- You configure the Scale-Out File Server (SOFS) role on a server that's running Window Server 2012 R2.
- You have server applications and clients that access file shares frequently.
- The applications and clients open many short-lived sessions in which they connect, authenticate, change files, and close the session immediately.
Additionally, when users try to connect to SOFS shares, they receive the following error message:
You also see a very high handle count in Lsass.exe on both the coordinator and non-coordinator nodes of the cluster.
Note If you failover the disk resource to another node, the issue temporarily does not occur.
The CSV File System uses the SMB protocol to keep metadata information consistent between the cluster nodes. A high volume of metadata changes generate many SMB sessions between the non-coordinator and coordinator nodes of the cluster and exhaust the SMB table on the coordinator node.
Note The SOFS role should not be used if the workload generates an exceptionally high number of metadata operations, such as opening and creating new files or renaming existing files.
