Hi,
I want to use snmp_subagent on Heartbeat 2.0.6 without
using CRM v2-style configuration. I don't like the complexity
of CRM daemons and CIB XML configuration so I have disabled
CRM support with configure options but CRM binaries still
compiled ??? --disabled-crm or --enable-crm=no same effect..
I want to use v1-style configuration but use hbagent anyway.
After some research I have found a post from Horms with
a patch from Takahiro Kurosawa. I have ported this patch
to Heartbeat 2.0.6 stable version.
http://lists.community.tummy.com/pipermail/linux-ha-dev/2005-August/011441.html
Could you include the patch in attachment in your next release or
put in the contrib directory of your archive ?
hbagent have some trouble accessing
"/opt/heartbeat/lib/hearbeat/ResourceManager"
Check grep -rn 'HA_LIBDIR"/heartbeat' *; grep -rn 'HALIB "/heartbeat' *;
grep -rn 'ResourceManager ' *
# So what is the right path ?
sprintf(getcmd, HALIB "/ResourceManager status %s", resource);
sprintf(getcmd, HALIB "/heartbeat/ResourceManager status %s", resource);
sprintf(getcmd, HA_LIBDIR "/heartbeat/ResourceManager status %s", resource);
