In RHEL 8, which package is necessary for managing storage with Stratis?

In RHEL 8, the key package required for managing storage with Stratis is stratisd. This is the daemon that facilitates the Stratis storage management operations, allowing users to create and manage storage pools, file systems, and snapshots. Stratis is designed to provide a simplified storage management experience, functioning similarly to other modern storage systems.

The stratis-cli package, while related to Stratis, is a command-line interface tool that interacts with stratisd to perform operations. However, without stratisd running as the backend service, the CLI tool does not have a daemon to communicate with for executing storage management tasks.

The package lvm2 is associated with Logical Volume Management, which serves a different purpose in managing hard drives and filesystems. While both LVM and Stratis are used for storage management, they are separate technologies with different functionalities.

The option openstack pertains to a cloud computing platform and is not relevant to the management of storage using Stratis. Thus, stratisd is the essential package that operates as the core of the Stratis storage management framework in RHEL 8.
