Deleting a storage group

Before you can delete a storage group, you must first delete the containers in the storage group. See Deleting a container for more information.

Deleting a storage group from the GUI

To delete a storage group, complete the following steps.

  1. In the navigation menu, click Local Storage to expand the menu, then click Storage Groups.
  2. Find the desired storage group from the displayed list. Click the (ellipsis icon) in the upper-right corner of the storage group's information pane.
  3. Click Delete.

    NOTE: You cannot delete the DefaultGroup storage group.

  4. When prompted to confirm, click Delete.

Deleting a storage group from the CLI

    Access the QoreStor CLI. Refer to Accessing the CLI commands for more information.
  1. Delete your storage group using the command below. Refer to the QoreStor Command Line Reference Guide for more information. 
    storage_group --delete --name <name>

Configuring a Performance Tier

Before configuring a performance tier, ensure that you have reviewed the requirements and limitations below.

  • Only one volume can be mapped to a performance tier.
  • Your performance tier volume must be mapped to high-performance storage.
  • Your performance tier volume must be mapped to an XFS file system.
  • An existing QoreStor repository may not be mapped to a performance tier.
  • Once a performance tier has been created, the storage path cannot be changed.
  • Only one performance tier can be added to QoreStor.
  • Currently, it is not possible to delete the performance tier.
  • The mount location for the high-performance storage must be added to your QoreStor system's file systems table (fstab) to mount the storage automatically when the server reboots.

    Add mount location to /etc/fastab using the noatime and drsync mount options

    echo '<storage path> /perf01 xfs defaults,noatime,dirsync 0 0' >> /etc/fstab

Adding a performance tier

Adding a performance tier can be accomplished through the QoreStor UI or via the performance_tier command in the QoreStor CLI. Refer to the QoreStor Command Line Reference Guide for more information on the performance_tier command.

To add a performance tier

Before adding a performance tier, ensure that the storage is mounted to the QoreStor server as an XFS filesystem. Refer to Guidelines for configuring additional storage for additional guidelines and requirements.

  1. In the navigation menu, click Local Storage to expand the menu, then click Performance Tier.
  2. Click Add Performance Tier.
  3. Enter the mount path for the performance tier volume.
  4. Optionally, click Test to ensure this storage meets the performance requirements. You will be prompted that the test can take several minutes, click Confirm to continue.
  5. Click Add.

    When a performance tier is added, QoreStor will also create the corresponding storage group "PerformanceTier" mapped to the performance tier storage.

  6. A warning will be displayed notifying you that a service restart may be required. Click Confirm to continue.

    NOTE: QoreStor services will be restarted. You will need to log into the UI once the restart is complete.

  7. Once the performance tier is created, you can enable encryption. Refer to Editing a performance tier.

 

Adding a performance tier through the command line

To add a performance tier, complete the following steps.

  1. Access the QoreStor CLI. Refer to Accessing the CLI commands for more information.
  2. Add a performance tier using the command 
    performance_tier --add --path <enclosure filesystem dir> [--compression_mode <fast|best>] [--quota <Quota value in GiB or TiB>}

    Refer to the QoreStor Command LIne Reference Guide for more information

  3. To apply encryption to the data in this performance tier, use the command:
    performance_tier --encryption [--set <ON | OFF>] [--mode <static|internal> <--interval <7 days to 70 years>]

    For more information, refer to the QoreStor Command Line Reference Guide.

    NOTE: Due to export regulations, the encryption at rest feature is not available in certain markets, and, therefore, may not be available in your locale. For more information about recommended guidelines for encryption, see Understanding Encryption at Rest

    NOTE: It is mandatory to define a passphrase to enable encryption. If the passphrase is compromised or lost, the administrator should change it immediately so that the content encryption keys do not become vulnerable.

    NOTE: After encryption is enabled, all of the data that is backed up is encrypted and is kept encrypted until it is expired and cleaned by the system cleaner. Note that encryption is an irreversible process.

 

Editing a performance tier

To modify a performance tier via the user interface, complete the following steps

  1. In the navigation menu, click Local Storage to expand the menu, then click Performance Tier
  2. Click Edit Performance Tier.
  3. On the Edit Performance Tier page, select or modify the options below, as appropriate:
    • Unlimited Quota— This option is selected by default. To set a quota, de-select this option and enter a numeric value (greater than 100) in the Quota field. Select the value format (either GiB or TiB). Refer to Quotas for more information. Once a quota is set, it can be reset to the default value of unlimited.
    • Encryption— Select this option to enable encryption on the performance tier.
    • Old Passphrase—Enter the current passphrase you want to change.
    • New Passphrase—Enter the new passphrase to be used to encrypt content encryption keys. (The passphrase string can take up to 255 characters. And, alphanumeric and special characters can be entered as part of the passphrase string.)
    • Confirm Passphrase—Re-enter the encryption passphrase.
    • Encryption Mode— Select the mode of key lifecycle management from one of the following options:
      • Static— A global, fixed key is used to encrypt all data.
      • Internal— Content encryption keys are generated and rotated on a specified period of days.
    • Key Rotation— Displays the number of key rotation interval days as N/A, or the number that was set for Internal Encryption Mode. If you selected Internal as the mode of key management, select the number of days for key rotation when a new key is to be generated. This option is available only for Internal encryption mode.

      NOTE: After encryption is enabled, all of the data that is backed up is encrypted and is kept encrypted until it is expired and cleaned by the system cleaner. Encryption is an irreversible process.

  4. Click Update.

To modify a performance tier via the CLI, complete the following steps

  1. Access the QoreStor CLI. Refer to Accessing the CLI commands for more information.
  2. Modify your performance tier using the command below. Refer to the QoreStor Command Line Reference Guide for more information. 
    performance_tier --update  [--compression_mode <fast|best>] [--quota <Quota value in GiB or TiB>]
    performance_tier --encryption [--set <ON | OFF>] [--mode < static | internal >] [--interval <7 days to 70 years>]
