Managing containers
In QoreStor, data is stored in containers, which are stored in storage groups. Some containers function like a shared file system. These types of containers can be assigned a specific connection type, for example, NFS/CIFS or RDA (including both OST and RDS clients). These containers are then accessed via NFS, CIFS, and RDA protocols.
In QoreStor you can manage your storage groups and data containers, including viewing storage groups and containers, creating new storage groups and containers, modifying or deleting them, moving data into containers, and viewing current statistics. Management for containers can be done either through the GUI or the command line.

NOTE: If only the DefaultGroup storage group exists on your system, all containers you create are automatically added to that group. You can create custom storage groups, and then when you create a container, you can specify that it be added to the custom storage group. For more information about storage groups, see the topic, “Managing Storage Groups.” |
Viewing containers
You can easily view a list of containers in your QoreStor instance on the Storage Containers page, or by using the container command in the QoreStor CLI.
Viewing containers in the GUI
- In the navigation menu, click Containers. The Containers page is displayed.
- You can view the following columns of information about the containers.
- Container—The name of the container.
- Path —The path for the container.
- Marker —The marker type that supports your Data Management Application (DMA).
- Connection — The connection type/access protocol for the container:
- NFS
- CIFS
- RDA
- OST
- Cloud Tiering Policy— The status of whether the container is connected to a cloud container. If a cloud container link is not configured, Enable Cloud Tiering Policy will be displayed.
- Ellipsis icon
— Provides additional options as listed below:
- Details
- Enable Cloud Tiering Policy
- Edit
- Delete
Viewing containers via the CLI
To view the list of containers, follow these steps.
- Access the QoreStor CLI. Refer to Using the QoreStor command line for more information.
- To view the containers on this QoreStor instance, use the command
container --show [--name <name>] [--verbose]
Refer to the QoreStor Command Line Reference Guide for more information.
Viewing container statistics
To display container statistics for a selected container, complete the following steps.
- In the navigation menu, click Containers. The Containers page is displayed.
- In the list of containers, find the container for which you want to view statistics, and then click the
- Click Details.
- The Container details page contains the following sections:
- In the Active Files, Active Bytes, and Throughput charts, you can view current statistics for the container.
The Active Files chart displays the number of active files ingested based on time (in minutes), and the Active Bytes displays the number of active bytes ingested based on time (in minutes).
The Throughput chart displays the number of read data in Mebibytes/per second (MiB/s) based on time (in minutes), and the number of write data in MiB/s based on time (in minutes).
NOTE: The values in the Active Files, Active Bytes, and Throughput charts refresh automatically every 15 seconds.
- In the Connection pane, you can view information about the configured connection type for the selected container. The type of information displayed can be different depending on the connection type. For example, for an RDS container, the following information is displayed:
- Type
- Enabled
- Status
- Capacity
- In the Inbound Stats and Outbound Stats panes, you can view detailed information on the inbound throughput, and outbound throughput.
- The Client Stats pane lists ingest and network information.
- In the Active Files, Active Bytes, and Throughput charts, you can view current statistics for the container.
Displaying container statistics by using the CLI
An alternate method for viewing container statistics is by using the QoreStor CLI command: stats --container --name <container name>
This command shows the following information:
- Container Name (name of the container)
- Container ID (ID associated with container)
- Total Inodes (total number of data structures in container)
- Read Throughput (read throughput rate in Mebibytes or MiB/s for container)
- Write Throughput (write throughput rate in MiB/s for container)
- Current Files (current number of files in container)
- Current Bytes (current number of ingested bytes in container)
- Cleaner Status (current space reclamation process status for the selected container)
