Thanks Edward. In that case what 'option' would you choose - smaller raid-z vdevs or larger raid-z2 vdevs.
I do like the idea of having a hot spare so 2x 7 disk raid-z2 may be the better option rather than 3x 5 disk raid-z with no hot spare. 2TB loss in the former could be acceptable I suppose for the sake of better protection. When 4-5TB drives come to market 2-3TB drives will drop in price so I could always upgrade them - can you do this with raid-z vdevs, in terms of autoexand? There might be the odd deletion here and there if a movie is truly turd, but as you say 99% of the time it will be written and left. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
