Windows Server 2016 Technical Preview 4 Cluster Build and SQL Server Installation – standalone SQL installs with Storage Replica,floating IP and manual failover

Posted: January 12, 2016 | Author: | Filed under: Uncategorized, Windows Server 2016, Windows Storage Replica | Leave a comment

Following on from the previious attempt at Windows Server 2016 Storage Replica with Cluster Shared Volumes which did not work completely I tried a manual approach.

I did not give up, what if we do not use Windows Clustering but do all the steps manually?

This is 2 standalone SQL Servers both installed with data on the F: drive and then Storage Replica used to keep them in sync.

We

– add a DNS entry and a floating IP address
– manually setup Storage Replica
– manually handle stopping/starting services, failing over/back the Storage Replica and moving the floating IP

does it work?

The answer is yes-ish if you are careful and ignore the warning about data loss!

There does not seem to be an option to failover (Set-SRPartnership) synchronously to guarantee no data loss!

Also we could do with an option to validate everything is in sync or resync even if we would have to suspend writes to allow this.

SQL Server Clustering (FCI) setup using Storage Replica

Posted: January 9, 2016 | Author: | Filed under: Uncategorized, Windows Cluster Shared Volumes, Windows Clustering, Windows Storage Replica | Leave a comment

I have been playing with SQL Server Clustering (FCI) setup with a Widnows Server 2016 Preview 4 and Windows Storage Replica.

This involves local storage and Cluster Shared Volume with Replication Enabled.

This is incomplete – if Node 1 goes offline the SQL Server role fails!
