| 20 | # DESCRIPTION: | |
| 21 | # Concurrent sync writes with log offline/online works. | |
| 22 | # | |
| 23 | # STRATEGY: | |
| 24 | # 1. Configure "zfs_commit_timeout_pct" | |
| 25 | # 2. Create pool with a log device. | |
| 26 | # 3. Concurrently do the following: | |
| 27 | # 3.1. Perform 8K sync writes | |
| 28 | # 3.2. Perform log offline/online commands | |
| ade306a9 | 29 | # 4. Loop to test with growing "zfs_commit_timeout_pct" values. |
