Each Host button (as shown on the left)
denotes a machine participating
in an xFS cluster. Clicking on a host button makes this machine the current Active Host. The active host is shaded (as shown on the right). There is always one and only one active host. |
|
Click on a Create button to create a file block. |
|
The Operation Control specifies what operation is to be performed when a file block is clicked. |
|
Click on a File Block to perform a file system
operation. For example, when the current active host is machine "5", and the Operation Control has a value of "read", then clicking on a block named "4" means: host "5" is reading file block "4". |

Click on the Flush button to force dirty blocks on a host to disk. |
