Ceph storage with existing Ceph pool

LXD
,
14

I did try that, however, what happens then is either:

  1. The request is sent to the API, judging by “lxd monitor --debug” but no response is sent from the daemon, so the command itself just hangs without any feedback, as a side I am unsure how long the timeout would be in such a case, but I usually give up after 10 minutes. There is no storage created. Restarting the snap.lxd.daemon.service fixes this.

  2. If 1) isn’t the case and there is no existing storage you would run the configure on the targets, then the storage create, which hangs, though this time there is a storage created with a status of “ERRORED” with the “OSD pool missing” message I provided previously. Again, the pool does indeed exist in Ceph. I did notice in the driver that it runs a query to ceph to get this information, running it manually does indeed return results:

root@node02:~# ceph --name client.lxd --cluster ceph df -f json | jq .

Where the pool we want is lxd-pool.
