resilver & scrub time aren't primarily influenced by the number of bytes to resilver or scrub. It's primarily influenced by the number of fragments in said data... If you have no snapshots, and you never did, and if your files were initially written serially and quickly... Then your scrub & resilver time should be very quick, because all your data is laid out on disk serially and therefore you're able to cover a large number of GB/min. But if you have been performing random reads/writes over a long period of time... creating and destroying snapshots... etc ... Then it could be pretty awful. All of this is, of course, no concern for SSD drives with really high IOPS. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
