Dear hackers,
I've just committed a first geomified version of vinum, surprisingly
called geom_vinum.
Please read on before you all go out and run your cvsups, as
there are some things to note:
*) It's not yet connected to the build, as it is not really finished
yet, but I wanted to give you something to play around with. Some
functions of the 'old' vinum aren't implemented yet, some will never
be, as they aren't needed anymore, or where I don't see a real reason
to bring them over.
*) As if you wouldn't have guessed: don't use it on important data.
It probably won't set your box on fire, but you never know.
*) You can use it on your existing vinum setup, as it uses the same
on-disk configuration format. But don't run both vinum and
geom_vinum and the same time.
*) You shouldn't need to label any desired slice as type vinum with
bsdlabel(8) anymore. In theory, you should be able to dedicate a
whole disk to geom_vinum (i.e. 'drive bigstuff device /dev/ad2').
*) Don't unload the module if you have valid objects in your setup. Due
to a bug in GEOM this will either panic or deadlock. You can pick up
a patch at <http://people.freebsd.org/~le/geom_subr.c.diff>; and
rebuild your kernel, then you can safely unload the KLD again.
*) If you want to test it:
cd /sys/modules/geom/geom_vinum
make && make install
cd /usr/src/sbin/gvinum
make && make install
You can then run 'gvinum' (which will load the KLD) and create
objects like in the 'old' vinum. The volumes will appear as devices
in /dev/gvinum/.
Bug reports, suggestions, critics and flames are happily awaited, even
more so when they have patches attached. :-)
Thanks,
le
