Hello,
           I need help to install and configure Redhat Cluster. Need following thing for same.
1. I need documents which will help me to install and configure same.
2. From where can I download clusting software.

Hi Mike,

1. I recommend "service ccsd stop" rather than killall ccsd.
2. In theory, this script should not be necessary on a RHEL, Fedora Core 
or centos box
    if you have your service scripts set up and chkconfig'ed on.  When 
you do
    /sbin/reboot, the service scripts are supposed to run in the correct 
order
    and take care of all this for you. Shudown should take you to 
runlevel 6,
    which should run the shutdown scripts in /etc/rc.d/rc6.d in the Kxx 
order.
    The httpd script should stop that service, then the
    the gfs script should take care of unmounting the gfs file systems 
at "stop".
    The clvmd script should take care of deactivating the vgs.  And the 
Kxx numbers
    should be set properly at install time to ensure the proper order.
    If there's a problem shutting down with the normal scripts, perhaps 
we need to
    file a bug and get the scripts changed.

There is no assumed correlation between the NIC(s) rgmanager uses for
services and the NIC(s) CMAN uses; many people use one network for
cluster traffic and another for service related traffic.  In this case,
a service failure due to a NIC link failing is far less of a problem:
The service fails, and it moves somewhere else in the cluster.

More generally, health of part of an rgmanager service != health of a
node.  They are independent, despite sometimes being correlative.

I think it's interesting to point out that CMAN, when run in 2-node
mode, expects the fencing devices and cluster paths to be on the same
links.  This has the effect that whenever you pull the links out of a
node, that node actually can not possibly fence the "good" node because
it can't reach the fence devices.  It sounds like you altered your
configuration to match this using vlans over the same links.

As a side note, it would also be trivial to add a 'reboot on link loss'
option to the IP script in rgmanager. *shrug*.

Can I configure a quorum disk giving it only a vote option and no heuristic parameters?
I.e.

in /etc/cluster.conf can i configure quorum disk in this way?

<quorumd interval="1" tko="10" votes="3" label="Quorum-disk">

I wouldn't think this should matter, but it does depend on how they're
configured.  It should look something like:

  <service>
    <fs>
      <nfsexport>
        <nfsclient/>
        ...
      </nfsexport>
    </fs>
    <clusterfs>
      <nfsexport>
        <nfsclient/>
        ...
      </nfsexport>
    </clusterfs>
    <ip/>
  </service>

They shouldn't - as long as the exports don't overlap.

You can.

If you can come up with good heuristics, even if it is just pinging  
your network gateway, it is very helpful at keeping your cluster  
functional.  Without this, a partition of your cluster will remain  
quorate, but not necessarily the partition that can still be reached  
from the Internet (or wherever its services are accessed from).

Good catch.

NODE_ID_NONE isn't in RHEL5[0]/HEAD right now; so the checks should be
">= 0" rather than "!= 0".  NODE_ID_NONE was (uint64_t)(-1) on RHEL4.

I have seen this behavior.  It is not strange to me.  This is only  
strange to people who do not understand how quorum systems work.

This is *NOT* a workaround for lack of communication.  clurgmgrd is  
responsible for starting and stopping services.  Fencing is  
responsible for keeping nodes running.  clurgmgrd does not have the  
information and is not the right service to handle this.

The problem is that you have a two node cluster.  If you had three  
nodes, this would not be an issue.  In a two-node cluster, the two  
nodes are both capable of fencing each other even though they no  
longer have quorum.  There is mathematically no other way to have a  
majority of 2 nodes without both of them.

The Quorum Disk allows the running nodes to use a heuristic--like the  
ethernet link check you speak of (or a ping to the network gateway  
which would also be helpful).  This heuristic allows you to  
artificially reach quorum by giving extra votes to the node that can  
still determine that it is okay.

The moment that a node fails for any reason other than an ethernet  
disconnection your workaround falls apart.

If some "Central Bank" is truly your customer, then you should be  
able to obtain a third node with no problems.  Otherwise, the Quorum  
Disk provides better behavior than your "workaround" by actually  
solving the problem in a generally applicable and sophisticated way.

This is a configuration problem.  If you desire not to be laughed at  
learn how to configure your software.  Also, for what its worth, I  
don't use bonding on my machines due to the switches I utilize (I use  
bridging instead), but I would recommend keeping this for reliability  
of the ethernet, as it is an important failure case.

Is there an upper bound for UID/GIDs? 

Repeatedly I have seen GFS quota file problems when I have had UIDs

There's a problem with the 'list' option in gfs_quota tool with large 
UID/GIDs. This problem has been fixed in RHEL4,

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=210362

GFS1 and GFS2 in RHEL5 still have this issue and a solution needs to be 
worked out.
What other problems are you referring to? A bugzilla would help.

This is actually my latest. While it does not *seem* to work at times, it does 
take the node out of the cluster cleanly. I say seem because it tells me that 
the node is still in the cluster yet it's not.

# more stop_gfs
service httpd stop
umount /var/www
vgchange -aln
service clvmd stop
fence_tool leave
service fenced stop
cman_tool leave
service rgmanager stop
sleep 5
service cman stop

Never had, don't know why. Always figured it was because of the way I have to 
start my nodes. I wanted to add my shutdown script into the shutdown run 
levels so that it's automatic but am not sure how to add that in.

Do you mean I should just copy my shutdown script into that directory?

Well, here is my startup script for each node, maybe the answer lies in how I 
start them?

depmod -a
modprobe dm-mod
modprobe gfs
modprobe lock_dlm

service rgmanager start
ccsd
cman_tool join -w
fence_tool join -w
clvmd
vgchange -aly
mount -t gfs /dev/VolGroup04/web /var/www/

cp -f /var/www/system/httpd.conf /etc/httpd/conf/.
cp -f /var/www/system/php.ini /etc/.
/etc/init.d/httpd start
