40#
41# DESCRIPTION:
42# 	Once a pool has been exported, and one or more devices are
43#	damaged or missing (d/m), import should handle this kind of situation
44#	as described:
45#		- Regular, report error while any number of devices failing.
46#		- Mirror could withstand (N-1) devices failing
47#		  before data integrity is compromised
48#		- Raidz could withstand one devices failing
49#		  before data integrity is compromised
50# 	Verify those are true.
51#
52# STRATEGY:
53#	1. Create test pool upon device files using the various combinations.
54#		- Regular pool
55#		- Mirror
56#		- Raidz
57#	2. Create necessary filesystem and test files.
58#	3. Export the test pool.
59#	4. Remove one or more devices
60#	5. Verify 'zpool import' will handle d/m device successfully.
61#	   Using the various combinations.
62#		- Regular import
63#		- Alternate Root Specified
64#	   It should be succeed with single d/m device upon 'raidz' & 'mirror',
65#	   but failed against 'regular' or more d/m devices.
66#	6. If import succeed, verify following is true:
67#		- The pool shows up under 'zpool list'.
68#		- The pool's health should be DEGRADED.
69#		- It contains the correct test file
70#
71# TESTABILITY: explicit
72#
73# TEST_AUTOMATION_LEVEL: automated
74#
75# CODING_STATUS: COMPLETED (2005-08-01)
