Do you know how to resize the swap partition (tools that allow me to do that task)?

And in theory, why must I force the swap to be the same as physical RAM? (not only to solve this problem).

Thanks

Samue,
You getting too much swap you should only have 512 Mb

Franck, thanks again.

I have 512MB of RAM and a 4GB of swap.

¿Is that the problem?
¿How can I solve that exactly?

Sorry for my inexperence.

Regards (and happy new year to all, I forgot in previous e-mail)

Hi,
You should check what is the size of the swap partition.
Let's suppose ypu have a 1 Go of ram, your should have a swap partition of 1 Go.

You should check with your swap.

I have an Adaptec 2410SA raid controller with RAID 1 configured on it.
The system is an AMD ATHLON 1800 CPU. With FC4 updated distro.

The system is working fine, but TOOOOOOOOOOOOO SLOOOOOWWWWWWWWWW.

Taking a view into startup messages I can see:

sda: got wrong page
sda: assuming drive cache: write through

In dmesg:

...

I think changing write through into write back cache will solve the
problem.

The controller utility was used to configure all caches in the drivers.

Any help about this topic?

Thanks
