I have the following problem in my cluster (built from two Alpha server, node A and node B):
- NTP is enabled on both nodes
- both nodes should get the time from our timeserver.
- node B gets the time, node A not
I now have a time difference of about 5 minutes between node A and node B.
What dis I wrong, or what can I do to get rid of the problem ???
Any hint is greatly appreciated.
Regards,
Karl-Heinz

Re: Time synchronization in a cluster
$ @sys$manager:tcpip$define_commands
and then
$ ntpq -pn
and
$ ntptrace -n
Then check for any differences.

Re: Time synchronization in a cluster
the TCPIP$NTP.CONF files are identical on both systems (see attachment)
The result from the mentioned commands are:
$ NODE_B>ntpq -pn
remote refid st t when poll reach delay offset jitter
==============================================================================
*10.20.96.171 .hopf. 1 u 669 1024 377 10.697 -2.318 0.618
$ NODE_B>ntptrace -n
127.0.0.1: stratum 2, offset 0.000000, synch distance 0.03075
10.20.96.171: stratum 1, offset -0.000395, synch distance 0.00224, refid 'hopf'
$ NODE_A>ntpq -pn
No association ID's returned
$ NODE_A>ntptrace -n
127.0.0.1: stratum 16, offset -0.000488, synch distance 1.19597
0.0.0.0: *Not Synchronized*

Re: Time synchronization in a cluster
no firewalls, traceroute works :
$ NODE_A>traceroute -n 10.20.96.171
traceroute to 10.20.96.171 (10.20.96.171): 1-30 hops, 38 byte packets

2 193.26.200.1 9.76 ms 9.76 ms 9.76 ms
3 193.26.203.10 10.7 ms 9.76 ms 10.7 ms
4 10.1.200.250 10.7 ms 11.7 ms 10.7 ms
5 10.20.96.171 11.7 ms 10.7 ms 12.6 ms
