Hi, I am right now working on ci-linux.sf.net project. The goal is to get the code ready so that projects like GFS and OCFS2 can start using the framework. CI/ICS allows to build cluster service without worrying about the transport mechanism used. With the OpenSSI project we had both IP and infiniband transport and i belive it should be easy to implement one using sctp or TIPC. You can see the result of my work here http://git.openssi.org/~kvaneesh/gitweb.cgi?p=ci-to-linus.git;a=summary Different components of CI is explained here http://ci-linux.sourceforge.net/components.shtml I have dropped CLMS and CLMS key service. I am looking at using CMAN/configfs for doing the cluster membership part. Registering new cluster service is explained here. http://ci-linux.sourceforge.net/enhancing.shtml here also you can drop the CLMS part . This link explains how to write new cluster service. http://ci-linux.sourceforge.net/ics.shtml A simple example is below http://git.openssi.org/~kvaneesh/gitweb.cgi?p=ci-to-linus.git;a=blob;h=8282ad15da09901f4cd4bdd62490766458d1cebf;hb=f7e456933b9868486c014a83e473f647149a71f6;f=include/cluster/gen/icssig.svc http://git.openssi.org/~kvaneesh/gitweb.cgi?p=ci-to-linus.git;a=blob;h=1004328006021f5287bb543abc7d15e51964eae6;hb=688587ead9ce2d26070ca051323769cd76c91185;f=include/cluster/gen/icstest.svc Please follow up at sic-linux-devel@xxxxxxxxxxxxxxxxxxxxx -aneesh -- Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
