[chrony-users] peers and prefer option

[cfanygapa <cfanygapa@xxxxxxx>]

Dear Group,

I have 4 Chrony local servers which are peers to each other. All 4 are 
synced to separate sets of external NTP Stratum-1 servers. Then internal 
clients are using all 4 internal servers as their sources.
The question is... is it worth to mark external Stratum-1 servers with 
"prefer" option?
I am asking, because I have noticed that one of my 4 servers seems to 
obtain "visibly better quality" time, so as a result, other 3 peers 
start to synchronize to it (marking with *) instead of synchronizing to 
one of their many avaialable Stratum-1 in the web. It causes an expected 
but funny situation that one of my 4 servers is leading Stratum 2 and 
others treating it as source, become Stratum 3.
So thought I'll mark all external Stratum-1 servers with "prefer" option 
which will not allow situation described above, until an emergency 
situation when all of external Statum-1s for particular server will be 
unreachable, then selecting the peer could happen.
Do you think such configuration makes sense or better to leave Chrony to 
do its job as at the end it is all about "averaging" measurements and my 
idea won't change much anyway?

Thanks in advance
Tom
