Is the minimum 5 seconds, or can i go even lower, like 1 sec? thanks cluster.conf parameters (eg): <cman hello_timer="1" deadnode_timer="10"/> The number are integer seconds so 1 is the smallest value you can have. Before you put that into production though, check it under load because high I/O or network loads can cause spurious node "failures". see /proc/cluster/config/cman for all the changeable values. -- Patrick Registered Address: Red Hat UK Ltd, Amberley Place, 107-111 Peascod Street, Windsor, Berkshire, SL4 ITE, UK.
