http://perforce.freebsd.org/chv.cgi?CH=54905 Change 54905 by jmallett@jmallett_oingo on 2004/06/14 06:12:51 Give a half-assed go at an ofwdisk alike arcs_disk. Right now it will only report the disk as being 8 blocks big. I'm hopefuly I can use this to read the volume header and figure out the size of the disk that way and reattach. I don't know if that's acceptable in the GEOM world. I think I can do it all in probe, though. Also need to do a lot to ARCS to give it some physical pages it can map into a space that's likely to work for ARCS, so that we don't have to worry about what address space buffers get passed to it. Right now this probably doesn't even come close to working, it's being committed as a placeholder.
