O2cb_ctl Configuration Error Discovered While Populating Cluster Ocfs2
/webdata. Check 'dmesg' for more information on this error. Maybe the problem: 1: The firewall is open, not closed, shielding the heartbeat port 2: Each node of the /etc/init.d/o2cb configure configuration of different causes. loading filesystem "ocfs2_dlmfs": unable to load filesystem "ocfs2_dlmfs" 3: A node is in the mount, another node just configured, restart the mount.ocfs2: unable to access cluster service while trying to join the group OCFS2 service at this time as long as the cause, even a node restarting the service can be completed mount. 4: ocfs2 fstab SElinux did not shut down. The following is a case: [root@test02 ~]# mount -t ocfs2 /dev/vg_ocfs/lv_u02 /u02 mount.ocfs2: Transport endpoint is not connected while mounting /dev/vg_ocfs/lv_u02 on /u02. Check 'dmesg' for more information on this error. This error is due to the node OCFS configuration when the value of O2CB_HEARTBEAT_THRESHOLD is not the same result. I use /etc/init.d/o2cb configure in fact, each node have values are the same, but the first node forget to restart o2cb, the search for a long time to find. Then of course is to have the MOUNT OCFS directory UMOUNT off, the wrong again: [root@test01 u02]# umount -f /u02 umount2: Device or resource busy umount: /u02: device is busy umount2: Device or resource busy umount: /u02: device is busy It should use the /etc/init.d/ocfs2 stop and /etc/init.d/o2cb stop off OCFS2 and O2CB UMOUJNT, then OCFS2 and O2CB start after the other nodes will be able to MOUNT OCFS.

explains the step by step process of unable to adding a Node to 11g RAC Cluster. In this process, I am going to add a single node (node2-pub) to single node RAC cluster online without affecting the availability of the Existing RAC Database. Existing RAC Architecture: RAC Nodes: Node 1: Public: node1-pub Private: node1-prv Virtual: node1-vip ORACLE_HOMES (Local on Each Node); CRS_HOME: /u01/app/crs DB_HOME: /u01/app/oracle/product/11g/db_2 o2cb_ctl configuration error ASM_HOME: /u01/app/asm/product/11gr1 Database / ASM:: DB Name: test DB Instances: test1 on node1-pub ASM Instances: +ASM1 on node1-pub. Node to be added: node2-pub Assumptions: MAXINSTANCES in controlfile is set to atleast 2. Node node2-pub is physically connected to the Cluster. Same Linux OS version as node 1 is installed on the new node Tasks List (to be executed in Order): Provision the New Node (node2-pub) Install CRS Install 11g RAC DB Software for ASM_HOME on Node2-pub Add LISTENER on node2-pub Add DB Software for ORACLE_HOME on node2-pub Add ASM Instance +ASM2 on node2pub Manually Add DB Instance teste on node2-pub Manually.
