How to create a logical volume report of a volume group
From Wiki-UX.info
Abstract
This article presents a script that can be used to create a report of the configuration of the Logical volumes available on a LVM Volume Group. Two, versions are presented.
Abridged Report
if [ -f /tmp/lvol.out ]; then
rm /tmp/lvol.out
fi
for lv in $(vgdisplay -v /dev/<vgname> | awk '$0 ~ /LV Name/ {print $3}')
do
lvdisplay -v $lv | head -n 30
echo
done > /tmp/lvol.out
Example:
The following is an output example of the report on /dev/vg00 volume group.
# cat /tmp/lvol.out
