Comment 6 for bug 1492742

I have a clean deployment of openstack using autopilot. I've deployed using ceph for both object and block storage, and this bug rears its head. I have a 3 storage node stack with 2 usable ceph drives per node. I'm curious on how might I temporarily get around this error by increase the max PG Number in which the warning is flagged. It's mentioned by in post #3, however, I'm unable to set it using juju. Placing it directly in the ceph.conf doesn't work as it won't persist.

'mon pg warn max per osd = 500'
