Hello,

Today i create a new disk with ext3 and was going to mount it readonly
on my netbsd installation.

Here is a problem:

# mount_ext2fs /dev/wd0g /mnt  
mount_ext2fs: /dev/wd0g on /mnt: incorrect super block
# mount_ext2fs /dev/wd0g /mnt -o ro
usage: mount_ext2fs [-o options] special node
# mount_ext2fs -o ro /dev/wd0g /mnt 
mount_ext2fs: /dev/wd0g on /mnt: incorrect super block

dmesg says: 
Ext2 fs: unsupported optional feature
Ext2 fs: unsupported optional feature

Partition was created in linux. 

# uname -a
