[jboss-dev-forums] [Design of Clustering on JBoss (Clusters/JBoss)] - Distributed Lock Mechanism

Hi guys, For Hibernate Search, I'm in need for a DLM (Distributed Lock Mechanism). Basically a way to acquire a lock, do some stuff and release a lock clusterwise. This is something that can be available and built on top of JGroups. I've talked to a RH instructor and we discussed the DLM available in GFS (Global file System). To summarize: - there is a quorum (each node having a weight) - a subset of the cluster is considered free to work if it has quorum/2+1 - when a node ask for a lock, it informs everybody, and everybody has to agree on the lock acquisition - if a lock is acquired the demanding node is responsible for managing the lock - if a node is playing the bad guy or has been cut from the majority, it reboots itself or is made rebooted hoping for a recovery This implementation is not really fully self configurable (entering and leaving the quorum part might have to be manual) Do you think we can build something similar as a common project for JBoss, I need it but most likely, some other projects need that too. I'm pretty open to the feature support as well. There may be something available already? Thoughts? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4003554#...
