In the interest of maintaining only one udev helper to give vdevs user friendly names, the zpool_id and zpool_layout infrastructure is being retired. They are superseded by vdev_id which incorporates all the previous functionality. Documentation for the new vdev_id(8) helper and its configuration file, vdev_id.conf(5), can be found in their respective man pages. Several useful example files are installed under /etc/zfs/. /etc/zfs/vdev_id.conf.alias.example /etc/zfs/vdev_id.conf.multipath.example /etc/zfs/vdev_id.conf.sas_direct.example /etc/zfs/vdev_id.conf.sas_switch.example Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #981

# Zpool Raid-0 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-0 configurations by adjusting the following tunables.
|
|
# For example if you wanted to create and test a single 4-disk Raid-0
|
|
# 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 \
