tune2fs change ext2 to ext3

i have trouble install ubuntu while i already have slackware inside my comp. it said the slack uses ext2 so it had an error. so i wonder to change the ext2 system to ext3 without re-installing the system.
here what i got from the internet. using tune2fs program that already inside the slack 12.

  • Log in as root
  • Make sure /etc/fstab has /dev/hda10 mounted to /test as ext2, read write
  • umount /dev/hda10
    • If you can’t unmount it, then remount it read only (mount -o remount,ro /dev/hda10)
  • tune2fs -j /dev/hda10
  • Edit /etc/fstab, and for /dev/hda10, change ext2 to ext3
  • mount /dev/hda10
  • /sbin/shutdown -h now
  • mount | grep /dev/hda10
    • If it’s not shown as ext3, reboot, if still not, troubleshoot
    • Otherwise, you’re done.

there i think my ext2 changed ext3. now let’s try the ubuntu.
