But there are basically 3 reasons why pcmk_delay_base should be preferred:
- can be used with all ways of fencing not just RHCS-style fence-agents - if the fencing-infrastructure knows that no sub-process - running the fence-agent - has been started yet it is easier to handle a termination - if combined with a random delay you get a delay that varies between pcmk_delay_base and pcmk_delay_max which is more comprehensible than with using the delay in fencing library where the effective delay would derive to something between {delay define via fencing library} and pcmk_delay_max + {delay defined via fencing library} Regards, Klaus > > For some additional info: > - Table 13.1.
