Server :: Unable To Configure Slave Nodes On Rocks Cluster?
May 28, 2010
I am trying to setup Rocks Cluster on a Cluster containing 1 Master node and 23 slave nodes connected via a Switch. The master node's eth1 is connected to public IP and eth0 is connected to the slave nodes via the switch.
I was able to install the Rocks cluster on the machine, I configured the IP for master through DHCP. When I run the command 'insert-ethers' on the master node, it doesnot get me any slave nodes.
setting up the Rocks cluster on all the nodes?

My requirement is to route ssh sessions from a single head node to multiple slave nodes. So what i want is, for a client there is just one point of entry (master/head node) to ssh into, it evaluates the load on the slave nodes connected on to internal network and routes the ssh session, kind of a ssh load balancer. what open source solution i can apply for my problem?

I have tried using LVS piranha, it works well for http and https load balancing but not for ssh load balancing.

I have an annoying problem with a 2 nodes cluster that I don't understand.
One of my server is totally shutdown.
When I start cman after a reboot on the other server, it hangs on "Starting fencing...". The process which is actually hanging is : /sbin/fence_tool -w -t 300 -m 45 join
When I start this program manually, I get this output :
# /sbin/fence_tool -w -t 300 -m 45 join
Waiting for all 2 nodes to be members
Waiting for all 2 nodes to be members
Waiting for all 2 nodes to be members
Waiting for all 2 nodes to be members
(and so on...)
What I don't understand is why the fence_tool program wait for the 2nd node to join the cluster and don't fence the other node.
Here is my cluster.conf :
<?xml version="1.0"?>
<cluster name="ctpsrv-bdd" config_version="7">
<fence_daemon clean_start="0" post_fail_delay="0" post_join_delay="20"/>
<cman expected_votes="1" two_node="1"/>
[Code]....
Would it be a good idea to edit the cman startup script and remove the "-w" option of command fence_tool join, so the command do not hang up ?

I am trying to build GFS2 cluster with 2 or 3 Fedora 14 nodes, but I've encountered some problems from the start. First luci does not work at all in Fedora 14. There is no luci_admin and even if I manage to start luci service, I get a blank white screen when I try to open it from the browser. I've googled a bit and found that I'd might be able to setup GFS if I manage to build cluster.conf manually and start the cluster suite, but I cannot find documentation on how to create cluster.conf anywhere. If anyone knows how to setup GFS2 without a cluster suite or how to configure cluster.conf.

I'm having a very strange problem with red hat cluster. After testing it in the lab, I tried to install a new cluster and received the following error: cman not started: Cannot start, cluster name is too long or other CCS error /usr/sbin/cman_tool: aisexec daemon didn't start I've checked the internet for that error, but nothing. I decided to to take the example from cluster.conf man, which looks like that :

And still I get the same error. I can find my servers both from DNS (FQDN and short name) and they also appear in /etc/hosts.

I am new to clustering. I have created this scenario on VMware Workstation after reading numerous links and videos.
Few of them are
[url]
[url]
[url]
Code:
I am using a shared GFS2 filesystem mounted on /data for this purpose which is from openfiler.
Code:
I am trying to create a HTTP cluster so that if in case of one node fails
- Shared partition (/data) in my case gets mounted on the other node
- Also, HTTP services can be started on the other node.
/data has the index.html file which is read by HTTP. Also, I have configured HTTP such that it only listens to 192.168.1.100 (shared IP) on port 80.
Code:
I have configured the cluster, service "sharedIP" which has IP 192.168.1.100; I took help of this doc.
Code:
Member Status: Quorate
I have tested the service sharedIP failover by powering off the machines one by one.
I used the below command for failover
Code:
Now, I need to try running apache from shared IP 192.168.1.100 which will fetch file from /data/index.html
I tried no. of times to configure service and resource for apache.
But somehow, it is not happening. My apache bin is /usr/local/apache/bin/apachectl start|stop
I have given such long info to help some other newbie. I will certainly write a HOW-TO for this.

I am trying to do the cluster storage with the Rock Cluster storage operating system . I have install the rock cluster on the main server . and I want to connect the client with the PXE boot . when I starting the client then it boot from the PXE boot into the mode of compute node. but it ask the where is to be stored the I have give the path..then server says that not able to find the directory path.
Steps:-
1) insert-ethers
2) client is started with the PXE boot.
3) it detects the dhcp .
4) At last it demand where is to be started by cd-rom, harddisk ,nfs etc.
then I started with the nfs and I have given the lanIp of server.and server is detecting the client but client is not finding the filesystem directory. into export partition directory but it is not taking path.
PATH:-
/export/rock/install it is not finding this path then it is not able to start the o/s from PXE boot..Is there any solution and manual of rock or anyother solution then u can reply to me...

I have set up a nis slave server on Fedora 14. It was set up on a laptop so that the user can log in when he is at home (no NFS, local home dir). However, whenever the eth0 is disconnected, ypbind fails.
I have tried the same setup on a RHEL 4 (configured it as a slave server) against the same master nis as on the Fedora 14. Disabling eth0 on it however does not fail ypbind.
