# DESCRIPTION:
|
|
# Ensure that the MMP thread is writing uberblocks.
|
|
#
|
|
# STRATEGY:
|
|
# 1. Set zfs_txg_timeout to large value
|
|
# 2. Create a zpool
|
|
# 3. Find the current "best" uberblock
|
|
# 4. Sleep for enough time for a potential uberblock update
|
|
# 5. Find the current "best" uberblock
|
|
# 6. If the uberblock never changed, fail
|
