• Execute the following command
  • cat /etc/fstab > /var/tmp/fstab
  • df > /var/tmp/df
• take a print out of /var/tmp/fstab and /var/tmp/df or note down the contents.
• The file /var/tmp/df will contain entries similar to
  • Filesystem 1K-blocks Used Available Use% Mounted on
    /dev/hda2 8262068 1021092 6821280 14% /
    tmpfs 514336 12 514324 1% /dev/shm

    /dev/hda3 373633988 346569304 8085092 98% /var
• The file /var/tmp/fstab will contain entries similar to
  • /dev/hda2 / ext3 acl,user_xattr 1 1
    /dev/hda1 /boot ext3 acl,user_xattr 1 2
    /dev/hdb1 /home ext3 acl,user_xattr 1 2

• You can also note down the devices by looking at the output of the command "fdisk -l"
• Note down all the devices i.e. note down entries of the type /dev/hda1,
  /dev/hda2 and so on for both the outputs. Please note that all devices are
  not shown in the output of "df" and hence we executed the command "cat /etc/fstab".
• Reboot the system
• Change the boot up options to boot from cd
• Insert the Suse 9.1 cd no. 1.
• During the boot up options will appear on the screen which will be Installation, Boot from hard disk and so on. From that choose "Rescue System"
• Run e2fsck for each of the devices which were noted down by using the following command
  • e2fsck -f -y /dev/hda1
  • e2fsck -f -y /dev/hda2
• Run e2fsck as shown above for each and every device that you have noted down.
• e2fsck will repair the filesystems if it finds any errors in it.
• Reboot the system without the cd.
