Re: Installing packages on OKD 4 nodes

2020-10-28 Thread Joel Pearson 
Hi Benjamin,

Alas, Fedora CoreOS must differ here.

I did find this workaround for installing packages via ignition, if adding
linuxptp actually made it work for you, then this might help:
https://github.com/coreos/fedora-coreos-tracker/issues/307

I don't know how this would work with OS updates coming via the machine
config operator. Could be worth a try I guess?

Thanks,

Joel

Re: Installing packages on OKD 4 nodes

2020-10-28 Thread Benjamin Guillon 
Hi Joel, 

Well, no: /dev/ptp0 does not magically exists. Wouldn't that be too easy? :) 

As for a FCOS specific documentation regarding NTP/PTP I'm afraid I didn't find 
any.

Hi Benjamin, 
Those docs you’ve mentioned are for regular fedora not fedora coreos I believe 
which I’m pretty sure are very different. 

So I presume you have checked that /dev/ptp0 doesn’t already magically exist?

Hi Joel, 

Thanks for the reply :) 

I did give a try to the Openshift PTP operator and works well aside from the 
fact that I can't use it here since I'm not running on Baremetal. 

Our cluster indeed runs on our in-house Openstack platform. 

Usually we use the KVM PTP module with something like: 
refclock PHC /dev/ptp0 poll 2 
In the chrony.conf file. 
But that's for our usual CentOs based VMs, not FCOS :/ 

So now I'm just trying to reproduce that setup on FCOS. 
I found this Fedora documentation earlier about PTP 
https://docs.fedoraproject.org/en-US/fedora/rawhide/system-administrators-guide/servers/Configuring_PTP_Using_ptp4l/
 
Where they mention this linuxptp package, hence my questions. 

If I can't manage this, I'll resort to using standard NTP instead of PTP.

If you don't have access to that solution the crux of it is that the PTP 
operator is for baremetal nodes (so probably not you, as you mentioned 
OpenStack). 

The chrony config they mention is: 

$ cat << EOF | base64 -w0

Re: Installing packages on OKD 4 nodes

2020-10-28 Thread Joel Pearson 
Hi Benjamin,

Have you checked if you actually need it? At least enterprise openshift 4.x
already had ptp support in the kernel (without a module), as I bumped into
it earlier in the year for PTP Azure syncing, I opened a support ticket and
it turned out I just needed this in chrony.conf

refclock PHC /dev/ptp0 poll 3 dpoll -2 offset 0

So I think it'd be worth checking if you already have /dev/ptp0 available
before installing linuxptp.  I realise OKD uses Fedora Core OS instead of
RedHat Core OS, so the default kernel modules might be different.

Here are some docs for configuring chrony
,
I think you just need to switch the iburst line for the refclock one.

Otherwise, if the PTP support you need is more complicated than I needed on
Azure, you could potentially look at the specific PTP operator

in the OKD docs.

Hope this helps.

Thanks,

Joel
