When I try the commands below (which apparently work on 2.2.6) I get the
following error:
[morden|root] 23:03 ~ disklabel /dev/rvn1 | disklabel -R -r vn1 /dev/stdin
disklabel: ioctl DIOCGDINFO: Inappropriate ioctl for device
sector size 0
vn1 is being used because vn0 is used as a swap device.
My kernel has the following:
pseudo-device vn 2 #Vnode driver (turns a file into a device)
and is up-to-date with -current.
Any ideas?
Kris

The following works for me on 2.2.6R:
dd if=/dev/zero of=vn0.file bs=1m count=200
vnconfig -c /dev/vn0 vn0.file
disklabel /dev/rvn0 | disklabel -R -r vn0 /dev/stdin
disklabel -r -e vn0
newfs /dev/rvn0a
Maybe there's an easier way though...
