I use virt-install to create virtual machines. Is there a way to debug why clusvcadm -e vm:guest1 is failing? vm.sh seems to use virsh and my cluster.conf has use_virsh=0
Thanks
Paras.

Well no i don't want to use virsh. But as we are debugging with virsh now i found a strange issue.I exported an xml file and imported to all nodes . Ran
---name="guest1" path="/vms_c"
export OCF_RESKEY_name="guest1" ; OCF_RESKEY_path="/vms_c"
set -x
/usr/share/cluster/vm.sh start
set +x--vm starts now. BUT from a cluster service : cluvscam -e vm:guest1 , same error.
So if i populate all my domains' config files to all my cluser nodes and make use_virsh=1, then the issue is resolved. But this is a lot of work for those who have hundreds of vm.vm.start uses virsh . Is there a way to tell him not use virsh?ThanksParas.On Thu, Nov 21, 2013 at 5:19 PM, emmanuel segura <emi2fast@xxxxxxxxx> wrote:toif you are using virsh for manage your vms, change this in your cluster.conffrom

2013/11/22 Paras pradhan <pradhanparas@xxxxxxxxx>I think i found the problem.virsh list --all does not show my vm . This is because it was created on another node. and another node has it. Now I want to start the service on a different node in which it was not created or where virsh list --all does not have an entry. Is it possible to create this entry using a xen config file?Looks like this is now a Xen issue rather than a linux-cluster issue . :)Paras.On Thu, Nov 21, 2013 at 4:58 PM, emmanuel segura <emi2fast@xxxxxxxxx> wrote:

Well it is guest1. Isn't it?.<vm autostart="1" domain="myfd1" exclusive="0" max_restarts="0" name="guest1" path="/vms_c" recovery="restart" restart_expire_time="0" use_virsh="0"/>
It is a vm service if it matters.-Paras.On Thu, Nov 21, 2013 at 4:22 PM, emmanuel segura <emi2fast@xxxxxxxxx> wrote:

--Hi,My failover domain looks like this:<failoverdomain name="myfd1" nofailback="1" ordered="1" restricted="0"><failoverdomainnode name="vtst1" priority="1"/><failoverdomainnode name="vtst3" priority="2"/><failoverdomainnode name="vtst2" priority="3"/></failoverdomain>I have vm service that uses this failover domain. If my node vtst1 is offline, the service doesnot start on vtst3 which is 2nd in the priority.I tried to start it with: clusvcadm -e vm:guest1 and even with -F and -m option.All i see is this error:Nov 21 15:40:29 vtst3 clurgmgrd[13911]: <notice> start on vm "guest1" returned 1 (generic error)Nov 21 15:40:29 vtst3 clurgmgrd[13911]: <warning> #68: Failed to start vm:guest1; return value: 1Nov 21 15:40:29 vtst3 clurgmgrd[13911]: <notice> Stopping service vm:guest1Nov 21 15:40:35 vtst3 clurgmgrd[13911]: <notice> Service vm:guest1 is recoveringNov 21 15:40:35 vtst3 clurgmgrd[13911]: <warning> #71: Relocating failed service vm:guest1Nov 21 15:40:35 vtst3 clurgmgrd[13911]: <notice> Service vm:guest1 is stoppedHow do I debug?Thanks!Paras.
