Provided that the external usb disk isn't already mounted, it ought to work, but performance may suck for various reasons. However, your zpool syntax is wrong. The correct invocation is "zpool import <poolname>". But since ZFS supports file-backed vdevs, you could skip a step and omit the mdconfig. Just do "zpool import -d /mnt/files/ronald <poolname>" instead. -Alan
