Here's my $0.04: Suppose you had 4 disks, configured as 2 mirrors. And you want to expand by adding another mirror. No problem. Suppose you had 4 disks, configured as raidz2. And you want to expand by adding a mirror. No problem. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
