...as we try to use 2 or more we get issues. It looks the same as bug 636: http://oss.oracle.com/bugzilla/show_bug.cgi?id=636 I posted my cluster.conf and command line results there. I'm including them here in the hopes that someone on this list can offer a shorter solution than recompiling the o2cb_ctl (which we have in process). Thanks in advance for any and all help. Here's my post on the bug: seems like we're back to having this bug again. I'm posting both cluster.conf and the error that happens at the command line. <cluster.conf> cluster: node_count = 2 na...

We have a test 10gR2 RAC cluster using ocfs2 filesystems for the Clusterware files and the Database files. We need to increase the node slots to accomodate new RAC nodes. Is it true that we will need to umount these filesystems for the upgrade (i.e. Database and Clusterware also)? We are planning to use the following command format to perform the node slot increase: # tunefs.ocfs2 ?N 3

...e OCFS2 Clustering Services] O2CB is comprised of a simple node manager, heartbeat, TCP protocol, and DLM. The basic steps in startup are as follows: 1) Load the nodemanager, heartbeat, and tcp modules 2) Mount the nodemanager and heartbeat pseudo filesystems. 3) Load the cluster information via o2cb_ctl. This adds all the known nodes to the nodemanager's psuedo filesystem. 4) Load the DLM module. 5) Load the OCFS2 module. 6) Mount an OCFS2 filesystem. The /etc/init.d/o2cb program is responsible for handling steps 1-3 during the boot of a machine. If you are running from the source tree,...

I looked around, found older post which seems not applicable anymore. I have a cluster of 2 nodes right now, which has 3 OCFS2 file systems. All the file systems were formatted with 4 node slots. I added the two news nodes (by hand, by ocfs2console and o2cb_ctl), so my /etc/ofcfs/cluster.conf looks right: node: ip_port = 7777 ip_address = 192.168.201.1 number = 0 name = dbcl1n1 cluster = dbcl1 node: ip_port = 7777 ip_address = 192.168.201.2 number = 1 name = dbcl1n2 cluster...

Hi everybody, My problem is that I want to add a new node to an existing RAC with ocfs2, without stop the database. If I add a new node to an existing ocfs cluster, do I need to stop the ocfs in the others nodes of the cluster? I've tried to do it without stop the ocfs in the others nodes but I get the following error:

Hi, I was looking for why one of the nodes could not mount OCFS again, then I found this path: /sys/kernel/config/cluster/r0/node/ Which I have folders related to my servers, then I noticed that node1 (which is working with OCFS2) did not update node2 IP address. The file I am talking about is: /sys/kernel/config/cluster/r0/node/raid2/ipv4_address Example: root at
