[9fans] fs(3) issues ('clear' missing and mirror question)

Dear List,

1)
I have been playing with fs(3). Unfortunately the clear command
mentioned in the man page does not seem to exist.

cpu% echo clear > /dev/fs/ctl
echo: write error: unknown control message "clear"

whereas fs(3) says:
clear
               Discard all fs device definitions.

One of each is wrong here ;)

2)
I wanted to use fs(3) to setup mirrored venti arenas, and indeces.
Now with fs I only get one device after a 
echo mirror m0 /dev/sdC1/data /dev/sdD0/data > /dev/fs/ctl

I have read in earlier threads that it is possible to disk/part the
m0 device. How can I specify the partitions later on? Also This
seems to fail:

cpu% disk/prep -a^(isect arenas fscfg) /dev/fs/m0 > /dev/fs/ctl 
no plan9 partition table found
fscfg 1
arenas 558164159
isect 27908208
' fscfg                   0 1            (1 sectors, 512 B )
' arenas                  1 558164160    (558164159 sectors, 266.15
GB)
' isect           558164160 586072368    (27908208 sectors, 13.30
GB)

Is this supposed to work? Doing it a second time disk/part tells me:
cpu% disk/prep -a^(isect arenas fscfg) /dev/fs/m0 > /dev/fs/ctl
partitions already exist; not repartitioning
>>> q

The '>/dev/fs/ctl' part comes from a mail from erik (Message-ID:
2cb5e9b012d84b84ab0216685114e141 () coraid ! com
)

Should I mirror each partition separately then?

Thanks for your precious time,

Christian
