NTP time sync issue - done everything to resolve but no go....

curious_V — Wed, 04 Jun 2025 21:02:57 GMT

I am running NetApp Release 8.1.4P9 7-Mode and facing issue with the NTp Sync issue.

The two filers NA001 and NA002 are in HA pair

NA001 time is behind the NTP time by 16 mins while NA002 is ahead of NTP by approx 30 seconds.

The option time is as below

na001> options time
timed.enable on (same value in local+partner recommended)
timed.log on (same value in local+partner recommended)
timed.max_skew 30m (same value in local+partner recommended)
timed.min_skew 0 (same value in local+partner recommended)
timed.proto ntp (same value in local+partner recommended)
timed.sched 1h (same value in local+partner recommended)
timed.servers 10.18.150.31,10.18.152.31 (same value in local+partner recommended)
timed.window 0m (same value in local+partner recommended)

na002> options time
timed.enable                 on         (same value in local+partner recommended)
timed.log                    on         (same value in local+partner recommended)
timed.max_skew               30m        (same value in local+partner recommended)
timed.min_skew               0          (same value in local+partner recommended)
timed.proto                  ntp        (same value in local+partner recommended)
timed.sched                  1h         (same value in local+partner recommended)
timed.servers                10.18.150.31,10.18.152.31 (same value in local+partner recommended)
timed.window                 0m         (same value in local+partner recommended)

Able to reach ntp Ip from filer.

Everything looks fine on config part - still not sure what is going wrong

Can someone help please

max time skew should be 2m, especially in CIFS

You're NTP servers are what?

hi,

we are using the mentioned storage for NFS shares.

The NTP server is on Linux.

Other storage devices are working fine with same NTp Settings.

Problem is just this NetApp mentioned..

When is the last time the controller has been rebooted? I'm just curious.

Also, I would use the date command to set the date and then turn off time off and on

options timed.enable off

options timed.enable on

and then if that still doesn't work, run a packet trace from the vif to the time server

Thanks for reply guys.

The issues was with the communication with with NTP server

upon checking the route -s, there was no route shown - to establish the connection to NTP server.

Hence executed command route add to establish communication of filer with the NTP server.
