On my install its under /boot/zfs/zpool.cache. I have also seen reports of it under /etc/zfs whilst googling (I think that was Solaris though). For safety's sake I backed it up and rebooted the server. Zpool then lost all trace of the old array. Then I used the zpool import command which was able to automatically locate the array then I simply imported it by its name. Magically all is working agian! So I can now get my photos off the old array and on to the new one. Thanks again for the info, its been really useful. Charlie
