You might have just run out of entropy on the PRNG. That and small
writes will kill you. Try:
dd if=/dev/urandom of=/dev/sdX bs=2M
next time. It should finish in several hours. A 20TB ZFS array will be
done in less than a day (the compression ratio is wonderful with
/dev/zero...). That and a scrub will let you know which disks got
dropping in shipping.
