Hi all, If you can not understand what i'm saying,I apologize for my poor English.

 

I have a ha cluster using 1500D with version 5.0.14 and without ntp server.

When I adjust system time to real time.My slave forti starting appear error log like

 

date=2016-11-07 time=11:16:55 logid=0100035010 type=event subtype=system level=error vd="root" msg="HA slave sync failed in 3 turns"

 

Logs like this appear 2-3 times daily.

After I config time before change,this log still appear.

I've tried re-build HA cluster but looks like didn't work.

 

Really need help.Thanks

 

I've show checksum in both of forti,and they are the same

Aaron, have you compared the entire config ("diff") between them? You might find something if you do. That how we found an HA issue (not harmful) with 5.2.9.

I see that it's flagged as an 'error' but if the checksums are identical then there's nothing to worry about. Time keeping is essential with clusters as some decisions are based on i.e. the uptime count. So cluster members should be in sync with a time source.

Depending on the firmware version you could make one member an NTP server and hook the other up to it. Absolute time wouldn't necessarily be correct but relative time difference would be minimal.

I'm not sure v5.0 has got that feature, but that's easy to spot in the GUI (Status - setting time): there should be a checkbox for 'act as NTP server'. In v5.2 it's included, for sure.

Hi Ede,

Thanks for reply.

I know that system time will be sync by cluster,I've been check via CLI get system status.

But I'm still wonder why sync failed after change system time?

Uptime is calculator by system time,I change both time on Forti but make sync fail.

This really confused me,how should I fixed it ?

 

 

BTW,I'm not consider build NTP server right now

As I said, I don't see any reason to change anything at the moment. Yes, there is a log message and no, it doesn't mean the cluster operation is in danger.

Do you change the local time often? If you manually adjust the time, is that on the master unit only?
