returning ext3 to ext2

returning ext3 to ext2

[Shaun Oliver]

hi,
the subject says it all.
is there a way one can return an ext3 filesystem to ext2 short of
reformatting it?
any help would be greatly appreciated.

Hi
Well, I'm not sure why you would want to, but the simplest way is:
mount the ext3 filesystem as ext2
then remove the .journal file from the root dir of the filesystem
That clears away ext3. If you want to use it as ext2 but don't necessarily want to remove the ext3 capability, just mount it as ext2. Again, not sure why anyone 
would want to do this, given ext2's extremely long boot-up check after an improper shutdown.

there's a reason for this.
for playing audio and various other tasks, ext2 is a good deal faster.
so where's the journal file then lol.

General linux question

[Sina Bahram]

Ok, I installed Fedora today, and I have one of the most basic and
simplistic questions probably ever conceived of; however, I didn't see a
single screen that asked me if I want to use KDE or Gnome for my desktop
environment. I did do a full installation so I'm not worried about not
having it, but how do I check if I am running gnome or kde for the
desktop environment. Is there any command I can do via telnet? Also how
can I enable telnet and ftp. I can ssh into the box but it's a crappy
ssh and I want to enable the telnet client and the ftp server. Don't
worry about security at all. This thing is behind an extremely good
hardware firewall and right now I'm not beginning to be concerned with
security issues. How do I just get an ftp that will let me do anything I
want.

Thanks,
Sina

The configuration of Xwindows use is at /etc/X11. However, I don't think
you need to worry about it. It's not as if you can't smoothly stray from
one to another.

Rather, your concern is to have the desktop come up talking with
Gnopernicus following your login on the graphical login dialog--or
following your launch of gnopernicus from the command line.

Areyou unable to use your Fedora Core system natively for some reason?
The results and the learning curve will be significantly enhanced if you
do. Certainly, you're not going to succeed with Gnopernicus over telnet,
at the very least.

However, to answer the question you asked, you'll need to enable both
telnet and vsftp servers, and allow their ports if the Linux machine's
firewall is on, as it likely is.

Here's what to study:

Learn about the service command:

service [service.name] start/stop/restart

For the more permanent fix, learn the chkconfig command.

To enable/disable various firewall (and other) settings, use the setup
command.

Look at the configurations for vsftp under /etc and tweak as you see
fit. Also, edit the telnet configuration file under /etc/xinetd.d/ --
and be aware that you need to restart xinetd after so doing.

				How do I just get an ftp that will let me do anything I
> want.

Well, I have never heard of an interface that lets one do anything they
want. However, you can configure vsftp to do all that it can for you as
described above.

I seem to recall that there should be a .journal (note the period in
front) file in the file system's root directory. However, I've just
looked through 3 different ext3 file systems, and can't find it
anywhere. Maybe something has changed between the early and current
versions of ext3.

I believe you are thinking of reiserfs which has the .journal file.

Re: returning ext3 to ext2

[Cheryl Homiak]

No, ext3 did also have the .journal file, unless something has changed
since I did it.
I know, because I deleted at least one when trying to go back to ext2. You
should have a .journal on any partition where you ran tune2fs to get the
ext3 system, unless you chose to put the journal on an external device,
and I imagine you'd know if you had chosen to do this.
Also, if you are changing to ext3 or changing back, don't forget that you
have to also change /etc/fstab accordingly.

Re: returning ext3 to ext2

[Steve Holmes]

Yes, there is a .journal file in the / directory.  Interesting thing
though; I did a 'ls -la' to show dot files and the .journal on my box
shows a last mod date of 3 Mar 2003 and I've been using my machine all
along here so not sure what that really means.  I figured it would
have a recent time stamp.

Well, I now see that on one of my other linux machines here that a
.journal file does *NOT* exist and when I do the mount command, it
does indeed show that it is an ext3 file system so my previous
paragraph must be moot now.  <hmmm> wonder what will happen if I
delete the .journal on this machine? It's 33 megs I can get back:)

Re: returning ext3 to ext2

[Adam Myrow]

I just looked at the manpage for tune2fs, and I think the proper way to
convert EXT3 back to EXT2 is like so.  Type tune2fs -O ^has_journal
/dev/hda2.  Substitute the right partition for /dev/hda2.  I just tried
this and there was a long burst of disk activity on the partition, so I
assume it deletes the journal when clearing this feature.  So, this seems
to be the way to do it.  I'd also edit /etc/fstab to show the filesystem
type as ext2, and you may want to unmount the filesystem if possible
before running tune2fs as a safety precaution.  You can find out a lot
about a filesystem with dumpe2fs /dev/hda2.  Again, put in the appropriate
partition.  You should also pipe the output through a pager like less, as
it's quite long.  You can find out pretty much all the settings of a
filesystem from this command.

Janina,

I got two copies of your email. One of them looked like it was sent to
me personally, since there were no advertisements or anything on the
bottom of the email. The other email looked like it was in response to
an email I sent to speak up; however, I am almost possitive that I sent
that "general linux question" email to blindy2?
Any thoughts on this?

Thanks,
Sina

Hi,

     Actually, there's no need to edit the xinetd files.  chkconfig 
handles this also.  Just do: chkconfig telnet on
It's most spiffy.  chkconfig will signal xinetd for you, so you don't even 
need to restart it.
          HTH.
