write a manypools teuthology task
Write a teuthology task that creates lots of pools:
tasks: - manypools: num_of_pools: NUM - radosbench:
The task would create NUM pools, each with a single dummy object (to enforce pools to exist on PGs). Then the yaml can run radosbench as the next task.

Running final tests now, but this appears to be working properly. Which is odd since it seemed broken before, but maybe I misread the information I was getting. Trying it on a 10k pool create now, anyway, so that ought to turn up any issues.
#10 Updated by Greg Farnum over 8 years ago
- Subject changed from qa: find out max pools per osd (without running out of RAM, without degrading performance) to write a manypools teuthology task
- Status changed from 7 to Resolved
So each pool is actually 8 PGs each by default, so the task just writes 16 1-byte objects to each pool using rados bench.
