[ale] who is eating my drive

[Lightner, Jeff]

swapoff is used to disable a swap device according to the man page.  I
haven't used swapoff myself.

 

After you've stopped the swap (or prevented it from coming up) you can
remove it as a swap device from the partitioning (e.g. using fdisk or
parted) and use the space for something else.   The simplest thing would
be to use it to create a new filesystem.   You can extend the root
partition but that takes some planning an effort because you have to
extend the filesystem and since it is root it gets a little more
involved.

 

I have never heard anything that says swap can't be on a primary disk
partition and am pretty sure I've done that in the past.   However,
these days I typically setup only two primary partitions - one for /boot
and one for LVM then I make my filesystems and swap in the LVM volume
group.   Partions have limitations that I don't care for as opposed to
LVM.

Hmm.  Makes sense.  But I dont think you can make swap on the primary
parition.  To make swap space you have to create extended and on that
extended you setup up swap.

Thats my understanding may be (and obivously ) it is wrong.

Not sure how to undo the swap space.

I have 8GB of Memory allocated to this VMWare session.

I may not need almost any swap at all.

Can I reclaim all the swap as a regular drive ?  If so how do I do that
?

It is showing you made /dev/sda2 your Extended partition of 8 GB then
used up all 8 GB in the sub-partition of the Extended partition as a
SWAP device (/dev/sda5).   (By the way you don't typically use Extended
partition until you run out of primaries - you could have made /dev/sda2
itself the swap device.

 

Type "swapon -s" and you should see this device.

Thanks for all your time.



Here is the output of the fdisk -l command

devusr at devusr-virtual-machine:~$ sudo fdisk -l /dev/sda

Disk /dev/sda: 22.5 GB, 22548578304 bytes
255 heads, 63 sectors/track, 2741 cylinders

So what should I be looking here for ?
