Create API keys and use CubeCOS's RESTful API to access Ceph storage programmatically.

Add a new hard disk to a CubeCOS storage pool, either individually or all at once, and verify the cluster provisions OSDs onto it.

Change the Ceph data replication factor for a CubeCOS storage pool to adjust the balance between fault tolerance and available capacity.

The SSD caching tier can be tailored to different workloads by adjusting the cache ratio and behavior.

Check the status of Ceph OSDs in a CubeCOS storage cluster, including power-on time, usage, and disk health details.

Configure external SAN and NAS storage integration in CubeCOS to host VM disks and images, optimize internal SDS usage, and support hybrid storage architectures.

Create a public Swift object storage container, upload files to it through the dashboard, and access objects through the Swift API.

Create NFS or CIFS network shares at the tenant or project level for use in virtual machines.

Create a full or incremental backup of a volume for long-term protection and disaster recovery.

Create a volume mirror for disaster recovery or replication requirements.

Create a point-in-time snapshot of an existing volume for fast rollback, testing, or short-term recovery.

Permanently remove a failed hard disk from your storage pool using the prepare_disk command without physical removal. Safely wipe partition tables and decommission hardware via software.

Identify a failed physical disk in a CubeCOS storage pool and safely remove it from the cluster using safe or force mode.

Learn how to transfer a volume to another project in CubeCOS and confirm storage health.

This guide covers how to utilize external storage in CubeCOS, including attaching volumes, verifying connections, and troubleshooting multipath storage across FC, iSCSI, and NFS.
