The GEOM code in the kernel puts some extra sanity checks in. I bet some partition on the disk is being used for something. Try this: # mount | grep ad2 # swapinfo | grep ad2 If any of those return anything, swapoff/umount the relevant partitions. Also, if you install /usr/ports/graphics/graphviz, you can get a diagram of what GEOM thinks is in use: # sysctl -b kern.geom.confdot > temp.dot # dot -Tgif -o temp.gif temp.dot Then view temp.gif with your favorite gfx program. Look for 'locks' info. If you're running 4.x, or if this fails, check permissions on the device.
