How to Expand a Trans Metadevice (DiskSuite Tool)

You can expand a master device within a trans metadevice as long as the master device is a metadevice. To expand a master that consists of a slice, you must tear down (clear) the trans, put the slice into a metadevice, then recreate the trans.

Use this procedure to expand a master device that makes up the trans metadevice.

If the master device is a mirror, you need to expand each submirror.

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 an existing Trans Metadevice object in the Objects list.

   The object appears on the canvas.

3. Expand the master device.

   • Concat or Stripe: see "How to Expand an Existing Concat/Stripe (DiskSuite Tool)"

   • Mirror: see "How to Expand a Mirror (DiskSuite Tool)"

   • RAID5 metadevice: see "How to Expand a RAID5 Metadevice (DiskSuite Tool)"

4. If the log is not mirrored, a dialog box appears. Click OK.

5. Click the top rectangle of the Trans Metadevice object then click Commit.

   Mounted file system: 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 trans metadevice was committed, display the Configuration Log.
