Ever since we have installed OCFS2, we have had extremely slow
performance in the ocfs2console. It can take us over 30 minutes to do
the simplest tasks.
We do not have this type of performance with other xwindows applications
on our server.
Does anyone have any performance improvement
No, mounted.ocfs2 -d comes back in less than 5 seconds.
Thanks again,
Reid

We are having trouble getting the 2nd node in our 2 node RAC
configuration to have an active O2CB heartbeat. We have our OCR and
voting disks on an OCFS2 mount point, so we cannot bring up Clusterware
on this node.
I'm at a loss as to what the issue is. It was running fine for a few
weeks,
When I launch ocfs2console, it takes a few minutes until you can
actually click on anything in the ocfs2console gui.
Each click in the console takes at least 5 minutes.
For example, if I want to format a device, I have to wait for the
console to come up (3 minutes or so), then I select the
The connect requests are not getting through. Do you
have any firewalls setup? Is iptables running? If so, either
shut it down or allow traffic on the o2cb port.

I have a 2 node cluster setup but am at a loss as to why I cannot
mount a shared ocfs2 filesystem on both nodes being shared by iSCSI?
Am I wrong in understanding that this can be achieved?
I am using OpenAIS under SLES 11, any comments will be helpfull.
Thanks,
Sam.
Which cluster stack are you using? o2cb or pacemaker?

Usually the server reboots on fatal errors.
You can check the /var/log/messages and search for reboots or see
`dmesg` output for non fatal errors or warnings.

Yours is a pretty normal configuration
No, iptables is shutdown and disabled. No firewalls.
[r...@nyclx1 ~]# service iptables status
Firewall is stopped.

Do:
$ tcpdump -i ethX -s 2500 -ttt 'port '
on both nodes. Replace ethX with the appropriate interface.
Then issue the mount command on node 1. Do you see the traffic
on node 0?

We can bring up the ocfs2 cluster on 1 of 2 nodes only. So, it appears
that it's not specific to only one specific node. Right now we have the
ocfs2 heartbeat operational on node2 (node1 in the cluster.conf).
Here are the results of the mount and tcpdump.
[r...@nyclx1 ~]# mount -t ocfs2
Did you have tcpdump running on a terminal when you attempted
the mount on another terminal? Is the interface and port correct?
It is one thing to not see the packets on the nyclx2. But what
confuses me is that there is no traffic on nyclx1 too.

Yes, I had tcpdump running in separate sessions on both servers.
The port is correct. Here is the cluster.conf.
node:
ip_port =
ip_address = 192.168.0.218
number = 0
name = nyclx1
cluster = tiaa
node:
ip_port =
ip_address =
Do on both nodes:
$ netstat -ta --numeric-ports
Maybe port is already in use.
Check your setup again. Ensure cluster.conf is the same on both nodes.
And that the ips are correct. That tcpdump was capturing
the traffic on the correct interface. etc. etc.
