Description

the xymon-smart.sh and xymon-hddtmp.sh scripts have the following like the query disks:

ls /dev/disk/by-id/* | grep ve '-part' -ve '/wwn' |

the line should be the following to remove the mdadm raid devices:

ls /dev/disk/by-id/* | grep ve '-part' -ve '/wwn' ve '/md' |

In addition an the disks being used in mdadm raid are not going to to be listed in the subsequent mount query thus
an addition check should be added to agaist the /proc/mdstat for the mounted raid disk

#check if device is directly mounted
    if ! mount | grep -q /dev/$DISKDEV
    then
       # check if device is mounted by mdadm
        if ! cat /proc/mdstat | grep -q $DISKDEV
        then
            continue
        fi
    fi

  1. NOTE: Must be run as root, so you probably need to setup sudo for this.

ls /dev/disk/by-id/* | grep ve '-part' -ve '/md' ve '/wwm ' |
while read DISK
do
DISKDEV=`ls -l $DISK | awk -F/ '{print $NF}'`
DISKNAME=`echo $DISK | awk -F/ '{print $5}' | tr ":" "_"`

#check if device is optical
    if [[ $DISKDEV == "sr"* ]]
    then
        continue
    fi
#check if device is mounted
    if ! mount | grep -q /dev/$DISKDEV
    then
    # check if device is used by mdadm
        if ! cat /proc/mdstat | grep -q $DISKDEV
        then
            continue
        fi
    fi
#check if SMART is disabled and enable
    DRES=`sudo /usr/bin/smartctl -A $DISK`
    if [[ $DRES == "SMART Disabled. Use option -s with argument 'on'" ]]
    then
        sudo /usr/bin/smartctl -s on $DISK
        DRES=`sudo /usr/bin/smartctl -A $DISK`
    fi
hddtemp=`echo "$DRES" | grep Temperature_Celsius | awk '{print $10}'`
TEMP=": $hddtemp" 
    if [[ $hddtemp == "" ]]
    then
        TEMP="- No Temp Sensor Found" 
        COLOR="4&clear" 
    elif test $hddtemp -gt 55
    then
        COLOR="1&red" 
    elif test $hddtemp -ge 50
    then
        COLOR="2&yellow" 
    else
        COLOR="3&green" 
    fi
echo "${COLOR} $DISKNAME $TEMP"

done > /tmp/hddcheck

COLOR=`cat /tmp/hddcheck | awk '{print $1}' | sort | uniq | head 1 | cut -c3`
