How to Expand an Existing Concat/Stripe (DiskSuite Tool)

This task assumes that you are adding an additional stripe to an existing concatenation or stripe. If you need to recreate a concatenated stripe as part of disaster recovery, refer to "How to Recreate a Stripe or Concatenation After Slice Failure (DiskSuite Tool)".

A concatenated stripe enables you to expand an existing stripe or concatenation. For example, if a stripe has run out of space, you can make it into a concatenated stripe, and expand it without having to back up and restore data.

If you drag multiple slices into an existing Concat/Stripe object, you are given the optional of making the slices into a concatenation or a stripe.

1. Make sure you have met the prerequisites ("Prerequisites for Maintaining DiskSuite Objects") and have read the preliminary information ("Preliminary Information for Expanding Slices and Metadevices").

2. Double-click the Concat/Stripe object in the Objects list.

   DiskSuite Tool displays the Concat/Stripe object on the canvas.

3. Click Slices to open the Slice Browser window.

4. Select the slice(s) you want to concatenate as another stripe. Drag the slice(s) to the top rectangle of the metadevice object.

   If you drag multiple slices, a dialog box prompts you to choose how you want to add the slices, either as a stripe or a concat. Click either Stripe or Concat.

   The additional striped metadevice or concatenated metadevice is added at the bottom of the Concat/Stripe object.

5. Click the top rectangle of the Concat/Stripe object. Then click Commit.

   Mounted file system only: A GrowFS dialog box appears. Click Grow Now to begin running the growfs(1M) command. A GrowFS Running message appears. If you click Terminate GrowFS, the command is aborted. Otherwise, when the growfs(1M) command finishes, you are returned to the DiskSuite Tool window.

   Application using the raw device: Such applications must have their own method, outside of DiskSuite, to recognize the expanded space.

6. To verify that the concatenated stripe was committed, display the Configuration Log.

Example -- Concatenated Stripe Object

This example shows a striped metadevice consisting of two slices to which another slice has been added. The Concat/Stripe object displays the slices in two stripe rectangles labeled stripe 0 (the original stripe) and stripe 1 (the added stripe).
