Do you have snapshots taking place (like in a cron job) during the resilver process? If so, you may be hitting a bug that the resilver will restart from the beginning whenever a new snapshot occurs. If you disable the snapshots during the resilver then it should complete to 100%. -Eric _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
