Contradictory doc on cron jobs for web cluster

Hi,

I think the doc has contradictory info on  whether a recent version of moodle can have a cron job in each node (asuming same app instance and one database) or only a cron job in one node:

For 2.7 cron job: NO

"If both your servers are web servers, and they jointly serve one Moodle instance (in some sort of a cluster), then only one server should run the Moodle cron job"

For 2.7 upgrading: Yes

"Clusters with multiple identical application nodes are supported, you can run cron on all of them"

If using a version prior 2.7, one app instance, one DB, can I config a cron job in at least two nodes (for High Availability)?


Thanks,

I suspect the upgrading document is correct and the other was simply not updated between versions. 

To be honest this change is news to me. What I can't tell you - but would be interested to know - is if there is an advantage in doing this. Up until now I have tended to recommend using a dedicated front end just for cron. I don't know if this changes things.
