9.2. Example: create a region

This section tells how to create a region with EVMS by providing instructions to help you complete the following task.

Example 9-1. Create "Sample Region"

Given the container "Sample Container," which has a freespace region of 8799 MB, create a data region 1000 MB in size named "Sample Region."

9.2.1. Using the EVMS GUI

To create a region, follow these steps:

  1. Select Actions->Create->Region

  2. Select the LVM Region Manager. Click Next.

    NoteNOTE
     

    You might see additional region managers that were not in the selection list when you were creating the storage container because not all region managers are required to support containers.

  3. Select the freespace region from the container you created in Chapter 8. Verify that the region is named lvm/Sample Container/Freespace. Click Next.

    The fields in the next window are the options for the LVM Region Manager plug-in, the options marked with an "*" are required.

  4. Fill in the name, Sample Region.

  5. Enter 1000MB in the size field.

  6. Click the Create button to complete the operation. A window opens to display the outcome.

Alternatively, you can perform some of the steps for creating a region with the GUI context sensitive menu:

  1. From the Regions tab, right click lvm/Sample Container/Freespace.

  2. Click Create Region.

  3. Continue beginning with step 4 of the GUI instructions.

9.2.2. Using Ncurses

To create a region, follow these steps:

  1. Select Actions->Create->Region.

  2. Select the LVM Region Manager. Activate Next.

  3. Select the freespace region from the container you created earlier in Chapter 8. Verify that the region is named lvm/Sample Container/Freespace.

  4. Scroll to the Name field, and press spacebar.

  5. Type Sample Region at the "::" prompt. Press Enter.

  6. Scroll to the size field, and press spacebar.

  7. Type 1000MB at the "::" prompt. Press Enter.

  2. Activate the Create Region menu item.

  3. Continue beginning with step 4 of the Ncurses instructions.

9.2.3. Using the CLI

Create regions with the Create command. Arguments to the Create command are the following: keyword Region, the name of the region manager to use, the region managers options, and the objects to consume. The form of this command is:

Create:region, LvmRegMgr={name="Sample Region", size=1000MB},
"lvm/Sample Container/Freespace"

The LVM Region Manager supports many options for creating regions. To see the available options for creating regions and containers, use the following Query:
