[linux-lvm] lvextend origin

[Tom Assmuth]

hi there, 

im trying to get lvm-snapshots working with lvm2 and debian. 
But i think this is a general question, too.

so here my question: 

Is it possible to lvextend an origin lv (of snapshots) with lvm2 ?

i got the message: "Snapshot origin volumes can be resized only while
inactive: try lvchange -an"

that is strange to me, because with lvm1 that's not even a point to
mention.

Is it necessary to deactivate the origins, because the snapshots are
rw by default? (Well that's the only difference to me) - if "yes", how
can i create a read-only snapshot?

Thanks 4 any hints! 

tom
