Nope. Neither the physical nor logical disk can be greater than 1TB. Using Vinum or ccd is not a work-around for this problem. Now, *if* you had a hardware RAID system that could present it's storage to the host as multiple LUNs that were each < 1TB (each one showing up as seperate physical disk devices), then you could use it with FreeBSD, but that's not what has been discussed here. -DG David Greenman Co-founder, The FreeBSD Project - http://www.freebsd.org President, TeraSolutions, Inc. - http://www.terasolutions.com President, Download Technologies, Inc. - http://www.downloadtech.com Pave the road of life with opportunities.
