You can add advanced settings to SMB-enabled file systems while creating a file system.
Setting | Description |
---|---|
Sync Writes Enabled | When you enable the synchronous writes option for a Windows (SMB) or multiprotocol file system, the storage system performs immediate synchronous writes for storage operations, regardless of how the SMB protocol performs write operations. Enabling synchronous write operations enables you to store and access database files (for example, MySQL) on storage system SMB shares. This option guarantees that any write to the share is done synchronously and reduces the chances of data loss or file corruption in various failure scenarios, for example, loss of power. This option is disabled by default.
NOTE:The synchronous writes option can have a significant impact on performance. It is not recommended unless you intend to use Windows file systems to provide storage for database applications.
|
Oplocks Enabled | (Enabled by default) Opportunistic file locks (oplocks, also known as Level 1 opslock) enable SMB clients to buffer file data locally before sending it to a server. SMB clients can then work with files locally and periodically communicate changes to the storage system rather than having to communicate every operation over the network to the storage system. This feature is enabled by default for Windows (SMB) and multiprotocol file systems. Unless your application handles critical data or has specific requirements that make this mode or operation unfeasible, leaving the oplocks enabled is recommended. The following oplocks implementations are supported:
|
Notify on Write Enabled | Enable notification when a file system is written to. This option is disabled by default. |
Notify on Access Enabled | Enable notification when a file system is accessed. This option is disabled by default. |
Enable SMB Events publishing | Enable the processing of SMB events for this file system. |
