Hi Fancypiper. I did as you have suggested. Please ignore the
sda part since I do not use SCSI device.

Have you formatted the partition /dev/hda8?

mkreiserfs /dev/hda8

Hi fancypiper.

I did this. vi /etc/fstab
/dev/hda6 / reiserfs defaults 1 1
/dev/hda7 /tmp ext2 defaults 1 2
/dev/hda10 /usr reiserfs defaults 1 2
/dev/hda9 /opt reiserfs defaults 1 2
/dev/hda8 /var reiserfs defaults 1 2
/dev/hda1 /boot ext2 defaults 1 2
/dev/hda11 /home reiserfs defaults 1 2
/dev/sda6 /mnt ext2 defaults 0 0

#/dev/fd0 /floppy auto noauto,user 0 0

proc /proc proc defaults 0 0
# End of YaST-generated fstab lines
=======================

/dev/hda8 is already format as reiserfs.
/dev/hda is a boot up hard drive and it works fine.

Then that partition should be mounted automatically upon boot. It is probably marked so that you can't screw around with it because the system uses it to store stuff for it's use.

cd /var
ls

See anything?
