Changing to ext3

Changing to ext3

[John J. Boyer]

Rafael,
Thanks for very good answers to my questions on backups and telnet. Now 
how do I change to ext3?
I tried to get the latest kernel for Redhat Linus, but the up2date program 
skips anything to do with the kernel, and if I download rpm's and try to 
do it manually I get tangled up in dependencies.
Thanks.
John

Here is a segment from ext3 FAQ
http://people.spoiled.org/jha/ext3-faq.html

Q: How do I convert my ext2 partition to ext3? (was: How do I use ext3?)
Before you can mount a partition as ext3 you have to create a journal on
it. The easiest way to do it is to type:

tune2fs -j /dev/hdaX

This can be done on an unmounted or on a mounted filesystem. If you
create the journal on a mounted filesystem you will see a .journal file.
Don't try to delete this and don't back this up or restore it from
backup! If you run tune2fs -j on an unmounted partition an unvisible
journal file will be created.
Now you can mount the filesystem as ext3 using:

mount -t ext3 /dev/hdaX /mnt/somewhere

With mke2fs -j /dev/hdaX you can format a partition as ext3 (as always
it will be also usable as ext2 partion).

--- end of segment.

Note that your kernel needs to have ext3 features compiled in, or your
system will become inoperable.

RPMs are a growing problem lately, that's why I started to move servers
under my control to Debian which has much better packaging system. You
might find apt tools for RPMs useful: http://apt.freshrpms.net

To convert form ext2 to ext3 do the following command as root:
tune2fs -j /
This will convert the root filesystem to ext3. All ext3 is really is just
ext2 with a journal on it. So that's all the the tune2fs program will do is
just add the journal to yoru filesystem. I suspect that the root filesystem
needs to be unmounted for thsi to happen so you probably need to do it from
a rescue disk or single user mode. I've not actually done it myself because
I just selected ext3 during the install of my linux when I last installed it
so there was no problem there. You will of course need to make sure that you
have ext3 support built into the kernel or you won't be able to use the
journal.

You need to specify the -f parameter to overide the default skip list.
Something like:

	up2date -u -f kernel

should do the trick.  See 'man up2date' for more details.
