Hi Huu The Truong,
I am trying to reproduce the issue by splitting the network using iptable
rules. I am not able to reproduce the issue.
I created the 2 partitions of network by using this iptable rule.
iptables -I INPUT -s 192.168.56.122 -j DROP; iptables -I INPUT -s
192.168.56.107 -j DROP;
one partition have SC-1(ACTIVE) and PL-3(payload).
another partition have SC-2(ACTIVE) and PL-4(payload).
After all nodes comes up successfully and i created the objects , i deleted
the created iptable rules using
iptables --delete INPUT 2;iptables --delete INPUT 1
then both controllers detect each other as active and split brain scenario
occurred and nodes are rebooted.
But i didn't see any "Quick local node rebooting, Reason: Used to be on another
partition. Rebooting..." error in my logs.
Can you please let me know how to split the network into partitions and also
let me know the cluster size of both the partitions.
Thanks
Mohan

Split network into two partitions. On each partition, create a dummy object.
During merge network back has happened twice the reboot node.
The first reboot node:
2021-09-07 12:20:06.926 SC-7 osafimmnd[376]: NO Used to be on another
partition. Rebooting...
2021-09-07 12:20:06.935 SC-7 osafamfnd[431]: NO AVD NEW_ACTIVE, adest:1
2021-09-07 12:20:06.935 SC-7 osafimmnd[376]: Quick local node rebooting,
Reason: Used to be on another partition. Rebooting...
2021-09-07 12:20:06.952 SC-7 opensaf_reboot: Do quick local node reboot
At the second, this reboot is unexpected:
2021-09-07 12:20:11.963 SC-7 osafimmnd[376]: NO Used to be on another
partition. Rebooting...
2021-09-07 12:20:11.963 SC-7 osafimmnd[376]: Quick local node rebooting,
Reason: Used to be on another partition. Rebooting...
2021-09-07 12:20:11.989 SC-7 osafclmna[333]: NO
safNode=SC-7,safCluster=myClmCluster Joined cluster, nodeid=2070f
2021-09-07 12:20:11.992 SC-7 opensaf_reboot: Do quick local node reboot
2021-09-07 12:20:12.022 SC-7 opensafd[305]: ER Service RDE has unexpectedly
