We have a pair of 2012 R2 servers clustered together with SQL 2012. Recently when we attempt to attach a database and associated log file we get the attached error. We are unaware of or even if any changes were made to this cluster, and there are no current cluster errors displayed.
We have found multiple articles stating this is a dependency issue but we are unsure where this dependency is missing? SQL Server resource, Agent resource, disk resource, or all the above.
We are going to failover the cluster to see if the behavior persists on the other node but I was hoping others had recommendations as to what this can be.
