Modifying the Properties of File Name Extension Filtering Rules

Modifying the Properties of File Name Extension Filtering Rules

File name extension filter rules can control the types of files that users access on a CIFS Homedir share.

Procedure

  1. Log in to DeviceManager.
  2. Choose Provisioning > Share > CIFS Homedir.
  3. From the CIFS Homedir share list, select the CIFS Homedir share whose file name extension filtering rule will be modified.

    NOTE:

    If file name extension filtering rules are modified, the 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).

  4. Add a file name extension filtering rule.

    NOTE:

    File name extension filtering rules are valid only for the current share.

    1. Click the File Name Extension Filtering Rule tab.
    2. Click Add.

      The Add File Name Extension Filtering Rule dialog box is displayed.

    3. In File Name Extension, specify the file name extension (file type) to be filtered.
      NOTE:
      • The file name extension contains 1 to 127 visible ASCII characters, and contains only digits, letters, space, and special characters (!\"#$%&\'()*+\,-.\/\:;\<=\>?@[\\]^_`{\|}~). Wildcard character * can only be the last character. For example, the file name extension can be txt, TXT, T?X, or Tx*.
      • A share supports up to 128 filtering items.
      • A storage system supports up to 120,000 filtering items.
      • It is recommended that one share have a maximum of seven file name extension filtering rules, and one file name extension contain 1 to 32 characters (excluding wildcards). The recommended configurations minimize any adverse impact on the CIFS service performance. If the recommended configurations are not used, CIFS performance may greatly deteriorate.
      • When configuring a file name extension filtering rule, ensure that the rule does not affect the storage of temporary files that may be generated when application software is running. For example, some application software may generate files with the .tmp file name extension. In this case, add the .tmp extension to the file name extension filtering rule. For details about specific temporary file name extension of application software, contact the relevant software vendor.
    4. Select a permission rule from the Rule Type drop-down list.
      NOTE:
      • Denied only: Users do not have permission to access files with the specified extension.
      • Allowed only: Users have permission to access files with the specified extension.
    5. Click OK.

      The Success dialog box is displayed, indicating that the filtering rule is successfully added.

    6. Click OK.

      On the File Name Extension Filtering Rule tab page, query the added filtering rule.

  5. Modify an existing file name extension filtering rule.

    NOTE:

    File name extension filtering rules are valid only for the current share.

    1. Click the File Name Extension Filtering Rule tab.
    2. Select the filtering rule to be modified and click Properties.

      The Properties of File Name Extension Filtering Rule dialog box is displayed.

    3. In File Name Extension, add a file name extension (file type) to be filtered.
      NOTE:
      • The file name extension contains 1 to 127 visible ASCII characters, and contains only digits, letters, space, and special characters (!\"#$%&\'()*+\,-.\/\:;\<=\>?@[\\]^_`{\|}~). Wildcard character * can only be the last character. For example, the file name extension can be txt, TXT, T?X, or Tx*.
      • The maximum number of filtering items supported by a share is 128.
      • The maximum number of filtering items supported by a storage system is 120,000.
      • It is recommended that one share have a maximum of seven file name extension filtering rules, and one file name extension contain 1 to 32 characters (excluding wildcards). The recommended configurations minimize any adverse impact on the CIFS service performance. If the recommended configurations are not used, CIFS performance may greatly deteriorate.
      • When configuring a file name extension filtering rule, ensure that the rule does not affect the storage of temporary files that may be generated when application software is running. For example, some application software may generate files with the .tmp file name extension. In this case, add the .tmp extension to the file name extension filtering rule. For details about specific temporary file name extension of application software, contact the relevant software vendor.
    4. Select a new permission rule from the Rule Type drop-down list.
      NOTE:
      • Denied only: Users do not have permission to access files with the specified extension.
      • Allowed only: Users have permission to access files with the specified extension.
    5. Click OK.

      The Success dialog box is displayed, indicating that the filtering rule is successfully modified.

    6. Click OK.

  6. Delete an existing file name extension filtering rule.

    NOTE:

    When removing a file name extension filtering rule, ensure that the removal does not affect the storage of temporary files that may be generated when application software is running. For details about specific temporary file name extension of application software, contact the relevant software vendor.

    1. Click the File Name Extension Filtering Rule tab.
    2. Select the filtering rule to be deleted and click Remove.

      The Confirm dialog box is displayed.

    3. Click OK.

      The Execution Result dialog box is displayed.

    4. Click Close.

      The file name extension filtering rule is successfully deleted.
