Volumes

Volumes provide a way to keep data even after a workload (like a Notebook or ModelService) is restarted or deleted. They also allow different workloads to share data. Volumes are usually connected to host paths and managed by storage providers through a StorageClass.

When setting up a workload that needs persistent storage, you can choose the StorageClass and specify the volume size in the configuration. LLMOS includes built-in StorageClasses like local-path or llmos-ceph-block, which let you create volumes on demand.

note

1. The local-path StorageClass doesn't support resizing volumes or assigning them to specific nodes.
2. To use the llmos-ceph-block or llmos-ceph-filesystem StorageClasses, you must first enable Ceph storage in your cluster.

info

When you delete a workload, its volumes won't be deleted automatically to prevent data loss. You'll need to delete them manually on the volumes page, or you can reuse them by choosing Use Existing Volume in the workload's volume settings.
