Hello,
As fence_idrac has never worked for us, and as fence_ipmilan has worked
nicely since years, we are using fence_ipmilan with the lanplus=1
option
and we're happy with it.
We upgraded to 4.3.0.4 and we're witnessing that we cannot fence our
hosts anymore :
2019-02-18 09:42:08,678+01 ERROR
[org.ovirt.engine.core.bll.pm
<http://org.ovirt.engine.core.bll.pm>.FenceProxyLocator] (default
task-11)
[2f78ed99-6703-4d92-b7cb-948c2d24b623] Can not run fence action on host
'xxxxx', no suitable proxy host was found.
This is not related fence_ipmi issue below. Engine, is order to be able
to execute fencing operation, needs at least one other hosts in Up
status, which is used as a proxy host to perform fencing operation. So
do you have at least one host in Up status in the same
cluster/datacenter as the host you want to run fencing operation on?
Yes.
If so, then please enable debug information to find out why we cannot
find any host acting as fence proxy:
1. Please download log-control.sh script from
https://github.com/oVirt/ovirt-engine/tree/master/contrib#log-control-sh
and save on engine machine
2. Please execute following on engine machine
log-control.sh org.ovirt.engine.core.bll.pm
<http://org.ovirt.engine.core.bll.pm> DEBUG
3. Go to the problematic host, click Edit, go to Power Management tab,
click on the existing fence agent and click on Test button
4. Take a look at engine.log, there should be logged information, why we
were not able to find out fence proxy
I followed the instructions above, but I feel this is not the best debug
path. I learned nothing new.
The fence proxy is not missing. It is known and found, and it is trying
to do its job, as written below :
and on the SPM :
fence_ipmilan: Failed: Unable to obtain correct plug status or plug is
not available
Could you please provide debug output of below command?
ipmitool -vv -I lanplus -H <IPMI_INTERFACE_IP> -p 623 -U <IPMI_USERNAME>
-P <IPMI_PASSWORD> -L ADMINISTRATOR chassis power status
See below a debug session.
I'm comparing two hosts, and one only is answering fence status queries.
I must add that before the upgrade to 4.3, both hosts were responding
correctly.

Above is the command which fence_ipmi is internally executing, and -vv
adds debugging output which can reveal issue with the plug status

Martin
I found the suggested workaround here :
https://access.redhat.com/solutions/3349841
but no combination of
- lanplus={0,1}
- -z
- ssl=={0,1}
lead to no solution.
The package version is the same as what's described in the KB :
fence-agents-rhevm-4.2.1-11.el7_6.7.x86_64
What should I test now?
Thank you.
