By default, a start failure is considered permanent, resulting in a
failcount of 1000000, meaning the resource cannot run on that node again.

You'll have to reset the failcount for that resource on the particular
node to make it run again.

You can change the behaviour by setting "start-failure-is-fatal" (in
crm_config) to false, which would just try starting the resource over
and over until it reaches its migration-threshold. A start failure then
only means failcount+1.
