RedHat build Cluster problems

Problem 1: When the Cluster package is installed, an error is reported when cman is started. & ldquo; cmannotstared: two_nodesetbuttherearemorethan2nodes/usr/sbin/cman_tool: & rdquo; solution: the above problem is that the cman_tool command cannot be found at the node. This is because the Cluster package is not fully installed and the support for openais-devel and other related packages is missing.

Problem 1: When the Cluster package is installed, the error "cman not stared: two_node set but there are more than 2 nodes/usr/sbin/cman_tool:" is reported when the cman is started :"

Solution: the above problem is that the cman_tool command cannot be found at the node, because the Cluster package is not fully installed and lack support for openais-devel and other related packages, "yum groupinstall Cluster *" should be used for Cluster installation. If RedHat6.0 or a later version is installed with "yum groupinstall High *", the package installation integrity can be ensured.

Problem 2: When LUCI is used to create a New Cluster, The following Error occurs: "The following errors occurred while creating cluster" cluster ": Error Handling header from Oracle01: 11111, Error handling header from oracle02: 11111 "error.

Solution: Make sure that the Service Ricci is in the startup status on the node. The created Cluster name is unique and never used. Disable iptables.

Question 3: When you use LUCI to configure the Fence card, there is no ipmi.

Solution: In RedHat5.0, you can use system-cluster-config to set Fence. In the settings, you can select ipmi in Fence. In RedHat6.0, you can modify the/etc/cluster. conf configuration file.
