# DESCRIPTION:
|
|
# Concurrent sync writes with log offline/online works.
|
|
#
|
|
# STRATEGY:
|
|
# 1. Configure "zfs_commit_timeout_pct"
|
|
# 2. Create pool with a log device.
|
|
# 3. Concurrently do the following:
|
|
# 3.1. Perform 8K sync writes
|
|
# 3.2. Perform log offline/online commands
|
|
# 4. Loop to test with growing "zfs_commit_timeout_pct" values.
|
