Ext3 Partition Resize


Does anyone know if it's possible to resize an Ext3 partition on a disk that is full. For example:

10GB disk:

    /: -using 2.0GB
 /usr: -using 6.0GB
/home: -using 1.5GB
/swap: -using 0.5GB
-----------------------
             10.0GB

can I make my root partition smaller and increase /usr so that I can install more programs?

Yep... get one of the many rescue-cd's or Knoppix > 3.2
and use parted ...

Cheers,

As far as I know, you can only resize the end of an ext3 or reiser partition non destructively.

You cant change where the partition starts.

So in your case, I believe you can make the "/" partition smaller, but you couldn't increase the /usr partition to fill the space w/o losing all the data in it.


For a Rescue CD for partitioning, I suggest "System Rescue CD" (origional name, huh) . Its only about 40MB and it comes w/ all the partitioning tools out there, even a bunch of GUIs for them. That, and it comes with other basic recovery tools as well.

Code:
from `man parted`

       parted  is a disk partitioning and partition resizing pro-
       gram.  It allows you to create, destroy, resize, move  and
       copy  ext2,  ext3,  linux-swap,  FAT and FAT32 partitions.
       This is useful for creating space for new  operating  sys-
       tems,  reorganising  disk  usage,  and copying data to new
       hard disks.
Cheers,
Tink

Contrasutra is right, and I know this for a fact because I just used parted (to try resize my ext3 partition) less than a month ago.

However, I do recall there's a command somewhere to convert an ext3 partition to ext2, and vice-versa. I've read it somewhere, but dammit, I can't recall where! I'll update when I can remember.

strange. . .

All went well getting parted to run. . but I get a strange error message when I try to resize the root partition.

"incompatable feature enabled on this filesystem"

Do you think that has anything to do with the fact that EXT3 is a journalized filesystem? I'm just reaching for answers . . what do you guys think?


. . . Ah nevermind. . . I see the above post. . I will try to find a man page. Thanks for all your help guys.

Well that's what they claim anyway. I used a friend's copy to see if it would work. It didn't, that's why I finally started a new thread and posted here. I thought it might be something specific to my situation, but I guess I was wrong.

the version I used was 8.0 running on windows xp, and I used it to resize, move, and convert a primary ext3 partition to a logical partition.
