You have two ways to increase the size of this pool (sanely). First, you can add a third mirror vdev. I think that's what you're specifically asking about. You do this with the "zpool add ..." command, see man page. Second, you can add (zpool attach) two larger disks to one of the existing mirror vdevs, wait until the resilvers have finished, and then detach the two original (smaller) disks. At that point (with recent versions; with older versions you have to set a property) the vdev will expand to use the full capacity of the new larger disks, and that space will become available in the pool. -- David Dyer-Bennet, d...@dd-b.net; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
