About NSO HA Qusestions

 

Hi,

 

After I deply NSO HA, test its behaviors and find some questions as follows,

 

 

1 when occur failover, one slave will update to be master, but other slave will not automatically transition to slave to the new master.

 

In this time, only one nso node work and not have nso node as backup. I think this behavior is not we want. Do NSO have roadmap to fix this issue ?

 

2 find that occur two VM that have configed VIP, but only one VIP can work. Work steps are as follows.

 

(1) config HA, The status is OK.

 

  (2) master(paris_m) is down, one slave(paris_s1) change to master.

 

(3)paris_m is up, and run ha command activate in paris_m.

 

paris_m:

 

admin@ncs# show ha

 

CURRENT

 

NAME HA ROLE

 

-------------------

 

paris_m master

 

paris_s1 unknown

 

paris_s2 slave

 

 

paris_s1:

 

admin@ncs# show ha

 

          CURRENT

 

NAME HA ROLE 

 

-------------------

 

paris_m unknown 

 

paris_s1 master  

 

paris_s2 unknown

 

In this time, in paris_m and paris_s1 are have eth0:ncsvip, but when access vip, actually access paris_s1.

 

Why have this case, why not access paris_m ?

 

 

---------

 

Regards,
