Hi,
i remember that digimer often campaigns for a fence delay in a 2-node cluster.
E.g. here: http://oss.clusterlabs.org/pipermail/pacemaker/2013-July/019228.html
In my eyes it makes sense, so i try to establish that. I have two HP servers,
each with an ILO card.
I have to use the stonith:external/ipmi agent, the stonith:external/riloe
refused to work.
But i don't have a delay parameter there.
crm ra info stonith:external/ipmi:
Hi,
There is another ipmi fence agent - fence_ipmilan (part of fence-agents
package). It has 'delay' parameter.
...
pcmk_delay_max (time, [0s]): Enable random delay for stonith actions and
specify the maximum of random delay
This prevents double fencing when using slow devices such as sbd.
Use this to enable random delay for stonith actions and specify the maximum
of random delay.
...
This is the only delay parameter i can use. But a random delay does not seem to
be a reliable solution.
The stonith:ipmilan agent also provides just a random delay. Same with the
riloe agent.
How did anyone solve this problem ?
Or do i have to edit the RA (I will get practice in that :-))?
Bernd
