Resizing a Red Hat swap space

The general procedure for resizing a swap space is as follows (assuming the swap space is set up as a logical volume within the root volume group called vg_root), for example to resize a swap space to 8 GB:

# swapoff -v /dev/mapper/vg_root-lv_swap
# lvm lvresize /dev/mapper/vg_root-lv_swap -L 8G 
# mkswap /dev/mapper/vg_root-lv_swap
# swapon -va
