here is running Windows 2016 cluster and installed SQL server 2016 cluster. I have now have 4 nodes cluster.
Originally there are two failover instance installed in the cluster. And each instance has 3 cluster disk resources . Today I remove one of the SQL instance by removing cluster node one by one. The instance successfully removed.
Then I try to install another sql server failover instance, however got this error in the rule check page:
"
Rule "Microsoft Cluster Service (MSCS) cluster verification errors" failed.
The cluster either has not been verified or there are errors or failures in the verification report. Refer to KB953748 or SQL Server Books Online for more information.
"
Then I run the cluster validation, and it failed on the following error:
I found that ONE of the cluster disk still keep ONLINE in one of the node, however, in failover cluster management view, it show offline.
any work around ? reason for this ?
