storaged

If available on the system, Cockpit uses +storaged+ to configure and monitor storage, disks, mounts etc. on the system. This functionality is present in the Cockpit storaged package.

The +storaged+ project is originally based on a project called +udisks+ and added support for many more features such as LVM, iSCSI, Multipath, and BTRFS. The same tools and backwards compatible API are available between +storaged+ and +udisks+ the projects. Cockpit can use +udisks+ but disables many of it’s storage related features, including updating +/etc/fstab+ and +/etc/crypttab+ for stability reasons.

For non root users, storaged controls access to its APIs via Policy Kit and a user logged into Cockpit will have the same permissions as they do from the command line.

To perform similar tasks from the command line, use the +storagedctl+ command:

To perform LVM tasks, you may use the various LVM commands, such as +vgcreate+, +lvresize+ and so on. Cockpit will detect such changes made at the command line.

Cockpit recognizes devices with multiple paths and can start the +multipathd+ service in case it is not running. On the command line, you can control multipath features with the +mpathconf+, +multipathd+, and +multipath+ commands.

To manage iSCSI initiators from the command line, you can use +iscsiadm+ and related tools.
