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
