dumpon and gmirror = ioctl(DIOCSKERNELDUMP): Operation not supported

[Marcus Grando]

Hi,

I try run dumpon on swap partition in gmirror disk. But that's not 
possible. This error occurs:

# dumpon -v /dev/mirror/datas1b
dumpon: ioctl(DIOCSKERNELDUMP): Operation not supported

It's possible to use dumpon with gmirror disk? Any patch?

Thanks
