Time sync problem

Hello,

Thanks in advance for any time spent or help offered.

I administer a Netware 6.0 SP5 two node native SCSI based cluster that sits
on a large university LAN that we share with other many servers and
workstations. We also have one replica server in an office still on the LAN
but two hops away from the server cluster.

The server that is typically secondary is set up as a single source that
gets its time from an NIST timeserver. It is always in sync. The replica
server is always in sync. But for the last few days the primary server in
the cluster has been loosing and regaining its time sync every minute (see
health.log below) It has been running for 103 days. We haven't seen any
other problem.

I installed the Netware and Java DST updates Monday, but this problem had
been going on before that.

Here is the last 5 minutes from the health log. (The log reached its max
size and started over Tuesday.)

Re: Time sync problem

Can we see the timesync.cfg files from both servers; identify any IP
addresses mention in them. Thanks.

Over the weekend, I was able to restart the sever and the problem seems to
be gone. The cluster resources migrated to our older and slower server, but
it seems to be doing fine. No time sync errors...at least not yet.

Below are the contents of the three timesync.cfg files.

timesync.cfg (from 3 servers)

***Server in cluster set up as single reference

# TimeSync.Cfg is now updated automatically,
# when changes are made on the System Console

# TIMESYNC Configuration Parameters

Configured Sources = ON
DEBUG = 7
Polling Count = 3
Polling Interval = 600
Service Advertising = ON
Synchronization Radius = 2000
Type = SINGLE
NTP Client Port = 0

# TIMESYNC Configured time source list

TIME SOURCE = 208.184.49.9:123 <NIST time server>




***Server in cluster that is

# TimeSync.Cfg is now updated automatically,
# when changes are made on the System Console

# TIMESYNC Configuration Parameters

Configured Sources = ON
DEBUG = 7
Polling Count = 6
Polling Interval = 600
Service Advertising = ON
Synchronization Radius = 2000
Type = SECONDARY
NTP Client Port = 0

# TIMESYNC Configured time source list

TIME SOURCE = 128.59.xxx.xxx:123 <address of our single reference>



***Replica server

# TimeSync.Cfg is now updated automatically,
# when changes are made on the System Console

# TIMESYNC Configuration Parameters

Configured Sources = ON
DEBUG = 7
Polling Count = 6
Polling Interval = 600
Service Advertising = ON
Synchronization Radius = 2000
Type = SECONDARY
NTP Client Port = 0

# TIMESYNC Configured time source list

TIME SOURCE = 128.59.xxx.xxx:123 <address of our single reference>

Re: Time sync problem

That all looks perfectly fine. Sorry, I have no idea what caused your
problem. You might consider making the server outside the cluster the
SINGLE, as presumably it is less busy and less liable to go down.

Re: Time sync problem

Thank you. I'll try that if it goes out of sync again.
