Answer: see explanation below.

Explanation

# vgdisplay

(Check the capacity of vg, if the capacity is not enough, need to create pv , vgextend , lvextend)

# lvdisplay (Check lv)

# lvextend -L +110M /dev/vg2/lv2

# resize2fs /dev/vg2/lv2

mount -a

(Verify)

——————————————————————————-

(Decrease lvm)

# umount /media

# fsck -f /dev/vg2/lv2

# resize2fs -f /dev/vg2/lv2 100M

# lvreduce -L 100M /dev/vg2/lv2

# mount -a

# lvdisplay (Verify)

OR

# e2fsck -f /dev/vg1/lvm02

# resize2fs -f /dev/vg1/lvm02

# mount /dev/vg1/lvm01 /mnt

# lvreduce -L 1G -n /dev/vg1/lvm02

# lvdisplay (Verify)
