Are you doing this send|recv within the same pool? What's the motivation for that? Can't you just use "zfs clone", which would be much faster and use less disk space? Or if you want another copy (which seems unlikely since you can already tolerate any 2 disks failing in your pool), then use "zfs set copies=2 <fs>". --matt _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
