ibmrsa-telnet STONITH Not Working

Hey all.

I'm trying to add a couple of STONITH devices to my CIB, both
ibmrsa-telnet and they won't start with the following error logged:

stonithd: [3662]: WARN: start STONITH-1 failed, because its hostlist is
empty

The STONITH device doesn't accept the hostlist parameter:

OGG-MAIL-02:~ # stonith -t external/ibmrsa-telnet -n

nodename ip_address username password

I've tried it with the param anyway and it makes no difference.

I've found this patch
http://www.gossamer-threads.com/lists/linuxha/dev/51584?do=post_view_thr
eaded requires hostlist. Has the patch broken ibmrsa-telnet STONITH?

Thanks

Darren

Re: ibmrsa-telnet STONITH Not Working [In reply to]

The ibmrsa plugin requires mpcli to be installed and the ibmrsa-telnet
plugin doesn't work with newer RSA boards. It seems the hostlist error
was a dead herring leading me up the garden path.

I've altered the ibmrsa-telnet plugin a little to get it working with
the new format of the CLI (username : changed to login: > changed to
so if it's useful I've attached my changed version.

Darn, why did they have to change the text, as if "login" were so
much better than "username".

The only reasonable way would be to check the RSA release and
then to wait for the correct string. But first we have to figure
out when the change took place, that may be close to impossible.
I doubt that such information is in the release notes ;->

Looking at the Telnet documentation, there is another method
which waits for a set of regular expressions:

Telnet.expect(list...)

Perhaps we could modify the plugin to use that instead of
read_until(). I don't have an RSA board available though. Could
you try this out?

BTW, you also increased timeouts. Was that while you were testing
or is it really needed? At any rate, it's better to go with
longer timeouts.

Cheers,

Dejan

I could certainly try this, right about now is the perfect time to do it
too.

The prompts take quite a long time to appear, certainly longer than the
original timeouts. I think 20s should be long enough to allow for the
prompt but to time out in a reasonable time if something is wrong. I'll
have a look and see what I can do. Alternatively perhaps there can be a
ibmrsa-telnet1 and ibmrsa-telnet2 to allow for both revisions?

I'd like to avoid that if at all possible, it will be source of
endless confusion and a maintenance problem. As far as timeouts
go, it's OK if we adopt the longer ones. If a fence action
times out, that happens only once and ends in error. It may take
a bit longer for that to happen, but it should be fairly seldom
on a well administered cluster.

Sorry for top-posting. Afflicted with Outlook.

Here is the STONITH agent. I've tested it on both old and new and it
seems fine.
