sector-storage

a concrete implementation of the specs-storage interface

The sector-storage project provides a implementation-nonspecific reference implementation of the specs-storage interface.

Please report your issues with regards to sector-storage at the lotus issue tracker

Architecture

`Manager`

Manages is the top-level piece of the storage system gluing all the other pieces together. It also implements scheduling logic.

`package stores`

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 3 types of sector files - unsealed, sealed, and cache.

Paths can be shared between nodes by sharing the underlying filesystem.

`stores.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

`stores.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.

`stores.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
