Is that how it works? With RAID-Z one FS block is spread onto N-1 disks + one parity. So you have one FS block which is divided to smaller N-1 "device" blocks. It's clever "trick" with it's own pros and cons. -- Best regards, Robert mailto:[EMAIL PROTECTED] http://milek.blogspot.com _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
