Flexible Storage Sharing (FSS) enables network sharing of local storage, cluster wide. You can use both DAS disks and SAN disks (LUNs) in any storage pool that you define. Multiple storage pools can have DAS disks, and any storage pool can have a mix of DAS and SAN disks. FSS allows network shared storage to co-exist with physically shared storage, and file systems can be created using both types of storage.
For FSS to work properly, ensure that the DAS disks in the servers are compliant with SCSI standards, which guarantees having a unique disk identifier (UDID). If you do not have unique UDIDs, you may run in to unexpected behavior.
Use the following CLISH command to list all of the disks and their unique UDIDs. The UDID is displayed under the ID column.
