68 1. create pool.a with pg_num=1, size=2
69 pg will be mapped to osd.0, and osd.1, and it should be active+clean
70 2. create pool.b with pg_num=1, size=2.
71 if the pgs stuck in creating, delete the pool since the pool and try
72 again, eventually we'll get the pool to land on the other 2 osds that
73 aren't occupied by pool.a. (this will also verify that pgs for deleted
74 pools get cleaned out of the creating wait list.)
75 3. mark an osd out. verify that some pgs get stuck stale or peering.
76 4. delete a pool, verify pgs go active.
