I just installed 7.3-RC2 amd64 on new server.
I created slice s1 (80GB on disk ad4 (500GB), then partitions for system
(/, swap, /var, /usr, /tmp) by sysinstall.
After base install I created gmirror gm0 as usual (I did it many times).
Now I am no longer in datacenter and have only ssh access to this server
and I need to create slice s2 with some partitions for data storage, but
fdisk failed.
fdisk -u /dev/mirror/gm0
At the end, I got this error:
Should we write new partition table? [n] y
fdisk: Geom not found: "gm0"
fdisk: Failed to write sector zero
Fdisk failed even if I used
sysctl kern.geom.debugflags=16
Question #1 - why 'Geom not found: "gm0"'?
Question #2 - is there any way to create slices + partitions on unused
space if system is booted from this device?
Or is the only way to boot it from some LiveFS / fixit?
I found the same question on this list, but without reply

I hope somebody can help / explain it.
