Thank you Tomas and Mario. I was able to recreate the mirror by reattaching. It seems that once a vdev has been added to a pool it is no longer possible to remove it. Is that right? For example if I created a pool that consisted of 3 single drives there would not be a way to remove a drive and reduce the number of devices in a pool from 3 to 2. Even if there is enough space in those 2 remaining drives to hold all the data. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
