this all makes sense and sounds a bit like a solr setup :-)
I have now added the third node as a peer

That indeed allow me to mount the share manually on node2 even if node1 is

You would need to ensure that at least two of the nodes are up in the
cluster in this case.
Atin, why? I've never had that restriction.
It sounds to me like the mount's trying to happen before any bricks are
available and/or glusterd is listening.
Is there a particular reason for this, or is it a misconfiguration?

This is exactly what I gave as an example in the thread (please read
again). GlusterD is not supposed to start brick process if its other
counter part hasn't come up yet in a 2 node setup. The reason it has
been designed in this way is to block GlusterD on operating on a volume
which could be stale as the node was down and cluster was operational
earlier.
For two node deployments, a third dummy node is recommended to ensure
that quorum is maintained when one of the nodes is down.

Vijay
Have the settings changed to enable server quorum by default?
