My issue is that when I restart chrony, delete the ntp, and re-add the ntp but with the correct offset, it only then synchronizes to my refclock PPS half the time. I want it to consistently sync to the PPS after.
When it fails to sync to the PPS afterwards, the PPS' status is stuck as '?,' or itll say its synced but the LastRX never resets/resets after a couple minutes despite ppswatch and ppstest showing/recognizing a PPS every second (with it being at poll 3). So that was my aforementioned issue I noticed. When I try "chronyc selectdata" or "chronyc selectdata -a" I get a unrecognized command return. My issue with the local directive is that from my understanding reading it, it makes chronyd to be an ntp server when I want it to be synced to an external ntp and then a PPS. (I am trying to sync multiple devices, so the local command would appear to make everything unsynchronized). -----Original Message----- From: Miroslav Lichvar <mlich...@redhat.com> Sent: Monday, December 7, 2020 8:14 AM To: chrony-users@chrony.tuxfamily.org Subject: Re: [chrony-users] Chronyc Call to Add Refclock On Mon, Dec 07, 2020 at 01:03:38PM +0000, Chang, Benjamin wrote: > > I've tried restarting chrony, then delete the ntp, reading the ntp with the > > offset, and then makestep.

You are getting falsetickers when both the NTP source and PPS refclocks are enabled? Do you have the "local" directive in chrony.conf? The selectdata output might help, or the statistics log. -- Miroslav Lichvar -- To unsubscribe email chrony-users-requ...@chrony.tuxfamily.org with "unsubscribe" in the subject.
