Modifying Properties of a CIFS Homedir Share

Modifying Properties of a CIFS Homedir Share

This operation enables you to modify the properties of a CIFS Homedir share to improve the sharing efficiency.

Procedure

  1. Log in to DeviceManager.
  2. Choose Provisioning > Share > CIFS Homedir.
  3. Select the CIFS Homedir shared resource whose properties you want to modify.
  4. Click Properties.

    The CIFS Homedir Share Attribute dialog box is displayed.

  5. Modify the following parameters based on site requirements.

    Table 4-29 describes the related parameters.

    Table 4-29 Parameters for a CIFS Homedir share

    Parameter

    Description

    Value

    Description

    Description of the created CIFS Homedir share.

    [Value range]

    The description can be left blank or contain up to 255 characters.

    [Example]

    Share for user 1.

    Oplock

    Opportunistic locking (Oplock) is a mechanism used to adjust cache policies of clients, improving performance and network utilization.

    This function is not recommended in the following scenarios:

    • Scenarios that have high requirements for data integrity: Local cache loss will occur if your network is interrupted or your client breaks down after Oplock is enabled. If the upper-layer service software does not have a mechanism to ensure data integrity, recovery, or retry, data loss may occur.
    • Scenarios where multiple clients access the same file: If Oplock is enabled, the system performance will be adversely affected.

    [Default value]

    Enabled

    Notify

    After this function is enabled, a client's operations on a directory, such as adding a sub-directory, adding a file, modifying the directory, and modifying a file, can be detected by other clients that are accessing this directory or its parent directory.

    [Default value]

    Enabled

    Offline Cache Mode

    Cache files to be accessed in different offline cache modes to local clients so that files can be operated offline. The following offline cache modes are supported:

    • None

      Files and programs in the shared directory cannot be cached to local clients. Therefore, these files and programs cannot be operated offline. This mode prevents the offline file function of clients from creating duplicates of files in the shared directory.

    • Manual

      Specified files and programs in the shared directory can be cached to local clients and operated offline.

    • Documents

      If a user accesses the shared directory and opens a file or program in the shared directory, the file or program is automatically cached to a local client so that users can operate it offline. Files and programs that can be operated offline are saved in the clients' cache and synchronized with those in the shared directory until the cache is full or users delete them. Files and programs that have not been opened cannot be cached locally.

    • Programs

      Performance is optimized based on the Documents mode. If an executable file (EXE or DLL) in the shared directory is executed by a local client, the file is automatically cached to the client. If the client needs to run the executable file online or offline next time, it accesses the cached file instead of that in the shared directory.

    NOTE:

    The offline file function of clients must be enabled so that files and programs can be automatically cached.

    [Default value]

    Manual

    CA

    This option is for SMB3.0 continuous availability, only applied to the share for Hyper-V. This feature depends on Oplock, ensure that Oplock is enabled.

    [Default value]

    Disabled

    Security Restriction

    After this function is enabled, only the added IP addresses can be used to access devices. After this function is disabled, all IP addresses can be used to access devices.

    [Default value]

    Disabled

    Create Default ACL

    This function creates a default ACL (full control rights to everyone; applied to the current directory, its subdirectories, and files in them) for a shared CIFS root directory if the directory has no ACL. You can change the default ACL in follow-up operations. If you want to retain the UNIX MODE rights, disable this function.

    [Default value]

    Enabled

    File Name Extension Filtering

    After this function is enabled, the types of files that users access on a CIFS share are controlled.

    NOTE:
    • SMB2 and SMB3 support file name extension filtering while SMB1 does not.
    • If file name extension filtering is enabled, the enabling and modification will take effect when the next new CIFS Homedir service request is initiated (such as refreshing directories, creating files, renaming files, performing failover retries, and querying file attributes).

    [Default value]

    Disabled

    ABE

    After this function is enabled, files and folders that users have no access permission are not displayed.

    NOTE:

    SMB2 and SMB3 support ABE while SMB1 does not support it.

    [Default value]

    Disabled

    Show Previous Versions

    After this function is enabled, clients can show and roll back historical versions.

    [Default value]

    Enabled

    Show Snapshot

    If this function is enabled, clients can show and traverse snapshot directories.

    [Default value]

    Enabled

    Audit Log

    After the audit function is enabled, the system can record audit logs of a shared directory. The audit log items include Open, Create, Read, Write, Close, Delete, Rename, Obtain properties, Set properties, Obtain security properties, Set security properties, Obtain extension properties, and Set extension properties. After the audit function is enabled, by default, the system records Create, Write, Delete, and Rename operations of the shared directory.

    NOTE:

    Before configuring this function, choose Settings > Monitor Settings > Audit Log Settings, and enable Record Log.

    [Default value]

    Disabled

  6. Click OK.

    The Execution Result dialog box is displayed.

  7. Click Close to finish modifying the CIFS properties.
