[Ocfs2-users] mixed mode mount options?

[Sunil Mushran]

The node doing the ro mount is a full member of the cluster. Yes, it  
will participate in cluster activities including replaying a dead  
node's journal, etc. So it is not the spectator node that gfs2, I  
believe, has. I've never quite understood how a spectator node can  
maintain cache coherencies.... other than by disabling all caches and  
hitting disk on every read. Not sure if gfs2 does that or what level  
of coherency it guarantees the user.
