Even if we can use raw mode, do NOT use raw mode on disks. Ceph bluestore disks can sometimes appear as though they have "phantom" Atari (AHDI) partitions created on them when they don't in reality. This is due to a series of bugs in the Linux kernel when it is built with Atari support enabled. This behavior does not appear for raw mode OSDs on partitions, and we need the raw mode to create partition-based OSDs. We cannot merely skip creating OSDs on "phantom" partitions due to a bug in `ceph-volume raw inventory` which reports only the phantom partitions (and malformed OSD info) when they exist and ignores the original (correct) OSDs created on the raw disk.

Rook
Rook is an open source cloud-native storage orchestrator, providing the platform, framework, and support for a diverse set of storage solutions to natively integrate with cloud-native environments.
Rook turns storage software into self-managing, self-scaling, and self-healing storage services. It does this by automating deployment, bootstrapping, configuration, provisioning, scaling, upgrading, migration, disaster recovery, monitoring, and resource management. Rook uses the facilities provided by the underlying cloud-native container management, scheduling and orchestration platform to perform its duties.
Rook integrates deeply into cloud native environments leveraging extension points and providing a seamless experience for scheduling, lifecycle management, resource management, security, monitoring, and user experience.
For more details about the status of storage solutions currently supported by Rook, please refer to the project status section of the Rook repository. We plan to continue adding support for other storage systems and environments based on community demand and engagement in future releases.
Quick Start Guides
Starting Rook in your cluster is as simple as a few kubectl commands depending on the storage provider.
See our Quickstart guide list for the detailed instructions for each storage provider.
