Well that error makes a lot more sense, but doesn't pinpoint the exact

I don't know what this is:  zfsinstall.sh

It's not part of the base system.  Without more info, my best guess is that
your zfs module is out of sync with your kernel.  Two things you can do,
install a clean FreeBSD, and just use zfs from there.  It works.

Or resync the kernel/modules by rebuilding them.

Make sure your src tree is in sync, eg csup with RELENG_8_1 or whatever
you're trying to run
Follow these instructions:

Just rebuild with GENERIC to make sure no other vars are interfering.  That
means don't use the KERNCONF=MYKERNEL part of the line or at least set it to

Once you have installed the new kernel, reboot and kldload zfs should work.
