Subjecte2fsck, LVM and 4096-char block problems

Using Linus' 2.4.10, unpatched. (Perhaps I need to patch the LVM stuff ;-)

I wanted to extend /usr/src from 19G to 20G.

I umounted /usr/src, lvextend -L +1G /dev/vg01/src, fsck -f /usr/src,
resize2fs /dev/vg01/src

resize2fs tells me to run fsck. Hmmmm... I just did.

I poke around a bit more and notice the following:

Oct 19 11:45:41 thune kernel: ll_rw_block: device 3a:00: only 4096-char
blocks implemented (1024)

Of course, dumpe2fs says:
Block size: 4096

I tried -f on the resize, and got LOTS of the 4096-char messages.

Some perhaps pertinent information.

Obviously I have the option of creating a new volume and moving things over
to that, but that sort of defeats the purpose of these particular tools.

Recommended course of action?
