Re: [Linux-cluster] manual fencing -- issues



My understanding is that fence device selection is done by ordering, but I could be wrong.

Hello,

I know that manual fencing is not supported.  However, I don't have
anything else with the hardware I am testing at this time.  When (if)
we go live with this, I'll be using Dell DRACs to handle the fencing.
At any rate, I am trying manual fencing to test proof of concept.  I
am using RHEL5.1 with Conga to configure it.  My config is at the
bottom of this email.   Shouldn't there be a nodename paramater in
this block:
                       <fence>
                               <method name="1">
                                       <device name="fence00"
nodename="dss01.foobar.local"/>
                               </method>
                       </fence>

??  If so, why isn't Conga configuring this correctly?  If not, why am
I getting this error during a crash of the node with the service on
it:
Jan 29 10:56:08 dss00 fenced[2965]: agent "fence_manual" reports:
failed: fence_manual no node name
Jan 29 10:56:08 dss00 fenced[2965]: fence "dss01.foobar.local" failed

Thanks for any ideas.
