Background:
There are 4 physical machines, with two virtual machines running on each
physical machine. lustre-mds-nodexx runs the Lustre MDS server, and
lustre-oss-nodexx runs the Lustre OSS service. Each virtual machine is directly
connected to two network interfaces, service1(ens6f0np0) and
service2(ens6f1np1). Pacemaker is used to ensure high availability of the
Lustre services.
Software versions:
Lustre: 2.15.5
Corosync: 3.1.5
Pacemaker: 2.1.0-8.el8
PCS: 0.10.8
Operation:
During testing, the network interfaces service1 and service2 on
lustre-oss-node40 and lustre-mds-node40 were repeatedly brought up and down
every 20 seconds (to simulate a network failure).
for i in {1..10}; do date; ifconfig ens6f0np0 down && ifconfig ens6f1np1 down;
sleep 20; date; ifconfig ens6f0np0 up && ifconfig ens6f1np1 up; date;sleep 30
Issue:
Theoretically, lustre-oss-node40 and lustre-mds-node40 should have been fenced,
but lustre-mds-node32 was fenced instead.
