# Description
#
# Manages starting, mounting, unmounting, stopping and monitoring of RAID devices
# which are preconfigured in /etc/conf.d/HB-ManageRAID.
#
#
# Created 11. Sep 2006
# Updated 18. Sep 2006
#
# rev. 1.00.2
#
# Changelog
#
# 18/Sep/06 1.00.1 more cleanup
# 12/Sep/06 1.00.1 add more functionality
# add sanity check for config parameters
# general cleanup all over the place
# 11/Sep/06 1.00.0 it's alive... muahaha... ALIVE... :-)
#
#
# TODO
#
# - check if at least one disk out of PREFIX_LOCALDISKS is still active
# in RAID otherwise consider RAID broken and stop it.
#
# The reason behind this: consider a RAID-1 which contains iSCSI devices
# shared over Ethernet which get dynamically added/removed to/from the RAID.
# Once all local disks have failed and only those iSCSI disks remain, the RAID
# should really stop to prevent bad performance and possible data loss.
