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
Manages is the top-level piece of the storage system gluing all the other pieces together. It also implements scheduling logic.
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.
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
The Remote store extends Local store, handles fetching sector files into a local store if needed, and handles removing sectors from non-local stores.
The Index is a singleton holding metadata about storage paths, and a mapping of sector files to paths
LocalWorker implements the Worker interface with ffiwrapper.Sealer and a store.Store instance
