Not a particular easy testcase.

This is what I did:

On the crashing machine with the dm-encrypted xfs volume:
ionice -c 3 socat TCP4-LISTEN:5555 - >backup.tar

On the source machine:
tar cv dir |socat - TCP4:targetmachine:5555

You will certainly not need to use tar.

socat /dev/zero TCP4:targetmachine:5555 should work as well.

I don't know if TCP traffic is really needed probably it is.

Regards

Sven
