So here are the various configs (raid0.conf from raidctl -G raid0); I omit
sd1's info (normally identical/analogous to that of sd0) because I just 
pulled the disk to simulate a RAID failure. I'm unsure about whether the dump 
attempt was with a healthy or (artificially) failed RAID, I think it was 
with a healthy one.
