===== Fix resource usage errors =====

There is an utility, implemented at CERN (https://github.com/cernops/nova-quota-sync), which is able to detect and fix errors in the resource usage.
It has been installed on cld-ctrl-01 in /usr/local/bin/nova-quota-sync

To just see the problem:

<code bash>
[root@cld-ctrl-01 ~]# python /usr/local/bin/nova-quota-sync --no_sync
