Hey guys, i realized today after class that during my install i NEVER formatted my Swap parition.

My teacher said that this means im running with out one now, even though i have the partition made.

Is there a way with out having to reinstall to format this swap to make it functional?

Thanks.

you created a swap partition but never formatted it?

try issuing this command:

free

you should see memory useage stats... if you don't see any mention of Swap: then you have no swap file running.

[root@fishbone root]# free
total used free shared buffers cached
Mem: 127440 120876 6564 0 54492 10912
-/+ buffers/cache: 55472 71968
Swap: 1052248 43084 1009164


If this is so, post back and we will tell you how format it.

oh, is the partition mentioned in /etc/fstab??

ie:

[root@fishbone root]# more /etc/fstab
LABEL=/ / ext3 defaults 1 1
none /dev/pts devpts gid=5,mode=620 0 0
LABEL=/html /html ext3 defaults 1 2
none /proc proc defaults 0 0
none /dev/shm tmpfs defaults 0 0
/dev/hda2 swap swap defaults 0 0
/dev/cdrom /mnt/cdrom iso9660 noauto,owner,kudzu,ro 0 0
/dev/fd0 /mnt/floppy auto noauto,owner,kudzu 0 0

total used free shared buffers cached
Mem: 515612 201592 314020 0 16652 100200
-/+ buffers/cache: 84740 430872
Swap: 0 0 0

it mentions it...but its all 0's

infy@inferno-linux:~$ more /etc/fstab
/dev/hdb1 / reiserfs defaults 1 1
/dev/cdrom /mnt/cdrom iso9660 noauto,owner,ro 0 0
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
proc /proc proc defaults 0 0

Here is the Red Hat Guide on How to Install a Swap partition properly, by creating it, etc:

http://www.redhat.com/docs/manuals/linux/RHL-9-Manual/custom-guide/s1-swap-adding.html

That tells you everything I think you will need to know.

...and yes, it looks like you have not got an initialised swap partition.

This probably doesn't matter too much if you have like 1 GB or so of RAM, but I would add one just anyway. Linux kernel is very good about not using swap file or partition unless it has to, unlike Windows which can be garbage in that regard.

infy@inferno-linux:~$ free
total used free shared buffers cached
Mem: 515612 168112 347500 0 14712 80716

Swap: 2097136 0 2097136


Ive got swap now.

Thanks again.

SCORE!
