- In case we deploy Ceph on a multi-node env we have
to prepare the loop devices on all nodes. For this
we moved loop devices setup to the deploy-env
Ansible role.
For simplicity we need the same device on all nodes,
so we create a loop device with a big
minor number (/dev/loop100 by default) hoping
that only low minor numbers could be busy.
- For test jobs we don't need to use different devices
for OSD data and metadata. There is no
any benefit from this for the test environment.
So let's keep it simple and put both OSD data and metadata
on the same device.
- On multi-node env Ceph cluster needs cluster members
see each other, so let's use pod network CIDR.
