FreeBSD 5.x also has the original vinum implementation plus gvinum so it should be possible to use that instead of needing to dump/restore. Though I think that there are a couple of limitations like no swap on the original vinum do to the addition of GEOM. > 2) There is at least one feature that vinum has that I don't see in > any GEOM class, that I'm using.

I think that either geom_ccd or geom_concat will allow you to concat more drives in and then use growfs to expand the fs. > > -- > Bill Moran > Potential Technologies > http://www.potentialtech.com -- I sense much NT in you. NT leads to Bluescreen. Bluescreen leads to downtime. Downtime leads to suffering. NT is the path to the darkside. Powerful Unix is.
