[Linux-HA] R1 to R2 testing: cib.xml & ldirectord questions for 2 node cluster

[Peter Farrell]

Hi Andreas - thanks for the tip.

RE: "OCF compliant resource agent for ldirectord"

Does that mean - use a definition other than "IPaddr" in the XML or
does that mean use the mythical wrapper script for ldirectord?

I found what was listed as an  "example script" written by yourself on
a mailing list - I'll paste it in below and you can tell me if it's
what I need.

I have seen several back and forth messages touching on this subject
in the last few months - but never anything concrete. Is this now
available in the source?
Earlier I looked up the fix in Bugzilla for Linux-HA (#105) and it
seemed dead to me.

-thanks again.

#
#       ldirectord OCF RA. Wrapper around /usr/sbin/ldirectord to
#       be OCF RA compliant and therefore to get the possibility
#   to monitor ldirectord by HAv2.
#   Tested on SuSE Linux Enterprise Server 10. Probably you
#   have to adjust the variables LDIRECTORD and the path to
#   /usr/lib/heartbeat/ocf-shellfuncs.
#
#   Should conform to the specification found at
#    http://www.linux-ha.org/OCFResourceAgent
#   and
#   http://www.opencf.org/cgi-bin/viewcvs.cgi/specs/ra/resource-agent-api.txt?rev=HEAD
#
#   ToDo: Add parameter to start several instances of ldirectord
#   with different config files.
