Can't mount xfs with log version=2

[Juergen Rose <rose@xxxxxxxxxxxxxxxxx>]

Hi,

I have here a software raid device /dev/md/0. If I create the filesystem
with:
        mkfs -t xfs -f /dev/md/0
I can mount the device, but I get a lot of "raid5: switching cache
buffer size" warnings. If I create the filesystem with
        mkfs -t xrs -f -l version=2 /dev/md/0
I can't mount the device: I get:

mount: wrong fs type, bad option, bad superblock on /dev/md/0,
       or too many mounted file systems

I habe linux-2.4.21-ac2, which was configured with:
        CONFIG_XFS_FS=y
        # CONFIG_XFS_RT is not set
        # CONFIG_XFS_QUOTA is not set

I would appreciate any hint very much. Please answer also to my email I
don't follow this list.

        Regards Juergen
