#
# DESCRIPTION:
#	A mirrored pool can withstand N-1 device are failing or missing.
#
# STRATEGY:
#	1. Create N(>2,<5) virtual disk files.
#	2. Create mirror pool based on the virtual disk files.
#	3. Fill the filesystem with directories and files.
#	4. Record all the files and directories checksum information.
#	5. Damaged at most N-1 of the virtual disk files.
#	6. Verify the data are correct to prove mirror can withstand N-1 devices
#	   are failing.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2006-08-21)
