Re: too few PGs per OSD (16 < min 30) but I set pool_default_pg_num: 300 in Ansible

You increased your pg_num and it finished creating them "160 active+clean".  Now you need to increase your pgp_num to match the 160 and you should be good to go.

Once those PG's have finished creating and the cluster is back to normal

How can I see Cluster migration progression?

Now I have:

# ceph status

    cluster 800221d2-4b8c-11e7-9bb9-cffc42889917
