Thanks for the info Dave. I managed to find the cache file. 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.
