Problem synchronizing the storage system time with time server.

[ Edited ]

We have two filers model FS2240-4 running version 8.1.3 7 mode. Both the filers are timed.enabled , ntp to internal dc time server, have same value. But filers time keeps drifting. I cannot see any logs in message logs too? Please if can get advise how do I troubleshoot the issue?

Hi,

 

Just try using the Host name of the NTP server in Timed.servers rather than an Ip or Alias and check if it resolves the issue.

 

Hope this helps.

Hello,

this can be caused by NTP server being "not precise enough" for Data ONTAP. Check the KBs

https://kb.netapp.com/support/index?page=content&id=1012660 (the "ntpq" part can be run from ONTAP systemshell)

Thanks Renifa, i tried changing it to hostname but am afraid it still won't synchronize. Any other suggestion?

  • Make the Kerberos version 5 authentication protocol work.
  • Provide loose sync time for client computers."

Thanks Georgevj,
I did opened a support case with NeApp. They  recommended the steps as recommended by Harry_Redl in his post.

 

The ntpq analyzed issue "Flash=400 peer_dist. Peer synchronization distance exceeded."

 

As recommend in https://kb.netapp.com/support/index?page=content&id=2015314&actp=LIST, changed the precision of time server , but am afraid still won't synchronize.

 

The case is opened with Netapp. They too are investigating and am awaiting update since last 5 days.

 

Any advise?

Did you check ntpq status again? is it still Flash=400 or did it change to something else?

Hi Georgevj,

I have checked. It is still same. Error Flash=400.
