Re: [ClusterLabs] I want to have some resource monitored and based on that make an acton. Is it possible?

Hi! Sorry for top-posting, but if you have NTP-synced your nodes, CLOCK_MONOTONIC will not have much advantage over CLOCK_REALTIME as the clocks will be rather the same, and they won't "jump". IMHO the latter is the main reason for using CLOCK_MONOTONIC (if the admin decides to adjust the
