Yes, the algorithm is conservative and very often wrong until you get close to the end. In part this is because resilvering works in time order, not spatial distance. In ZFS, the oldest data is resilvered first. This is also why you will see a lot of "thinking" before you see a lot of I/O because ZFS is determining the order to resilver the data. Unfortunately, this makes time completion prediction somewhat difficult to get right. > Any thoughts on my other issue? > Try the zones-discuss forum -- richard _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
