Managing Storage Pools in Catalogic vStor

To view information about each storage pool, use vstor pool show CLI command.

Creating a Storage Pool

To create a storage pool manually:

  • Ensure unused disks are available.

  • Use the vstor pool create command.

  • Specify a display name and disk list.

  • Select options like enabling/disabling compression, deduplication, and synchronous writes.

You can also update the settings later using:

vstor pool update

Note. Disabling synchronous writes risks data loss during abrupt shutdowns. Disabling this option is not recommended.

You can also create a storage pool using the vStor Web Interface by navigating to the Storage tab, clicking Create New Pool, and specifying its details:

Now, select a pool, which specifies the redundancy of the pool:

  • raid0: Assumes external disk redundancy.

  • raid5: Creates RAID5 groups for redundancy.

  • raid6: Forms RAID6 groups for enhanced redundancy.

Expanding a Storage Pool

Before expanding a pool, ensure one or more unused disks are available.

To expand a storage pool from the vStor Web Interface, navigate to the Disks section of the pool. select Add Disk -> Expand Pool and select the disk you want to add:

To expand a storage pool from the CLI, use:

vstor pool expand

Disabling a Storage Pool

To temporarily make a storage pool inaccessible, such as for maintenance, you can disable it. When a pool is disabled, you can’t change its volumes. The only actions you can take are to edit the pool’s settings, delete it, or re-enable it.

To disable a pool from the CLI, run:

vstor pool offline --id <id>

To disable a pool from the vStor Web Interface, simply click on its current status (e.g., Online) and confirm that you want to change the status.
