Stat Server HA

[a.jay]

Hi guys!
I have a problem 
I installed the second StatServer. Set it in the mode of Warm Standby. Both StatServer added the option accept-clients-in-backup-mode = yes. DataSourcer single primary. When I do Switchover on backup StatServer, DataSourcer can not connect to the backup StatServer (writes in the logs). In what may be the problem?

Could be a lot of things

But have you tried the basics? - is the network OK? - can the datasourcer server resolve the hostname of the new stat-server? Can you ping the statserver from the datasourcer?

If you stop both Stat Servers and then start your new one on its own, does datasourcer connect?

What does the logs say? Is the backup statserver ok? Show some logs

Today, I manipulated with restarting DataSourcer and both StatServer. For the second time it's worked.
Thank you for the tip!
