<div dir="ltr">hi in 2-node cluster you don't need a quorum disk , there is a 2-node cluster option that will added to the cluster.conf , and the cluster will be functional quorate and everything , think of it if you have 2 nodes only . regarding your problem , is the problem occuring on a specific node , or on both , if on a specific node , then check connectivity with shared disk , also how are you shutting down the cluster ( hard shutdown? ) , simultaneously or at the same time, .... it all maters ?? also check the fencing devices is the fencing occurring correctly ( did you tried to unplug network cables from one node and observed behavior )???? many parameters to check , my recommendation is to troubleshoot step by step starting with the basics ( hardware .. ) and on the way up . <div class="gmail_quote">On Fri, Sep 24, 2010 at 7:38 PM, emilio brambilla <<a href="mailto:emilio@inet.it">emilio@inet.it</a>> wrote: <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> hello, I have a 2 node cluster with qdisk quorum partition; each node has 1 vote and the qdisk has 1 vote too; in cluster.conf I have this explicit declaration: <cman expected_votes="3" two_node="0"\> when I have both 2 nodes active cman_tool status tell me this: Version: 6.1.0 Nodes: 2 Expected votes: 3 Quorum device votes: 1 Total votes: 3 Node votes: 1 Quorum: 2 then, if I power off a node these value, as expected, changed this way: Nodes: 1 Total votes: 2 and the cluster is still quorate and functional. the problem is if I power off both the node and them power on only one of them: in this case the single node does not quorate and the cluster does not start: I have to power on both the node to have the cluster (and services on the cluster) working. I'd like the cluster can work (and boot) even with a single node (ie, if one of the node has hw failure and is down I still want to be able to reboot the working node and have it booting correctly the cluster) any hints?
