There is no /dev/gpt/label to even attempt to mount. Here is what I did: gpart add -t freebsd-swap -i4 vtbd0 gpart modify -i4 -lswapfs2 vtbd0 At this point, I can see the new swap partition. However, when I reboot, it's no longer there. So, I tried to follow the above commands with: gpart commit vtbd0 And I get "Operation not permitted" So, I did this: sysctl kern.geom.debugflags=16 And tried again ... no go. In short, I can interactively create the new partition, but it disappears on reboot. I suspect that the problem has to do with not being able to commit my changes, but I cannot seem to figure out why this is so. And yes, I've tried this in single user mode as well. -- ---------------------------------------------------------------------------- Tim Daneliuk tundra@tundraware.com PGP Key: http://www.tundraware.com/PGP/
