# ID: zinject_003_pos
#
# DESCRIPTION:
#
# Inject an error into the first metadnode in the block
# Verify the filesystem unmountable since dnode be injected.
#
# STRATEGY:
# 1) Populate ZFS file system
# 2) Inject an error into the first metadnode in the block.
# 3) Verify the filesystem unmountable, 
#	and 'zpool status -v' will display the error as expect.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2007-02-01)
