The two are more or less unrelated. Raw devices in clumanager are used for storing internal clumanager states, and have a minimum size of 10mb each. Components of GFS (CCA, pool volumes, file systems, etc.) can not be used atop of those two raw devices, but may be used atop of the same GNBD volume (with partitioning, of course!). > 2. rgmanager, how is this different from the cluster software's > fallback (failback?) domains and members taking over a service and a > related floating ip from a fallen member? > again thanks for your time rgmanager ~= clumanager+1 Rgmanager is similar to clumanager, but is a bit more modular: it supports on-the-fly reconfigurations of services and uses CMAN+DLM or gulm for the infrastructure instead of providing its own. -- Lon
