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 29# 4. Loop to test with growing "zfs_commit_timeout_pct" values. 30# 31 32verify_runnable "global" 33 34command -v fio > /dev/null || log_unsupported "fio missing" 35 36function cleanup 37{ 38 # 39 # Wait for any of the writes and/or zpool commands that were 40 # kicked off in the background to complete.
