Hi there,

thanks for your reply.

This version is in the debian stable repositories, I’ve installed from there.

http://packages.debian.org/search?keywords=fence-agents

 

Next time I know better…

Kind regards

Hi there,

I’m trying to setup a cluster and had issues with ‘fence_ipmilan’ from the package fence-agents.

I’m running debian 7.1 with a 3.2.0-4-amd64 kernel.

‘fence_ipmilan –V’ gives ‘fence_ipmilan 3.1.5’

My Cluster nodes are running on Supermicro Motherboards with IPMI on-board. (To be exact: http://www.supermicro.nl/products/motherboard/Xeon/C202_C204/X9SCA-F.cfm )

I’ve experienced the following behavior:

 

fence_ipmilan -a xxx.xxx.xxx.xxx -l USER-p PASS -v -o off; echo $?

ipmilan: Power still on

More or less in the same moment when I got this message the machine went down. So all the commands were working, but not in the expected time.

( Using Supermicro Mainboards with IPMI onboard, http://www.supermicro.nl/products/motherboard/Xeon/C202_C204/X9SCA-F.cfm )

I’ve played around with available parameters and wasn’t able to fix this behavior.

So I went into the source code(fence-agents-3.1.5/fence/agents/ipmilan/ipmilan.c) and had a look at the ipmi_off function.

There was a fixed value of 2 seconds to sleep.

I modified this to use the same parameter like ipmi_on: ipmi-> i_power_wait instead of 2, so that I can modify this value and test if it has effect on my problem.

Now when I use the modified version of fence_ipmilan the output looks like:

 

./fence_ipmilan -a xxx.xxx.xxx.xxx -l USER -p PASS -T 10 -v -o off ; echo $?

Spawning: '/usr/bin/ipmitool -I lan -H 'xxx.xxx.xxx.xxx' -U 'USER' -P 'PASS' -v chassis power off'...

Spawning: '/usr/bin/ipmitool -I lan -H 'xxx.xxx.xxx.xxx' -U 'USER' -P 'PASS' -v chassis power status'...

Done

0

 

So I think this fixed my problem, and I think it might help other users experiencing the same issues.

Kind regards

 

Thanks for reporting, I'm quite suprised that you use such old version. This issue was fixed in 3.1.8 (26 Mar 2012)
