We have a 2 node SQL Availability Group on a Windows 2016 Std Cluster.
SQL Server reported the databases suspect after the data drives on both servers appeared to have been formatted.
On one of the servers we found the following events:
Event ID 7036 on 7/26/2019 at 9:37:55AM
Event ID 98 on 7/26/2019 at 9:38:12AM
Event ID 98 on 7/26/2019 at 9:38:13AM
These appear to indicate that the drive was formatted.
We have tested and found that using the Powershell "Format-Volume" command (Run locally or remotely) against one server causes the same drive on both nodes in the Cluster/AG to be formatted.
One possible cause is a server build script has been run with incorrect server details and we are investigating this possibility.
My questions are:
Has anyone experienced drives being "Formatted" simultaneously across nodes in a Clustered SQL AG?
Is the formatting of drives on an Availability Group supposed to affect all nodes? I've not found documentation to explain this.
