[SOLVED] how to set swap device

sumeet inani · 09-15-2009, 01:56 AM

is it possible to add option in kernel line of bootloader so that DSL uses a particular partition as swap.

In most Linux distributions you use the /etc/fstab to set swap files, which are loaded at boot.

an example of a swap line
/dev/sda6 swap swap defaults 0 0

you can also use the command 'swapon <swap partition>' to activate the swap partition.

I'm not sure about the kernel but I hope this helps.

Actually I am running damn small linux from its iso image so contents are dynamically stored on /ramdisk/ during boot.I have read a few cheat codes for kernel which allow you to set boot configuration.I was wondering is there a way that I can tell DSL to use my specified partition as swap otherwise it detects swap file system on my both hard disk & uses them.

i discourage using it directally from the iso

SOLUTION FOR ALL
Question)Is it possible to specify swap device in GRUB bootloader?
Answer)No

Question)I forgot to create swap device during installation.What should I do?
Answer)
Create swap file of size 1.5 to 2 times RAM as follows.
Run as ROOT
(1)dd if=/dev/zero of=/swapfile bs=1024 count=1048576
NOTE:1048576=1024x1024KB=1GB so calculate number of KB's for your RAM by remebering 1MB=1024KB,1GB=1024MB.
(2)mkswap /swapfile
(3)swapon /swapfile
(4)add following line to /etc/fstab
/swapfile swap swap defaults 0 0
