Hi Matt, ZFS-team,
Problem
---
libzpool.so, when calling pwrite(2), splits the write into two. This is
done to simulate partial disk writes. This has the side effect that the
writes are not block aligned. Hence when the underlying device is a raw
device, the write fails.
Note: ztest always

Are you using compression=on? There was a bug in the past (fixed
now) where if compression was turned on, it was being computed by a
single thread. The ZFS team fixed the user data part of it (i.e
user data is compressed in parallel now), but the meta data part
is still compressed by one

machines).
On one host (a new install, I wiped out the snv62 install) the hint
