Error while doing a Vacuum

Hello,

I have a problem when I ran a VACUUM on a Postgresql database, I had tried
to do it a few times and the vacuum always stop in the same place with the
same error (or message), and it takes more than one hour before I got it.
The message that I get is in spanish and it says : No space left on the
device.

PostgreSQL version: 7.1.2
System: RedHat Linux 7.0
Computer PIII 800 Mhz 256 Mg RAM
