I thought I'd do some ext4 experiments.

I formated a ext4 loopback filesystem, but mount is failing:

# mount -t ext4 -o loop /home/ext4test.loop /mnt
mount: unknown filesystem type 'ext4'

Where can I get a version of mount that recognizes ext4?

try "-t ext4dev"

If that still doesn't work (it should) then do "modprobe ext4dev" and try
again

In 11.1, ext4 is still in its experimental stage. ext4 without the dev will
come in 11.2

Anders,

I may be out of luck. This machine is running 11.1, but to experiment
with the latest ext4 stuff I downloaded a 2.6.31-rc7 kernel from
kernel.org and compiled it and booted into it.

It is running fine from my minimal testing. I also downloaded
e2fsprogs from the main devel's git repository and compiled /
installed it.

That gives me mkfs.ext4, but mount is still not working after trying
both of your suggestions.

I've got a laptop I'm not using much. Sounds like it is time to
install factory m6 on it if I want to continue this effort.

Thanks
Greg
