It's not a problem with ext3 support, it's something with knoppix. When I created a new ext3 partition, parted could resize it but as soon as I put knoppix on it, it couldn't. The version of parted shipped with knoppix is a compact version, maybe the full version would work better but then how could you install it to the CD? You couldn't use klik, klik needs a persistent home which needs the HD & parted only works on an unmounted HD. Easiest I think would be for you to remove packages you don't need. Start with 'localepurge' and then 'apt-get remove kde-i18n*' which will free up about 100 Meg of extra language support.

To resize ext3 partition with qtparted or parted on (unmounted) hda5 (for example) do this:

tune2fs -O ^dir_index /dev/hda5

tune2fs -O ^has_journal /dev/hda5

resize with qtparted or parted, then

tune2fs -O has_journal /dev/hda5

tune2fs -O dir_index /dev/hda5

Summary: Change ext3 to ext2, resize, then change ext2 back to ext3.

I did that all and parted says: "Error: Filesystem has incompatible feature enabled.

But now I can change the Size with qtparted, but it quits when doing it with an error.

dump2fs:

Code:

Filesystem features:      ext_attr resize_inode filetype sparse_super large_file

Some of these features seems to cause this problem... but which? And can I disable it without problems?

What I did was make a backup of the partition with partimage then delete and creat the new bigger partition.

After reloading it with the partimage backup I ran ext2resizer and that expanded it to fill the whole partition.

I already tried that, but PartImage quitted with error.. :/
I think the only way is to find out which feature doesn't work with parted and how I can disable it and enable it after the resizing again...
