### Expanding existing distributed setup

MinIO supports expanding distributed erasure coded clusters by specifying new set of clusters on the command-line as shown below:

```sh
export MINIO_ROOT_USER=<ACCESS_KEY>

  }

  /** Returns the index, or UNSET if the pointer is "null" */
  private static int getNext(long entry) {
    return (int) entry;
  }

  /** Returns a new entry value by changing the "next" index of an existing entry */
  private static long swapNext(long entry, int newNext) {
    return (HASH_MASK & entry) | (NEXT_MASK & newNext);
  }

  void ensureCapacity(int minCapacity) {
    if (minCapacity > entries.length) {

        Path nonExistentDir = tempDir.resolve("non-existent");
        themeHelper.closeQuietly(nonExistentDir);
        // Should not throw exception
        assertTrue(true);
    }

    @Test
    public void test_closeQuietly_existingDirectory() throws IOException {
        Path existingDir = tempDir.resolve("existing");
        Files.createDirectory(existingDir);

            throwValidationError(messages -> messages.addErrorsCrudFailedToCreateInstance(GLOBAL), this::asEditHtml);
        });
        return redirect(getClass());
    }

    /**
     * Updates an existing group.
     *
     * @param form the edit form
     * @return HTML response after update
     */
    @Execute
    @Secured({ ROLE })
    public HtmlResponse update(final EditForm form) {

        lenient().when(autoCloseableMockFileHandle.isValid()).thenReturn(true);
        when(autoCloseableMockFileHandle.getInitialSize()).thenReturn(50L); // Existing file with 50 bytes

        when(autoCloseableMockTreeHandle.getSendBufferSize()).thenReturn(65536);

        // When
        outputStream = new SmbFileOutputStream(mockFile, true);

        // Then

Make sure you use a supported label from the [latest-changes list of labels](https://github.com/tiangolo/latest-changes#using-labels):

* `breaking`: Breaking Changes
    * Existing code will break if they update the version without changing their code. This rarely happens, so this label is not frequently used.
* `security`: Security Fixes

 * together. Any creation method that would customarily respect insertion order (such as {@link
 * #copyOf(Multimap)}) instead preserves key-grouped order by inserting entries for an existing key
 * immediately after the last entry having that key.
