Architecture
Manager
Manages is the top-level piece of the storage system gluing all the other pieces together. It also implements scheduling logic.
package paths
This package implements the sector storage subsystem. Fundamentally the storage
is divided into paths, each path has it's UUID, and stores a set of sector
'files'. There are currently 5 types of sector files - unsealed, sealed, cache, update and update-cache.
Paths can be shared between nodes by sharing the underlying filesystem.
paths.Local
The Local store implements SectorProvider for paths mounted in the local filesystem. Paths can be shared between nodes, and support shared filesystems such as NFS.
stores.Local implements all native filesystem-related operations
paths.Remote
The Remote store extends Local store, handles fetching sector files into a local store if needed, and handles removing sectors from non-local stores.
paths.Index
The Index is a singleton holding metadata about storage paths, and a mapping of sector files to paths
LocalWorker
LocalWorker implements the Worker interface with ffiwrapper.Sealer and a store.Store instance
