Re: [Linux-cluster] BladeCenter Fencing errors




I enabled telnet on the MM, now I am getting these messsages;

Jan 17 14:00:24 node1 fenced[3229]: fence "node2" failed
Jan 17 14:00:29 node1 fenced[3229]: fencing node "node2"
Jan 17 14:00:40 node1 fenced[3229]: agent "fence_bladecenter" reports: pattern match timed-out at /sbin/fence_bladecenter line 189

Jan 17 14:00:40 node1 fenced[3229]: fence "node2" failed
Jan 17 14:00:45 node1 fenced[3229]: fencing node "node2"
Jan 17 14:00:56 node1 fenced[3229]: agent "fence_bladecenter" reports: pattern match timed-out at /sbin/fence_bladecenter line 189

Jan 17 14:00:56 node1 fenced[3229]: fence "node2" failed
Jan 17 14:01:01 node1 fenced[3229]: fencing node "node2"
Jan 17 14:01:12 node1 fenced[3229]: agent "fence_bladecenter" reports: pattern match timed-out at /sbin/fence_bladecenter line 189

Line 189 looks like this;

 ($text, $match) = $t->waitfor("/system:blade\\[$bladenum\\]>/");


I am getting these on thesecond node;

Jan 17 14:03:24 mode2 fenced[3340]: fence "node1" failed
Jan 17 14:03:29 node2 fenced[3340]: fencing node "node1"
Jan 17 14:03:29 node2 fenced[3340]: fence "node1" failed
Jan 17 14:03:34 node2 fenced[3340]: fencing node "node1"
Jan 17 14:03:34 node2 fenced[3340]: fence "node1" failed

Unless you have modified the fence_bladecenter agent, it is unable to
make an ssh connection. It tries to use telnet.

There are open tickets against the agent right now, asking for ssh
support, and in fact I worked on this during the current development
cycle, but it will not make it into the next update release due to perl
module dependencies. After we are through the current crunch, the ssh
versions of 4 popular fence agents (including fence_bladecenter) will be
made available for testing if you are willing to install the necessary
perl modules yourself. In the meanwhile, we will be working to have the
necessary deps included in a future update.

Sorry this does not help you immediately.  If the network that you are
fencing on is secure, why not try telnet?
