My recent experience with os_111b, os_134 and oi_147 was that subsequent failure and disk replacement causes resilver to restart from beginning, including the new disks on the later pass. If disk is not replaced, the resilver would run to completion (and then a replace could be performed with a new resilver). This however is an issue that is being developed further so changes may be coming. -- - Tuomas _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
