# DESCRIPTION:
|
|
# dRAID should provide redundancy
|
|
#
|
|
# STRATEGY:
|
|
# 1. Create block device files for the test draid pool
|
|
# 2. For each parity value [1..3]
|
|
# - create draid pool
|
|
# - fill it with some directories/files
|
|
# - verify self-healing by overwriting devices
|
|
# - verify resilver by replacing devices
|
|
# - verify scrub by zeroing devices
|
|
# - destroy the draid pool
