Well, we spent a bit of time looking at this before the release went
out, and thought we had fixed it. In fact, is is fixed on SUSE Linux,
but obviously not really fixed :-(.

R2 external STONITH handling is much more sophisticated, and much
better. But, there is no separate external device, but it supports
external devices.

Could you take out a bugzilla for this?

The 2cib converter translated this v1 line:
stonith_host * external foo /etc/ha.d/wti.pl

into:

---<SNIP>---
<primitive class="stonith" id="stonith_6" provider="heartbeat"
type="external">
<operations>
<op id="stonith_6_mon" interval="5s" name="monitor" prereq="nothing"
timeout="20s"/>
<op id="stonith_6_start" name="start" prereq="nothing" timeout="20s"/>
</operations>
<instance_attributes id="stonith_6_inst_attr">
<attributes>
<nvpair id="stonith_6_attr_2" name="ibmrsa" value="foo"/>
<nvpair id="stonith_6_attr_3" name="riloe" value="/etc/ha.d/wti.pl"/>
</attributes>
</instance_attributes>
</primitive>
---<SNIP>---

This looks futile, what would be the R2 way to use a script to handle
the stonith?

A very silly output ;-) It should have reported error (I'll fix
that), because your cf line should have been sth like:

stonith_host * external/foo /etc/ha.d/wti.pl

It's just a resource of the stonith class. Set attributes which
the stonith agent supports (get a list from "stonith -n -t
agent"). There is one example here

The external API is very different for R2, so your script will have to
change.

But, for this particular mistake, I blame Dejan ;-)

Thanks, I'll have a look at
