Can't *write* to a hard disk, not even a slice using fdisk(8).

Ok no problem, I changed it this way :
# sysctl kern.geom.debugflags=16
kern.geom.debugflags: 1 -> 16
But it seems to change *absolutly nothing*... :(

I don't think so, /dev/ad8 has no problem and is actually in active use.
Let me be more precise here:
The "system" (/, /tmp, /usr and /var) is mounted on a mirror represented
by /dev/ar0 made with /dev/ad4 and /dev/ad6.
The "data" (/home) was previously mounted on the device /dev/ar1 which was
made with /dev/ad8 and /dev/ad10.
Because /dev/ad10 seems to have a problem I made a backup, broke the
mirror seen as /dev/ar1 and simply put /home on /dev/ad8 - freshly
