# Zpool Raid-10 Configuration
#
# This script is used to test with the /dev/disk/by-vdev/[A-Z][1-n] devices.
# It assumes that you have already populated /dev/disk/by-vdev/ by creating
# an /etc/zfs/vdev_id.conf file based on your system design.
#
# You can then use either the zpool-create.sh or the zpios.sh test script to
# test various Raid-10 configurations by adjusting the following tunables.
# For example if you wanted to create and test a single 4-disk Raid-10
# configuration using disks [A-D]1 with dedicated ZIL and L2ARC devices
# you could run the following.
#
# ZIL="log A2" L2ARC="cache B2" RANKS=1 CHANNELS=4 \
# zpool-create.sh -c zpool-raid10
#
# zpool status tank
#   pool: tank
#  state: ONLINE
#  scan: none requested
# config:
