| 1 | # Example of how to split a drive up into sections, manually, and perform |
| 2 | # verify from a bunch of jobs. This example is special in that it assumes |
| 3 | # the drive is at around 30 * 124G in size, so with the below settings, we'll |
| 4 | # cover most of the drive. It's also special in that it doesn't write |
| 5 | # everything, it just writes 16k at a specific boundary, for every 128k. |
| 6 | # This is done to exercise the split path for Intel NVMe devices, most of |
| 7 | # which have a 128k stripe size and require IOs to be split if the cross |
| 8 | # the stripe boundary. |
