Storage Management Installation and Overview

The Storage application enables Cockpit administrators to perform routine storage management tasks on a host system. Before you can access the Storage page in the web console, the cockpit storage application must be installed, for example:

sudo dnf install cockpit-storaged

Note:

For more information about adding applications to the Cockpit web console, see Install and Manage Add-on Applications.

Upon accessing the Storage page, administrators can easily monitor and manage all things to do with disk storage. For example, at the top of the page, two line graphs appear depicting the disk's read and write performance and following the line graphs is the disk's local file system information. In addition, configuration properties are easily accessible for adding or changing RAID devices, volume groups, iSCSI devices, and storage drives. Further down the page, a summary appears in the Log section displaying real-time storage events generated by the host system.

For further details about the storage management functionality available from the Cockpit web console, see the following table:

Note:

Administrator privileges are required to view and use the configurable storage properties. Read-only properties for viewing storage information are accessible for users with limited access.

Filesystems	The Filesystem table on the main Storage page identifies the physical partitions and logical volumes configured on a host storage device. Clicking an entry in the table displays configuration details about the storage device and properties for managing its physical partitions or logical volumes.
NFS mounts	When available, the NFS mounts table on the main Storage page identifies the NFS mount connections configured on the host system. Clicking the entry in the NFS mount table displays connection information and configurable properties for that NFS mount. When NFS mounts are available but not configured on the host, the table displays a message indicating "No NFS Mounts are set up". Clicking the plus [+] icon displays a dialog for configuring an NFS mount connection.
Storage Logs	The Storage Log section on the main Storage page identifies storage related events for observation. Clicking a log entry displays more information about the selected storage event.
Devices	The Devices section on the main Storage page identifies RAID devices or logical volume groups configured on the host system. Clicking the Devices menu displays options to create a RAID device or logical volume (LVM) group.
Drives	The Drives section on the main Storage page, identifies the block storage type drives that are configured on the host system. Clicking a storage drive entry in this section displays information about that storage drive's configuration, as well as configurable properties to manage its storage partitions.
iSCSI target	When available, the iSCSI target section on the main Storage page identifies the iSCSI server connections configured on the host system. Clicking the edit icon displays properties for changing a configured connection. Clicking the Plus [+] icon displays properties for configuring a new iSCSI server connection. For instances where iSCSI targets aren't configured on the host, a message appears indicating "No iSCSI targets" are set up.
Other Devices	When available, the Other Devices section on the main Storage page identifies attached data storage host configurations. For example, attached OCI block data volume configurations appear in this section. Clicking on a block data volume entry in this section displays the file directory path, the storage capacity size and the data volume's contents. Configurable properties for managing the block storage data volume content are also available.

Note:

The host system storage configuration appearing on the Storage page reflects the storage devices discovered by the cockpit-storaged application. For specific details about the cockpit-storaged application, see the Cockpit project website ( https://cockpit-project.org/guide/latest/feature-storaged).
