Hi experts,
I'm new to SQL Server. Nowadays I want to use SQL Server on Linux. and I tested the failover SQL Server on Linux and Windows Server.
And I found out that downtime for failover is too long on linux.
Env for windows
OS : windows server 2016 with AD (3node)
SQL : SQL Server 2017
Failover Downtime : 10s
Env for Linux
OS : ubuntu 16.04 with pacemaker (3node)
SQL : SQL Server 2017
Downtime : 40s(I tested it on centos again and I got the same result)
So I doubt thepacemaker configuration or something on Linux. I don't know where I should see.
I followed the document (https://docs.microsoft.com/en-us/sql/linux/sql-server-linux-create-availability-group?view=sql-server-linux-2017)
Could you give me some advice? Do you need more information to solve or check? Tell me.
Thank you.
