Hi sirs

How can i do swap for work?
my swap status is

total used free shared buffers cached
Mem: 1000 983 16 0 49 711
-/+ buffers/cache: 222 777
Swap: 2047 0 2047

why this is not used ?

how can i do for work that ?

swap only gets used when you run out of RAM; as long as you don't, it remains at 0.

Thanks

Please

If you install several Linux versions, is it possible to use the same swap partition?
Now I am running open SUSE 10.2. I hope to install Fedora7 and Ubuntu.

My current hard drive has no space. I will buy a new hard drive to install Ubuntu and Fedora.
I think I need another swap partition on the new hard drive. Because Ubuntu and Fedora7 will be on the new drive.

My swap partition is hda7. I believe I have to create another swap partition on the new drive.
Your comments are welcome.

I made a mistake to double post.

You can use the same swap so long as you don't use it for persistent data across restarts.
Generally this means do not use suspend/resume on any of the systems.

Edit: yes,the swap can be on a different disk to the rest of the system partitions.

Thanks syg00 for the comments.

What about Solaris? If I install Solaris, will it recognize the swap partition?

I doubt it.
Last I looked at it Solaris used slices - I didn't try, but I doubt Linux will look at them.
If jlliagre doesn't pass by here, ask on the Solaris forum.
