Converting ext2 to ext3

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.
