Crap - it is fighting you, yes - looks like the startup script has tried 
to build an osd for you using ceph-disk (which will make two partitions 
by default). So that's toasted the setup that your script did.

Growl - that's made it more complicated for sure.

If you re-run your script you'll blast away the damage that 'service' 
did :-) , and take a look at /etc/init.d/ceph to see why it ignored your 
osd.0 arg (I'm not sure what it expects - maybe just 'osd'). Anyway 
experiment.

You can always start the osd with:

$ sudo ceph-osd -i 0

which bypasses the whole system startup confusion completely :-)

Cheers
