I have NSO HA setup with two nodes. I've noticed master IP become unresponsive after a time period. I'm running NCS 3.3.3.
While master IP is unresponsive, the interface is up and HA status is good too and also I can access both master and slave nodes individually.
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000

inet 10.114.209.215/27 scope global secondary eth0:ncsvip

admin@ncs# show ha-cluster
My HA configuration is as below.
ha-cluster auto-start enable
ha-cluster master-ip enable
ha-cluster master-ip vip 10.114.209.215
ha-cluster master-ip member tsoe-nso-master.cisco.com interface eth0 !
ha-cluster master-ip member tsoe-nso-slave.cisco.com interface eth0 !
ha-cluster members tsoe-nso-master.cisco.com address 10.114.209.213
ha-cluster members tsoe-nso-slave.cisco.com
"ncs --status" shows HA is in good shape while master IP is unresponsive.

I’m running this two nodes in OpenStack environment with RHEL 7 OS image and virtual IP is assigned as an address pair address. Any help will be appreciated.
