Hello!
So can anybody give me some advice on this? Should I really delete
the existing file system and create a new one with the 'sparse_super'
flag off?
Thanks.

Hello!
I'm new (well, actually, very very very new) to DragonFlyBSD and
currently doing my first steps with it. I have Ext2 and Ext3
partitions on my HDD (created under GNU/Linux) and I cannot use them
under DragonFlyBSD. The problem is that when I try to mount any of
them, I get the following error message:
# mount /dev/ad4s3 /mnt/data/
mount: /dev/ad4s3 on /mnt/data: incorrect super block
Or if I state the FS type explicitly, I get this:
# mount -t ext2fs /dev/ad4s3 /mnt/data/
WARNING: R/W mount of #ad/0x40002 denied due to unsupported
optional features
ext2fs: /dev/ad4s3: Invalid argument
The only mode I can mount these file systems in is read-only mode.
However, the file systems are not usable in this mode either, because
I can only list the root catalog of the corresponding FS. Any attempt
to list other catalogs or read some files leads to the following
error message on the screen:
and a system reboot.
I searched over Internet for a similar issue and found only one sane
article mentioning this problem
( http://onlamp.com/pub/a/bsd/2000/11/16/Big_Scary_Daemons.html ). Its
author tells that the root of the problem is the 'sparse_super' flag
set on the Ext2 file system and suggest to turn this flag off:
tune2fs -s off /dev/sda3
I tried it under my GNU/Linux system, but it says only:
Clearing filesystem feature 'sparse_super' not supported.
and does not do the job.
So now I just do not know what to do. How cat I use my existing
Ext2/Ext3 file systems on DragonFlyBSD? Any suggestions?
Thanks.

It may need e2fsprogs? Have you tried "e2fsprogs" from pkgsrc? "It
provides the filesystem utilities for use with the ext2 filesystem.
<http://e2fsprogs.sourceforge.net/ext2.html> It also supports the ext3
and ext4 filesystems."
