It looks like it's doing a somewhat misguided check which is appropriate for a device in the root pool which the BIOS needs to be able to boot from, but probably not for the cache device. Anyway, you could try simply creating standard FDISK/Solaris/vtoc partitioning on the SD card, with all the free space contained in one slice, and give that slice to ZFS. -- Andrew _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
