# This is a one-shot OCF resource agent with the next properties:
|
|
#
|
|
# * It wraps the init.d script to make an OCF-RA
|
|
# * It maps the start, stop, monitor to start, stop , status, and provides
|
|
# the specific OCF ones.
|
|
# * It cleans unused resources during start (system or agents startup)
|
|
# * It cleans everything on stop (agents migration to other hosts)
|
|
# * Once started, it will respond with status = OK
|
|
# * Once stopped, it will respond with status = DEAD
