make sure the time on the nodes is in sync, apparently when a node has
too much offset, you won't see rgmanager (even though the process is
running).
this happened today and setting the time fixed it for me. afaicr there
was no sign of this in the logs though.

If rgmanager doesn't show, check out the logs something may have gone wrong.

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 start
the VM, I don't know what causes it
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:
Service Name Owner (Last)
State
------- ---- ----- ------
-----
vm:guest1 (none)
stopped
But I can see the vm from xm li.
This is what I can see from the log:

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)

Ok. Please see below. my vm is running on all nodes though clustat

I am using cluster suite for HA of xen virtual machines. Now I am

This is usually done bei clurgmgrd (which is part of the rgmanager
package). To me, this sounds like a configuration problem. Maybe,
you can post your cluster.conf?
