[Pacemaker] Cannot clean history

[Alexandre]

Hi,

I have a pacemaker / corosync / cman cluster running on redhat 6.6.
Although cluster is working as expected, I have some trace of old failures
(several monthes ago) I can't gert rid of.
Basically I have set cluster-recheck-interval="300" and
failure-timeout="600" (in rsc_defaults) as shown bellow:

property $id="cib-bootstrap-options" \
dc-version="1.1.10-14.el6-368c726" \
cluster-infrastructure="cman" \
expected-quorum-votes="2" \
no-quorum-policy="ignore" \
stonith-enabled="false" \
last-lrm-refresh="1429702408" \
maintenance-mode="false" \
cluster-recheck-interval="300"
rsc_defaults $id="rsc-options" \
failure-timeout="600"

So I would expect old failure to be purged from the cib long ago, but
actually I have the following when issuing crm_mon -frA1.

Migration summary:

I have tried to crm_failcount -D the resources also tried cleanup... but
it's still there!
How can I get reid of those record (so my monitoring tools stop
complaining) .

Regards.
