swap space: add after install?

wetnose23 · 05-19-2006, 11:36 PM

hi.. is there a way for me to add swap space without damaging anything?

i created the partition during setup (960MB) but looks like i forgot to tell Slacky where it is located.

thankx

Just add to /etc/fstab:

Code:

/dev/hda4        swap             swap        defaults         0   0

Change /dev/hda4 to whatever your swap partition is.
If needed, run

Code:

fdisk -l

to let you know what partition it is.

Then, either reboot, or type

Code:

mount -a

as root to mount it.

To double check it is mounted, just type

Code:

mount

It will print a list of mounted devices

/dev/hda1 swap swap defaults 0 0

mount -a

Read

Code:

man mkswap

And

Code:

man swapon

in creating this file from "man mkswap"
dd if=/dev/zero of=swapfile bs=1024 count=65536

the "count" would that be the blocks...
Device Boot Start End Blocks Id System
/dev/hda1 1 117 939771 82 Linux swap

...939771?

thankx

"dd if=/dev/hda1 of=swapfile bs=1024 count=939771"

is what i have written.. not implemented
