Hi Bob I've checked the clushutdown script , and it is explicitely written iin the script : "This NEVER needs to be run in two member clusters" And I'm only in case of two member clusters ... So, I think that finally the shutdown sequence to apply remains : stop all HA applications via clusvcadm stop all CS4 services (rgmanager/fenced/cman/ccsd) and stop the node. This way, there is no risk to have fence sequences performed by the CS4, and no failover attempt. Am I right ? Remains only the problem that cman often fails to stop (see previous email) Regards Alain -- mailto:Alain.Moulle@xxxxxxxx +------------------------------+--------------------------------+ | Alain Moullé | from France : 04 76 29 75 99 | | | FAX number : 04 76 29 72 49 | | Bull SA | | | 1, Rue de Provence | Adr : FREC B1-041 | | B.P. 208 | | | 38432 Echirolles - CEDEX | Email: Alain.Moulle@xxxxxxxx | | France | BCOM : 229 7599 | +-------------------------------+-------------------------------+ -- Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
