FMC HA sync failed message

LuigiDiFronzo9542 — Wed, 31 May 2023 19:38:33 GMT

We have 2 FMC ver 7.0.5 in HA. They're located in remote sites. Sometimes we lost connection and logically the FMCs indicate a sync error. After a while the messages clear as expected.

Since yesterday afternoon we began to observe the sync error . We test a ping from one FMC to the other and we get response.

The error is:

"FMC HA Status:

HA Sync failed:

Database synchronization failed on the local Management Center

Database synchronization failed on the local Management Center"

What else can be checked?

Thanks.

Step 1	Log into one of the FMCs that you paired using high availability.
Step 2	Choose System ( ) > Integration.
Step 3	Choose High Availability.
Step 4	Choose Resume Synchronization.

Hello,

In the Standby FMC there is no Resume Synchronization button. The button is the Pause Synchronization.

There is also the following image at the FMC Standby:

about same issue but without workaround and without mention which ver. this bug is fixed.
so it better to open TAC.
Thanks
