Andreas,
Here is something interesting for you. While attempting to define the
config. via "crm configure" I received and error stating the parameter was
invalid:
primitive ec2-fencing stonith:fence_ec2 \
params ec2-home="<ec2_location>" pcmk_host_check="static-list"
pcmk_host_list="node1 node2 node3" \
op monitor interval="600s" timeout="300s" \
op start start-delay="30s" interval="0"
ERROR: ec2-fencing: parameter ec2-home does not exist
I then issued a request for the metadata via stonith_admin:
# stonith_admin --metadata --agent=fence_ec2
... and received the following. I see the "action" parameter but none of
the others?! fence_ec2 is located in /usr/sbin, owned by root and 755 like
the other agents. All other agents return XML with more/several
parameters. Shouldn't we be seeing all the parameters in the XML output?
I'm thinking "port", "ec2-home", "tag", etc.
<?xml version="1.0"?>
