Actually, a scrub without checksum places far less burden on the disks and their firmware than ZFS-style scrubbing does, because it merely has to scan the disk sectors sequentially rather than follow a tree path to each relatively small leaf block. Thus it also compromises runtime operation a lot less as well (though in both cases doing it infrequently in the background should usually reduce any impact to acceptable levels). - bill This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
