Host synchronization

The hosts will be charge to synchronize the time both with NTP and PTP with timemaster. It's configured during the network (see Network architecture section).

  • chrony synchronize the system clock with NTP on specified servers with (ntp_primary_server and ntp_secondary_server).
  • ptp4l synchronize the hardware clock (PHC) with PTP.
  • phc2sys synchronize clocks (hardware and system).

With PTP, the system will have a better precision. So, in the cluster, all hosts will be on the same time. It's important when hosts want to add resource in the shared storage.
