Snapshots most assuredly does NOT work when you have the cluster LVM enabled.  Here's a quick example:

[root at cobalt ~]# lvcreate --snapshot --size 1G --name compaq-snap /dev/software/compaq
   Clustered snapshots are not yet supported.
[root at cobalt ~]#

At the Red Hat summit back in the summer I spoke with a lot of the cluster developers, this is something that is apparently a pretty 
hot deliverable for them.  I know I sure want it back, but I haven't heard anything about when it will be available on a clustered 
system.
