HA failover to member 2 - FULLSYNC PNOTE - Manually disabled sync

[DekPlent]

Hi All,

I have had a pair of Quantum spark 1590s setup in a cluster for the past 2 months and within that time we have see two failovers from member 1 to 2.

When failing back to member 1 within a day or so it will fail to 2.  The messages file is rotated and so I wasn't able to get to the messages file in time. but cphaprob shows:

[Expert@Gatekeeper1]# cphaprob show_failover

Last cluster failover event:
   Transition to new ACTIVE:   Member 1 -> Member 2
   Reason:                     FULLSYNC PNOTE - Manually disabled sync
   Event time:                 Wed Mar 30 22:17:17 2022

Cluster failover count:
   Failover counter:           6
   Time of counter reset:      Wed Mar 30 22:17:22 2022 (reboot)


Cluster failover history (last 20 failovers since reboot/reset on Wed Mar 30 22:17:22 2022):

 No. Time:                     Transition:           CPU:  Reason:

Searching for the reason for failover turns up this post from some years back: https://community.checkpoint.com/t5/General-Topics/Issue-on-the-sync-interface/td-p/30640
but I dont think that the interfaces are flapping as in that example and hoping that there is not a specific hardware issue with member1

I was just wondering if anyone what message specifically means.

The sync interfaces are plugged into a switch and not a direct cable connection in this instance.

Thanks for any info / tips/ advice

Look into /var/log/log/sfwd.el* and /var/log/messages for errors !

Thanks, I will look in /var/log/log/sfwd.el*  and /var/log/messages if quick enough before log rotate.

Do you know what the definition of this error means -

FULLSYNC PNOTE - Manually disabled sync

Thanks and Regards
