OKay so the zpools appear to be back in spite of the strange situation <br>
with the cachefile property is empty everywhere. My guess is the zpool<br>
rc script is bring in information during early boot.<br>
<br>
Why the zfs filesystems on proteus do not mount? Well that is a strange <br>
problem but at least the zpool can be used.<br>
