Modifying a storage group
To modify a storage group via the user interface, complete the following steps
- In the navigation menu, click Local Storage to expand the menu, then click Storage Groups.
- 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.
- Click Edit.
- For Storage Optimization, select a Compression Type from the drop-down list as needed:
- Fast— Results in shorter backup time, but with less space savings.
- Best — Provides the highest space savings, but with a longer backup time.
- Optionally, configure a Quota by entering an amount and setting the unit (GiB or TiB). If no value is set, the quota will be unlimited. If a quota is currently set, you may increase or decrease the quota value (provided the decreased quota is not less than the current used capacity on the storage group). Once a quota is set, it can be reset to the default value of unlimited.
|
|
NOTE: Quotas define the limit for physical capacity usage. Once reached, data ingests are not allowed until space is recovered through savepoint expiration and cleaner operations. |
- You can modify the following Encryption settings:
|
|
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. |
- Passphrase—Enter the 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—Next to Encryption, select or clear as needed.
- 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.
- Click Update.
To modify a storage group via the CLI, complete the following steps
-
- Access the QoreStor CLI. Refer to Using the QoreStor command line for more information.
- Modify your storage group using the commands below. Refer to the QoreStor Command Line Reference Guide for more information.
storage_group --show [--name <name>] [--verbose]
storage_group --update --name <name> [--compression_mode <fast|best>] [--quota <Quota value in GiB or TiB>]
storage_group --encryption --name <name> [--set <ON | OFF>] [--mode <static|internal> <--interval <7 days to 70 years>]
storage_group --setpassphrase --name <name>
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.
- In the navigation menu, click Local Storage to expand the menu, then click Storage Groups.
- 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.
- Click Delete.
|
|
NOTE: You cannot delete the DefaultGroup storage group. |
- When prompted to confirm, click Delete.
Deleting a storage group from the CLI
- Access the QoreStor CLI. Refer to Using the QoreStor command line for more information.
- 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.
- In the navigation menu, click Local Storage to expand the menu, then click Performance Tier.
- Click Add Performance Tier.
- Enter the mount path for the performance tier volume.
- 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.
- Click Add.
When a performance tier is added, QoreStor will also create the corresponding storage group "PerformanceTier" mapped to the performance tier storage.
- 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. |
- 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.
-
- Access the QoreStor CLI. Refer to Using the QoreStor command line for more information.
- 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
- 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. |
