R: Converting ext2 filesystem image to ext3

[Andrea Paterniani]

I have verified the status of /dev/loop0 then I did the following:

losetup /dev/loop0 root_fs_arm_nofpu.ext2
tune2fs -j /dev/loop0

I got the following error:

	tune2fs: Cannot allocate block in ext2 filesystem

The message arises when tune2fs attempt to create the journal inode.

Any idea?

-Andrea

That should work with an image as well; if tunefs refuses to use the
image, then first manually attach it to to a loop device (using the
`losetup' tool.)
