Hi, I follow the steps below to use fence_xvmd in RHEL5; (1) configure dom0 like a 1-node cluster (2) Add "<fence_xvmd/>" to cluster.conf in dom0 as a child of the "<cluster>" tag. (3) dd if=/dev/urandom of=/etc/cluster/fence_xvm.key bs=4096 count=1 (4) scp /etc/cluster/fence_xvm.key root virtual_node_1:/etc/cluster (5) scp /etc/cluster/fence_xvm.key root virtual_node_2:/etc/cluster (6) Start cman on dom0 - this should start fence_xvmd for you However, I encounter the following errors while running "fence_xvmd -fddddddddd" on the dom0 node and "fence_xvm -H <domain_name> -o null" on one of the guests; Hash mismatch: PKT = 94598bef00f4bc3198032800b714bca59581404f8ca2e9c8ea8bb1119840e83c00000000 00000000000000000000000000000000000000000000000000000000 EXP = 85168eb74638ff044c31a4749dba9cc0b9c66e319398dcc8cd97ee4cf1e3936800000000 00000000000000000000000000000000000000000000000000000000 Key mismatch; dropping packet Any idea why?
