Convert ext2/3 to ext4

“Let’s say you’re a little bit behind the times. You’ve wanted
to do some upgrading of your Linux machines but you’ve just not
really had the time. Or let’s say you did do some upgrading of your
Linux system but you didn’t make any changes to your file system
and you’re still running a machine with either ext2 or ext3. Now
that’s not necessarily a bad thing as both file systems work and
work well. But let’s say you do want to take advantage of some of
the features of ext4.

“In this article I am going to show you how to migrate your ext2
or ext3 partition to ext4. I will use a Ubuntu machine as an
example. I want to warn you that you could lose data by doing this
so, following good administrative practices, back up your data!
Once you are certain you have that backup of your data, it’s time
to begin.

“Kernel pre-requisite

“You must be certain you have a kernel that is at least
2.6.28-11-generic or higher. If not, do NOT continue on with this.
To find out what kernel you are running issue the command uname -r.
If your kernel is lower thatn 2.6.28-11 stop where you are and
close your browser.”
