Jump into your mysql cloud db. Run this: select op.id, name, total_capacity from op_host_capacity op, host h where op.capacity_type=0 and op.host_id=h.id; (my example output from a test cloud) +----+-------------+----------------+ | id | name | total_capacity | +----+-------------+----------------+ | 8 | node0.cloud | 50373124096 | | 10 | node1.cloud | 50373124096 | +----+-------------+----------------+ 2 rows in set (0.00 sec)
After, just run an update to double up the capacity for each host you want to over-commit. Example: update op_host_capacity set total_capacity=50373124096 where id=8; update op_host_capacity set total_capacity=50373124096 where id=10; Note: I've already doubled up the capacity on these boxes.
