I've done this on my testbed without any repercussions however I don't really care if I lose data on my testbed. I'm about to attempt this on my laptop which does contain data I do want to keep. Given that the ZFS code in -STABLE and -CURRENT are to a degree different, would there be any risk? If so can I manage that risk in any way? -- Cheers, Cy Schubert FreeBSD UNIX: Web: http://www.FreeBSD.org e**(i*pi)+1=0
