Description

Seen in http://pulpito.ceph.com/joshd-2018-03-12_15:49:43-rados-wip-pg-log-trim-error-luminous-distro-basic-smithi/2283931/

The test does this:

    pool_a = manager.create_pool_with_unique_name(pg_num)
    manager.wait_for_clean()
    assert manager.get_num_active_clean() == pg_num

wait_for_clean() does not wait for new pools to be created on the osds, so it can return immediately, when there are 0 pgs, and the next assert will fail, as occurred here.
