# commands to resize volumes, for example useful to utilize more storage after resizing an attached EBS manually 

# Expand the PV on /dev/sda1 after enlarging the partition with fdisk:
pvresize /dev/sda1
# Extends the size of the logical volume "vg01/lvol10" by 1GiB 
# on physical volume /dev/sda1. This is only possible if /dev/sda1 is a member of volume group vg01 and there are enough free physical extents in it:
lvextend -L +1024 /dev/vg01/lvol10 /dev/sda1
