[ovirt-users] Options not being passed fence_ipmilan, Ovirt3.5 on Centos 7.1 hosts

Tue Apr 21 17:16:18 UTC 2015

Hi All,

I have a bit of an issue with a new install of Ovirt 3.5 (our 3.4 cluster
is working fine) in a 4 node cluster.

When I test fencing (or cause a kernal panic triggering a fence) the
fencing fails. On investigation it appears that the fencing options are not
being passed to the fencing script (fence_ipmilan in this case):

Fence options under GUI(as entered in the gui): lanplus, ipport=623,
power_wait=4, privlvl=operator

from vdsm.log on the fence proxy node:

For verification I temporarily replaced /usr/sbin/fence_ipmilan with a
shell script that dumps the env plus any cli args passed into a log file:

-------------------------- Tue Apr 21 12:39:39 EDT 2015

I've found some old post from 2012 that describe the same problem. Has
anyone else run into this?

Any thought or suggestions would be appreciated.

Cheers,
Mike
