Thanks for your feedbacks. The rsync method is very simple to implement on 2 nodes ...but does it scale with 5 nodes or so ? If a modification is done on one node, how would rsync propagate it on every other ? I am considering one of these 2 options : - mounting a filesystem (iSCSI LUN probably) containing the configuration or - having a central configuration system like puppet to ensure that the config is consistent everywhere (I thought about this one today) second option seduces me a lot. It's more work to do, but it would help to have a consistent cluster node, and would make adding new node to the cluster trivial operation. jonathan -- IUEM - Service Informatique rue Dumont D'Urville Technopôle Brest-Iroise 29280 Plouzané France tel: +33 2 98 49 87 94
