[Ocfs2-users] Re: Remove a node from cluster.conf

[Saranya Sivakumar]

Eventually I want the cluster.conf to look like following:

node:
        ip_port = 7777
        ip_address = 10.10.11.180
        number = 0
        name = nodea
        cluster = ocfs2

node:
        ip_port = 7777
        ip_address = 10.10.11.181
        number = 1
        name = nodec
        cluster = ocfs2

cluster:
        node_count = 2
        name = ocfs2

Please advice what's the best way to achieve this.

nodec is getting prepared to be added to the RAC cluster, and right now doesn't have clusterware or RAC db installed on it.
I am planning to use cloning to install clusterware and RAC from nodea to nodec once I have ocfs2 setup.

Subject: Remove a node from cluster.conf

Hi All,

I would like to know the steps to remove a node from cluster.conf file.
We had a two node RAC from which we removed one of the nodes.
But, we haven't updated the cluster.conf file to reflect this change. We are using ocfs2 1.2.3.

The current cluster.conf is

cat /etc/ocfs2/cluster.conf
node:
        ip_port = 7777
        ip_address = 10.10.11.180
        number = 0
        name = nodea
        cluster = ocfs2

node:
        ip_port = 7777
        ip_address = 10.10.11.182
        number = 1
        name = nodeb
        cluster = ocfs2

cluster:
        node_count = 2
        name = ocfs2


I want to remove nodeb from cluster.conf , so that I can add nodec to this cluster.

>From what I have read so far, I see this can't be done dynamically and requires the cluster to be shutdown.
Could someone please confirm is the following steps are correct?

1) Shutdown OEM
2) Shutdown database
3) Shutdown ASM
4) Shutdown CRS
5) Shutdown listener
6) Shutdown OCFS2 cluster
7) Make changes to cluster.conf
8) Reboot machine and check if everything comes back up properly.
