Ceph/MAAS Papercuts


#1

Running into issues deploying ceph onto MAAS with 2.4.6. I’ve got the following bundle I’m attempting to deploy: https://pastebin.com/1Js4YGuM

I just swapped my osd-devices/osd-journals from charm configs to juju storage pools, and the machines in MAAS went to deploy, however juju was reporting issues finding the machines (don’t have that output, but the constraints were met).

I went to destroy my model to get a clean slate and verify things, and juju appears to be hanging while tearing down the model. Stdout is repeatedly getting: “Waiting on model to be removed, 1 application(s)…”

juju status shows: https://pastebin.com/XZysuprR, but MAAS shows the nodes as Ready.

I was pointed to: https://bugs.launchpad.net/juju/+bug/1765964
I have tried to follow the response (attempting to remove the application/individual units) without any luck.

Additionally, I had initially ran into this: https://bugs.launchpad.net/juju/+bug/1765959
I got into the current state that I am in after attempting to replicate my issue, and the deploy succeeded (first one failed similarly to the bug report).


#2

I’m using Ceph’s Charm myself with a similar setup to you, however I use charm configs rather than storage pools, and this works great for me. I’ll see if I can repro this at some point here with juju storage pools. You might need to wait a while for a Juju team response here, they’re all heads down on RC1 right now.


#3

I feel like this is a repro in itself for the initial bugs I filed some time ago mentioned above.
