Just an update. On Debian Suqeeze, I was able to compile and install Cluster3 without rgmanager on Corosync 1.4.2:
./configure --prefix=/usr/local --without_rgmanager --corosyncincdir=/usr/include/corocync --corosynclibdir=/usr/var/lib/corosync openaisincdir=/usr/include/openais --corosyncbin=/usr/sbin/corosync I hope getting dlm and fence will be just as easy. Nick.
