Hi, I have a 2 Node active-passive SQL 2014 Cluster.
Currently, there are 4 Shared Disks on this Cluster - 2 for Quorums and 2 - 1 each for Data and Log. (This is what I see on the Cluster Manager).
Now I would like to add one more instance on the same Cluster. How do I go about doing this?
I attempted going to Node 1 - and initiating the SQL Cluster Installation, but after a few steps, I got a Cluster Validation Error and I had to come out. Infact, after that - all permissions for the SQL Service Account was removed from the SQL Data folder (where you have all MDF, LDF files) and it was a big headache to bring it back!
I dont want to have any scenario like this again and hence would like to know the proper and correct steps to do this.
Please advise!
