Swap file not being used...why?
 
I've partitioned my HDD and set aside 10 GB as Linux and 0.5 GB as Linux Swap, using the ext3 file system. I use slackware 9.1 ...my problem is that the swap space doesn't seem to be used at all...when i run a disk usage command it says 0% of the linux swap space is being utilised...I have 768MB of DDR ram on an Athlon XP 1900...im very sure that ive selected the right choices during installationa nd have also turned swapon

and another question..ive seen a program on the corner of teh screen in a couple of screenshots of fluxbox and blackbox...it displays all kinds of info lik CPU usage and HDD space...does anyone know what it is? can i download it for KDE?

All help is appreciated!!!

You should be happy your swap isn't being used, that means your RAM is doing an excellent job. Its not at all common that your swap will ever get used, its just that fallback type of thing to have just in case, etc.

Are you saying that you created a partition
of type 83, formatted using ext3 for swapping?

Please post
/etc/fstab
and the output of
mount


Cheers,

That's probably normal, but swap should be formated as swap, not ext3.

I seldom touch my swap with 512 MB ram, but use it frequently (especially while compiling) on a box with 384 MB.

The program you want is called GKrellm.

thanks for the quick reply everyone, tahnks naijin for Gkrellm..sorry that was a typo...my swap space is not ext3 its linux swap...yeah i guess ure right that i should be happy that my swap space is not being used, and my ram is doing a good job...

anyway

mount:
/dev/hda2 on / type ext3 (rw)
/dev/hda1 on /win-c type vfat (rw)
/dev/hdb1 on /win-d type vfat (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
proc on /proc type proc (rw)
usbfs on /proc/bus/usb type usbfs (rw)


my /etc/fstab

/dev/hda3 swap swap defaults 0 0
/dev/hda2 / ext3 defaults 1 1
/dev/hda1 /win-c vfat defaults 1 0
/dev/hdb1 /win-d vfat defaults 1 0
/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
/dev/sr1 /mnt/rw iso9660 noauto,owner,ro 0 0


thanks again everyone!

Zero or minimal swap usage is actually a good thing. Swap only comes into play if you exhaust your physical memory, which is undesirable. Assuming that you've got >= 256Mg RAM, you probably would use swap only lightly. Personally, I suggest making the swap partition no larger than 256 Mg. -- J.W.
