[Linuxptp-users] Failure to switch to NTP source from currently synced PTP source when PTP master fails using timemaster service

[प्रदीप क. भ. <par...@gm...>]

I am using the latest version 1.9.2 of linuxptp wherein , I am combining
the NTP as well as PTP sources using timemaster program in the client
machine running RHEL 7.1.
I am facing issues w.r.t the time source selection. I have 1 PTP source and
3 NTP sources. Whenever all 4 sources are present and working, the local
clock gets synchronized with the PTP master but as soon as I make the PTP
master offline, the timemaster service does not switch to any of NTP
sources and always indicates that it is synced to PTP, which is false . I
have tested this for continuous 24 hours of operation. However , when I
restart the timemaster service, it gets synchronized with the best NTP
server. So every time, I have to restart the timemaster service when the
PTP master fails.
Looking forward for a solution and possible configuration change if
required.
