Description Numan Siddique 2020-01-08 06:56:07 UTC
Description of problem:

If active ovsdb-server doesn't respond to the echo request from the standby ovsdb-servers (in the active/passive deployment) within 5 seconds, the standby ovsdb-server disconnects. And if active ovsdb-server is heavily loaded then this could result in continous loop of connect/disconnect.

Comment 12 Jianlin Shi 2020-02-03 03:05:26 UTC
Hi Numan,

how could we reproduce the issue?

Comment 14 Jianlin Shi 2020-02-05 12:47:33 UTC
reproduced with following steps:

install pcs on two systems:
yum -y install pcs pacemaker fence-agents-all

setenforce 0
systemctl start openvswitch

then setup pcs with following script:

setenforce 0
systemctl start openvswitch
ip_c1=20.0.30.26
ip_c2=20.0.30.25
ip_v=20.0.30.100
(sleep 2;echo "hacluster"; sleep 2; echo "redhat" ) |pcs cluster auth  $ip_c1 $ip_c2
sleep 5
pcs cluster setup --force --start --name my_cluster $ip_c1 $ip_c2
pcs cluster enable --all

pcs property set stonith-enabled=false
pcs property set no-quorum-policy=ignore
pcs cluster cib tmp-cib.xml
sleep 10
cp tmp-cib.xml tmp-cib.deltasrc
pcs resource delete ip-$ip_v
pcs resource delete ovndb_servers-master
sleep 5
pcs status

pcs -f tmp-cib.xml resource create ip-$ip_v ocf:heartbeat:IPaddr2 ip=$ip_v op monitor interval=30s
sleep 5
pcs -f tmp-cib.xml resource create ovndb_servers  ocf:ovn:ovndb-servers manage_northd=yes master_ip=$ip_v nb_master_port=6641 sb_master_port=6642 inactive_probe_interval=180000 master
sleep 5
pcs -f tmp-cib.xml resource meta ovndb_servers-master notify=true
pcs -f tmp-cib.xml constraint order start ip-$ip_v then promote ovndb_servers-master
pcs -f tmp-cib.xml constraint colocation add ip-$ip_v with master ovndb_servers-master

#pcs -f tmp-cib.xml constraint location ip-$ip_v prefers $ip_c2=1000
#pcs -f tmp-cib.xml constraint location ovndb_servers-master prefers $ip_c2=1000
#pcs -f tmp-cib.xml constraint location ip-$ip_v prefers $ip_c1=500
#pcs -f tmp-cib.xml constraint location ovndb_servers-master prefers $ip_c1=500

pcs cluster cib-push tmp-cib.xml diff-against=tmp-cib.deltasrc


then copy ovnnb_db.db in bz1788906 to /etc/openvswitch
then restart resource with: pcs resource restart ovndb_servers
