Hi,

I have 2 filers, 740 running 6.1.1R2 and 840 running 6.2R1.

I have the same timed setup on both machines:

timed.enable on timed.log on timed.max_skew 30m timed.min_skew 50 timed.proto ntp timed.sched hourly timed.servers ntphost1

Here's how the messages look for 740 filer:

Time reported by time server ntphost1 is Fri Apr 12 13:10:54 GMT 2002 (skew +0.088 secs). Time reported by time server ntphost1 is Fri Apr 12 14:08:34 GMT 2002 (skew +0.055 secs). Time reported by time server ntphost1 is Fri Apr 12 14:57:16 GMT 2002 (skew +0.129 secs). Time reported by time server ntphost1 is Fri Apr 12 17:11:09 GMT 2002 (skew +0.051 secs). Time reported by time server ntphost1 is Fri Apr 12 18:01:03 GMT 2002 (skew +0.058 secs). Time reported by time server ntphost1 is Fri Apr 12 19:01:11 GMT 2002 (skew +0.116 secs). Time reported by time server ntphost1 is Fri Apr 12 19:55:54 GMT 2002 (skew +0.080 secs). Time reported by time server ntphost1 is Fri Apr 12 20:06:43 GMT 2002 (skew +0.054 secs). Time reported by time server ntphost1 is Fri Apr 12 20:37:57 GMT 2002 (skew +0.098 secs). Time reported by time server ntphost1 is Fri Apr 12 21:05:39 GMT 2002 (skew +0.102 secs).

The skew is always positive and always small ( 0.1 secs or less ).

Now here're the messages for 840 filer:

Time reported by time server ntphost1 is Fri Apr 12 12:05:10 GMT 2002 (skew -0.177 secs). Time reported by time server ntphost1 is Fri Apr 12 13:05:32 GMT 2002 (skew -0.221 secs). Time reported by time server ntphost1 is Fri Apr 12 13:52:17 GMT 2002 (skew +0.238 secs). Time reported by time server ntphost1 is Fri Apr 12 14:03:44 GMT 2002 (skew -0.065 secs). Time reported by time server ntphost1 is Fri Apr 12 16:08:06 GMT 2002 (skew -0.101 secs). Time reported by time server ntphost1 is Fri Apr 12 17:00:57 GMT 2002 (skew -0.102 secs). Time reported by time server ntphost1 is Fri Apr 12 18:06:15 GMT 2002 (skew -0.199 secs). Time reported by time server ntphost1 is Fri Apr 12 18:53:44 GMT 2002 (skew +0.185 secs). Time reported by time server ntphost1 is Fri Apr 12 19:08:31 GMT 2002 (skew -0.243 secs). Time reported by time server ntphost1 is Fri Apr 12 20:01:58 GMT 2002 (skew -0.140 secs).

The skew's sign jumps back and forth, and the absolute value is over 0.2 secs ( becomes as high as 0.3 secs, which prompts make utility on clients to complain ).

What can be wrong with the clock on 840 filer? I suppose I can change timed.sched to sync more frequently, but I am just curious about the nature of the issue.

Thanks
