# DESCRIPTION:
|
|
# Under no circumstances when multihost is active, should an active pool
|
|
# with one hostid be importable by a host with a different hostid.
|
|
#
|
|
# STRATEGY:
|
|
# 1. Simulate an active pool on another host with ztest.
|
|
# 2. Verify 'zpool import' reports an active pool.
|
|
# 3. Verify 'zpool import [-f] $MMP_POOL' cannot import the pool.
|
|
# 4. Kill ztest to make pool eligible for import.
|
|
# 5. Verify 'zpool import' fails with the expected error message.
|
|
# 6. Verify 'zpool import $MMP_POOL' fails with the expected message.
|
|
# 7. Verify 'zpool import -f $MMP_POOL' can now import the pool.
|
|
# 8. Verify pool may be exported/imported without -f argument.
