You're facing a heck of a lot more than one problem. Did you check the
log you included? You're getting a bunch of seek and CRC errors on the
drive. That's bad. Don't do anything else until you get that sorted
out. It may be that you forced a partition beyond the end of the drive.

Egads! No, that's not a good idea. I'd change things as follows (all
in single user or rescue mode):
chroot /mnt/sysimage (Only if you booted in rescue mode)
mount /dev/hda5 /mnt/hda5
(Mount the new partition)
cp -a /var/* /mnt/hda5 (Copy the /var/files to it)
umount /mnt/hda5 (Unmount the hda5 partition)
mv /var /var.old (Rename your old /var directory)
mkdir /var (Create a new /var directory)
mount /dev/hda5 /var (Mount /dev/hda5 as /var)
rm -rf /tmp (Delete your current /tmp directory)
ln -s /var/tmp /tmp (Symlink /tmp to /var/tmp)
exit (Only if you booted in rescue mode)
exit (Reboot)
This mounts the partition where /var should be and allows its "tmp"
directory to do double duty (as both /var/tmp and /tmp).
Don't do ANYTHING until you sort out the seek and CRC errors. Something
looks very bad there.
