[ClusterLabs] error external/libvirt device not accessible

[Oscar Salvador]

Hi!

I have a problem with fencing.
I'm using fence-agents, and a configured a one that uses libvirt device.

Versions:

fence-agents                   4.0.18
corosync                        2.3.4
pacemaker                      1.1.12

Here is the configuration:

node 1053402612: server01
node 1053402613: server02
primitive IP-rsc_nginx IPaddr2 \
        params ip=xx.xx.xx.xx nic=eth0 cidr_netmask=xx.xx.xx.xx \
        meta migration-threshold=2 \
        op monitor interval=20 timeout=60 on-fail=restart
primitive Nginx-rsc nginx \
        meta migration-threshold=2 \
        op monitor interval=20 timeout=60 on-fail=restart
primitive p_fence_server01 stonith:external/libvirt \
        params hostlist=server01
hypervisor_uri="qemu+tcp://virtnode01/system" \
        op monitor interval=60
primitive p_fence_server02 stonith:external/libvirt \
        params hostlist=server02
hypervisor_uri="qemu+tcp://virtnode02/system" \
        op monitor interval=60
location l_fence_server01 p_fence_server01 -inf: server01
location l_fence_server02 p_fence_server02 -inf: server02
colocation lb-loc inf: IP-rsc_nginx Nginx-rsc
order lb-ord inf: IP-rsc_nginx Nginx-rsc
property cib-bootstrap-options: \
        stonith-enabled=true \
        no-quorum-policy=ignore \
        default-resource-stickiness=100 \
        dc-version=1.1.12-561c4cf \
        cluster-infrastructure=corosync


Whe I commit the conf, I can see the followning in the logs:

First:

*Jun 15 10:16:05 [27835] server02   stonithd:     info: cib_device_update:
      Device p_fence_server02 has been disabled on server02:
score=-INFINITY*

Since I specifed a location with:

"*location l_fence_server02 p_fence_server02 -inf: server02*"

Why it put an -INFINITY score? It is the default behaviour? As far as I
know, -INFINITY means "not run this resource on this node".

Then I receive:


*Jun 15 10:16:05 [27835] server02   stonithd:     info:
xml_patch_version_check:         Current num_updates is too high (8 > 7)*

*Jun 15 10:16:07 server02 stonith: [30410]: ERROR: external/libvirt device

*Jun 15 10:16:07 [27835] server02   stonithd:     info:

*Jun 15 10:16:09 [27835] server02   stonithd:     info:

*Jun 15 10:16:09 [27835] server02   stonithd:   notice: log_operation:

*Jun 15 10:16:09 [27835] server02   stonithd:  warning: log_operation:

*Jun 15 10:16:09 [27835] server02   stonithd:  warning: log_operation:
p_fence_server01:30434 [ failed:  1 ]*


One think it called my attention was:

"Performing: stonith -t external/libvirt -S"

If I execute this command, I receive:

*# stonith -t external/libvirt -S*
*Must specify either -p option, -F option, -E option, or name=value style
arguments*
*usage:*
* stonith [-svh] -L*
* stonith [-svh] -t stonith-device-type -n*
* stonith [-svh] -t stonith-device-type -m*
* stonith [-svh] -t stonith-device-type {-p stonith-device-parameters | -F
stonith-device-parameters-file | -E | name=value...} [-c count] -lS*
* stonith [-svh] -t stonith-device-type {-p stonith-device-parameters | -F
stonith-device-parameters-file | -E | name=value...} [-c count] -T
{reset|on|off} nodename*

*where:*
* -L list supported stonith device types*
* -l list hosts controlled by this stonith device*
* -S report stonith device status*
* -s silent*
* -v verbose*
* -n output the config names of stonith-device-parameters*
* -m display meta-data of the stonith device type*
* -h display detailed help message with stonith device description(s)*


Si, it seems that it is executed with some missing parameters.

Anyone has an idea?

Thank you very much in advance
Oscar
