[Linux-cluster] not fencing a voting node dangerous?

To prevent the "two nodes fencing each other" scenario of a 2-node GFS 6.1 cluster, I have set up a 3rd node as a voting node:
- All the packages from RHCS 4
- lvm2-cluster RPM (if clvmd is not running on the 3rd node, lvm commands fail)
- no fencing device for this node.
- no access to the shared storage

My question is about fencing of the voting node: Since it will not be accessing the shared storage, can I have it running without a fencing device? The voting node is running a number of other services (not highly available) and having it fenced now and again would be really inconvenient.

Under what circumstances would not having this node fenceable be dangerous?
