Server: Msg 5184, Level 16, State 1, Line 1
Only formatted files on which the cluster resource of the server has a dependency can be used.
For all those who got this error message after removing a node from a clustered SQL instance: for some reason the node-removal operation also removes the disk dependency in SQL resource definition (at least that was my experience in SQL version 2008 running on 2008 R2). The solution is to open Cluster Manager's SQL resource definition and add the clustered disk dependency manually, under the cluster name using 'AND' dependency.
Why is the SQL removing that dependency when you remove a node?
