Another one is that in one pool all vdev should be equal, i.e. not mixed like 2x7 and 1x6 (this configuration you most likely will need to force anyway). First, I'd assess what you want/expect from this file system in then end. Maximum performance, maximum reliability or maximum size - as always pick two ;) Cheers Carsten _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
