Have you ever wanted to change the amount of swap space on your VM ? Here's how to !
disable existing swap
get some more disk space
Either repartition an existing disk or add a new disk to your GNU/Linux machine or VM
and use fdisk to create/repartition a swap partition (type 82) for your swap space
# fdisk /dev/mydisk
verify
# fdisk -l /dev/mydisk
Disk /dev/mydisk: 2147 MB, 2147483648 bytes
255 heads, 63 sectors/track, 261 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/mypart1 1 261 2096451 82 Linux swap / Solaris
make a swap partition and use a speciail swap disk label !
# mkswap -L myswap /dev/mypart1
add to fstab
Add swap partition to fstab using your special swap disk label !
LABEL=myswap swap swap defaults 0 0
reenable swap
reboot (optional)
# reboot
and login and check new swap space is available
