Chapter 20. Configuring thin logical volumes using the web console

Procedure

1. Log in to the RHEL 9 web console.
2. Click Storage.
3. Click the volume group in which you want to create thin volumes.
4. Click Create new Logical Volume.
5. In the Name field, enter a name for the new pool of thin volumes without spaces.
6. In the Purpose drop down menu, select Pool for thin-provisioned volumes. This configuration enables you to create the thin volume.

7. Define the size of the pool of thin volumes. Consider:

   • How many thin volumes you will need in this pool?
   • What is the expected size of each thin volume?

   You do not have to use the whole space. If necessary, you can grow the pool later.

8. Click Create.

   The pool for thin volumes has been created and you can add thin volumes.

Procedure

1. Log in to the RHEL 9 web console.
2. Click Storage.
3. Click the volume group in which you want to create thin volumes.
4. Click the desired pool.
5. Click Create Thin Volume.
6. In the Create Thin Volume dialog box, enter a name for the thin volume without spaces.
7. Define the size of the thin volume.
8. Click Create.

Procedure

1. Log in to the RHEL 9 web console.
2. Click Storage.
3. In the Devices section, click the volume group in which the logical volume is placed.

4. In the Logical volumes section, click Format.

   

5. In the Name field, enter a name for the file system.

6. In the Type drop down menu, select a file system:

   • XFS file system supports large logical volumes, switching physical drives online without outage, and growing an existing file system. Leave this file system selected if you do not have a different strong preference.

     XFS does not support reducing the size of a volume formatted with an XFS file system

   • ext4 file system supports:

     • Logical volumes
     • Switching physical drives online without outage
     • Growing a file system
     • Shrinking a file system

   You can also select a version with the LUKS (Linux Unified Key Setup) encryption, which allows you to encrypt the volume with a passphrase.

7. Select the Overwrite option:

   • Don’t overwrite existing data — the RHEL web console rewrites only the disk header. Advantage of this option is speed of formatting.
   • Overwrite existing data with zeros — the RHEL web console rewrites the whole disk with zeros. This option is slower because the program have to go through the whole disk. Use this option if the disk includes any data and you need to overwrite it.

8. In the Mount Point field, add the mount path.

   

9. Click Format.

   Formatting can take several minutes depending on the volume size and which formatting options are selected.

   After the formatting has completed successfully, you can see the details of the formatted logical volume on the Filesystem tab.

   

10. To use the logical volume, click Mount.
