I seem to be stuck in a catch-22 with adding a ceph storage pool to an
existing LXD cluster.
When attempting to add a ceph storage pool, I am prompted to specify the
target node, but, when doing so, the config keys are not allowed. Once a
ceph pool is created, it's not possible to add config keys. Is there
something that I'm missing to the process of adding a ceph pool to a LXD
cluster?
The documentation and examples that I have found all assume a
stand-alone LXD instance.
Example commands that I am trying to accomplish this:
rob@stack1b:~$ lxd --version
3.13
rob@stack1b:~$ lxc cluster list
