Hi all,
I had a problem similar to Paras's one today: yum updated the following
rpms last week and today (I had to restart the cluster) the cluster was
not able to start vm: services.
Oct 02 05:31:05 Updated: openais-0.80.6-8.el5.x86_64
Oct 02 05:31:07 Updated: cman-2.0.115-1.el5.x86_64
Oct 02 05:31:10 Updated: rgmanager-2.0.52-1.el5.x86_64
Oct 03 04:03:12 Updated: xen-libs-3.0.3-94.el5_4.1.x86_64
Oct 03 04:03:12 Updated: xen-libs-3.0.3-94.el5_4.1.i386
Oct 03 04:03:16 Updated: xen-3.0.3-94.el5_4.1.x86_64
So, after checked the vm.sh script, I add the declaration use_virsh="0"
in the VM definition in the cluster.conf (as suggested by Brem, thanks!)
and everything is now working again.
BTW I didn't understand if the problem was caused by the new XEN version
or the new openais one, thus I disabled automatic updates for both.
I hope I'll not have any other bad surprise...
Thank you,
cheers,
Daniela

Hi Paras,
Your cluster.conf file seems correct. If it is not a ntp issue, I
don't see anything except a bug that causes this, or some prerequisite
that is not respected.
May be you could post the versions (os, kernel, packages etc...) you
are using, someone may have hit the same issue with your versions.

All of the nodes are synced with ntp server. So this is not the case with me.
Thanks

make sure the time on the nodes is in sync, apparently when a node has too

this happened today and setting the time fixed it for me. afaicr there was
no sign of this in the logs though.

Paras,
Another thing, it would have been more interesting to have a start
DEBUG not a stop.
That's why I was asking you to first stop the vm manually on all
your
nodes, stop eventually rgmanager on all the nodes to reset the
potential wrong states you may have, restart rgmanager.
If your VM is configured to autostart, this will make it start.
It should normally fail (as it does now). Send out your newly
created
DEBUG file.
2009/9/29 brem belguebli <brem.belguebli@xxxxxxxxx>:
Hi Paras,
I don't know the xen/cluster combination well, but if I do
remember
well, I think I've read somewhere that when using xen you have to
declare the use_virsh=0 key in the VM definition in the
cluster.conf.
This would make rgmanager use xm commands instead of virsh
The DEBUG output shows clearly that you are using virsh to manage
your
VM instead of xm commands.
Check out the RH docs about virtualization
I'm not a 100% sure about that, I may be completely wrong.
Brem
2009/9/28 Paras pradhan <pradhanparas@xxxxxxxxx>:
The only thing I noticed is the message after stopping the vm
using xm
in all nodes and starting using clusvcadm is
"Virtual machine guest1 is blocked"
The whole DEBUG file is attached.
Thanks
Paras.

There's a problem with the script that is called by rgmanager to

May be you should try something like :
1) stop the VM on all nodes with xm commands
2) edit the /usr/share/cluster/vm.sh script and add the
following
lines (after the #!/bin/bash ):
exec >/tmp/DEBUG 2>&1
set -x
3) start the VM with clusvcadm -e vm:guest1
It should fail as it did before.
edit the the /tmp/DEBUG file and you will be able to see where
it
fails (it may generate a lot of debug)
4) remove the debug lines from /usr/share/cluster/vm.sh
Post the DEBUG file if you're not able to see where it fails.

No I am not manually starting not using automatic init scripts.
I started the vm using: clusvcadm -e vm:guest1
I have just stopped using clusvcadm -s vm:guest1. For few
seconds it
says guest1 started . But after a while I can see the guest1 on
all
three nodes.
clustat says:

But I can see the vm from xm li.

When clustered, you should never be starting services
(manually or
thru automatic init script) out of cluster control
The thing would be to stop your vm on all the nodes with the
adequate
xm command (not using xen myself) and try to start it with
clusvcadm.
Then see if it is started on all nodes (send clustat output)
2009/9/25 Paras pradhan <pradhanparas@xxxxxxxxx>:
Ok. Please see below. my vm is running on all nodes though

This is usually done bei clurgmgrd (which is part of the

problem. Maybe,
you can post your cluster.conf?
