drywood12:/dev/sda
It does actually work,
I suspect what's happening is when my rule for creating osds run and
creates them all-at-once it ties the orch it overloads cephadm and it can't
cope.
service_type: osd
service_name: osd.drywood-disks
placement:
host_pattern: 'drywood*'
spec:
data_devices:
size: "7TB:"
objectstore: bluestore
I suspect what I might need to do at least to work around the issue is set
"limit:" and bring it up until it stops working.
I did work out how to get ceph-volume to nearly work manually.
cephadm shell
ceph auth get client.bootstrap-osd -o
/var/lib/ceph/bootstrap-osd/ceph.keyring
ceph-volume lvm create --data /dev/sda --dmcrypt
but given I've now got "add osd" to work, I suspect I just need to fine
tune my osd creation rules, so it does not try and create too many osds on
the same node at the same time.
