#
# 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.
