| ; Using the libaio ioengine, random write to a (zoned) block device. Write |
| ; target zones are chosen randomly among the first 128 zones starting from |
| ; device offset corresponding to the 524th zone of the device (524 x 256 MB). |
| ; For first 3 seconds, run only random write. After that, run random write job |
| ; and garbage collection simulation job in parallel. The garbage collection |
| ; simulation job runs trim workload to reset the 128 zones randomly. Use flow |
| ; option to make the zone resets happen every 128 blocks writes by the other |
| ; job. This example does not specify max_open_zones. The limit of maximum |
| ; open zones is obtained from the target block device. |
