Hi,

There is the ocf:heartbeat:Delay resource agent, which on one hand is
documented as a test resource, but on the other hand should do what you
need:

primitive solr ...
primitive two-minute-delay ocf:heartbeat:Delay \
  params startdelay=120 meta target-role=Started \
  op start timeout=180
group solr-then-wait solr two-minute-delay

Now the group acts basically like the solr resource, except for the
two-minute delay after starting solr before the group itself is
considered started.

Cheers,
Kristoffer
