OK, /backup was mounted read only, I did the following
umount /backup
mount -o rw /backup
[r...@arthur ~]# dd if=/dev/zero of=/backup/testfile bs=1024
dd: /backup/testfile: end of device

You can see by that snippet it barfed at 21627094 bytes (21 megabytes,
ish). /backup has 100s of GiB free.

I cannot get the system to generate a dump, even though dumpon verified
it's set to the swap drive but /var/crash stays empty. I have
dumpdev=AUTO in rc.conf and dumpdir=/var/crash as well.
Could this have anything to do with how I added the drive? I followed
the handbook instructions but maybe I messed it up.
