jyap808 / resize_ext4_lvm_boot_cd.md
Last active January 4, 2016 20:49
Resize an ext4 LVM volume with a boot CD

Find the name of the Volume Group (henceforth “somevg”) that contains the root Logical Volume:

sudo lvs

(If it’s not showing up, try running sudo lvmdiskscan and sudo pvscan then try again.)

If you run ls /dev/mapper/ you may see that the Logical Volumes is not showing up. If it’s not there, you need to run the following command to make the kernel aware of the logical volumes:

sudo vgchange --available y <somevg>

jyap808 / resize_swap_lvm.md
Created January 28, 2014 21:33
Resize a swap LVM volume 
swapoff /dev/vg_foo/lv_swap
lvextend -L+100M /dev/vg_foo/lv_swap
mkswap /dev/vg_foo/lv_swap
swapon /dev/vg_foo/lv_swap

That is: disable swapping on the volume, extend it, re-create the swap area and enable swapping again.

Swap will need to be recreated with mkswap to the new size to be seen.
