What is in /etc/fstab?

Probably a line that looks a lot like this:

LABEL=/var              /var                    ext3    defaults 1 2

If that is the case, I'll bet /dev/hdb and /dev/hda have a
filesystem with "/var" as the label.  If that is what is in your
/etc/fstab, just go change it to be:

/dev/hdaX               /var                    ext3    defaults 1 2

    Thanks,
        Kirby
