I made a script for myself, that collects the information by
inspecting /sys instead of doing mdadm -E. The script see all mdraid
devices and all devices that belong to a mdraid. I would like to know
if the script works or not. It works for me.
#!/bin/bash
# $1 - procfile
# $2 - File to log
function cat-file () {
echo $1 >> $2
if [ -e $1 ] ; then
${CAT} $1 >> $2
else
echo "$1 don't exist" >> $2
fi
echo >> $2
}
FILEMD=md-list
echo "Get slot positions of the devices in mdraid" >> ${FILEMD}
for file in /sys/block/md* ; do
echo $file >> ${FILEMD}
for dev in $file/md/rd* ; do
echo $dev >> ${FILEMD}
ls -alF $dev >> ${FILEMD}
done
echo >> ${FILEMD}
done
echo "Get more info about devices in mdraid" >> ${FILEMD}
# get info about all devices that are in a mdraid.
# similar to mdadm --examine ?
for file in /sys/block/md* ; do
echo $file >> ${FILEMD}
for dev in $file/md/rd* ; do
echo $dev >> ${FILEMD}
ls -alF $dev >> ${FILEMD}
for fi in $dev/* ; do
if test `basename $fi` = "block"; then
ls -alF $fi >> ${FILEMD}
else
cat-file $fi ${FILEMD}
fi
done
echo >> ${FILEMD}
done
echo >> ${FILEMD}
done
