Thanks for the reply, I'd rather keep the pool to 3 disks if possible, so I can keep the option of adding 3 more disks, whether it be for backup or recovery purposes later. If i were to add, for example a 3x2TB raidz1 alongside the 3x750GB, what is the best way to transfer things from one pool to the other? Minimising time expended and of course taking full advantage of the new capacities. thanks - -- Matt Harrison [EMAIL PROTECTED] http://mattharrison.org -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (MingW32) iEYEARECAAYFAkhmDwUACgkQxNZfa+YAUWEzJACaAqkgsL6lPXXIwup2glcFv33B rVYAn3wznTY4K0+oyiKs22s+I+n0J9ov =ejuw -----END PGP SIGNATURE----- _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
