[one-users] Opennebula node (CentOS, Xen host) saying Error executing collectd-client.rb when creating a host.

Fri Aug 8 02:22:33 PDT 2014

Hi Chris,

I hope you managed find an explanation for this, otherwise I would go about
by:

* Edit /var/lib/one/datastores/im/run_probes
* Duplicate line 34 and insert an echo in the first one, so you know what's
going on
* This will probably identify a script that's failing
* Try to run it individually

This is probably a configuration problem..

hope this helps

cheers,
Jaime
