Re: Fence_ilo issue — Linux Clusters

Hi,

I am facing issues with the fence_ilo. We have sixteen nodes clusters. One of the node have
some issue and from other node tried to fence that node but, could not, the error is:

    node1 fenced[12698]: fencing node "node2-priv.xxx.xxx"
    node1 fenced[12698]: agent "fence_ilo" reports: Unable to connect/login to fencing device
    node1 fenced[12698]: fence "node2-priv.xxx.xxx" failed
    node1 openais[12590]: [TOTEM] entering GATHER state from 11.

The fencing node is out of the cluster now. but still from node1 it is trying to fence.

Here is the cluster config file..

<clusternodes>

<clusternode name="node1-priv.xxx.xxx" nodeid="1" votes="1">
                 <fence><method name="1">
                 <device name="ilo-node1r" action="">                  </fence>
</clusternode>

<clusternode name="node2-priv.xxx.xxx" nodeid="2" votes="1">
        <fence><method name="1">
        <device name="ilo-node2r" action="">         </fence>
</clusternode>

        <fencedevice agent="fence_ilo" hostname="node1r" login="Admin" name="ilo-node1r" passwd="xxxxxxxx"/>
        <fencedevice agent="fence_ilo" hostname="node3r" login="Admin" name="ilo-node3r" passwd="xxxxxxxx"/>
        <fencedevice agent="fence_ilo" hostname="node2r" login="Admin" name="ilo-node2r" passwd="xxxxxxxx"/>

I tried to login ILO of node2 with ssh , using the ILO user/passw as Admin/xxxxxxxx, it worked

Here the report:

[root@node1 tmp]# ssh Admin@node2r
Admin@node2r's password:
User:Admin logged-in to node2R.(xxx.xx.xx.xx)
iLO 2 Standard Blade Edition 2.01 at 11:16:29 Aug 04 2010
Server Name: node2
Server Power: On

</>hpiLO->

One more information : The dns entries of ILO has no reverse entry . only the ip in the dns.

I have tested the ilo fencing in the lab .. and it works fine...

Any advice will be appreciated , where to look, why the fence did not work.

Thanks again
