# softraid.monitor
# Linux Software RAID check with mon compatible output/return values
# Call without arguments.

#   softraid.monitor learn
#   [ cat /proc/mdstat > /path/to/dir/mdstat.reference ]
# no administrative permissions needed for this script.
# Return values: 3 /proc/mdstat missing, no Software RAID?
#                2 reference file missing
#                1 RAID not okay
#                0 alles okay
