# Lotus-Provider Sealer
|
||
|
|
|
||
|
|
## Overview
|
||
|
|
|
||
|
|
The lotus-provider sealer is a collection of harmony tasks and a common poller
|
||
|
|
which implement the sealing functionality of the Filecoin protocol.
|
||
|
|
|
||
|
|
## Pipeline Tasks
|
||
|
|
|
||
|
|
* SDR pipeline
|
||
|
|
* `SDR` - Generate SDR layers
|
||
|
|
* `SDRTrees` - Generate tree files (TreeD, TreeR, TreeC)
|
||
|
|
* `PreCommitSubmit` - Submit precommit message to the network
|
||
|
|
* `PoRep` - Generate PoRep proof
|
||
|
|
* `CommitSubmit` - Submit commit message to the network
|
||
|

# Poller
|
||
|
|
|
||
|
|
The poller is a background process running on every node which runs any of the
|
||
|
|
SDR pipeline tasks. It periodically checks the state of sectors in the SDR pipeline
|
||
|
|
and schedules any tasks to run which will move the sector along the pipeline.
|
||
|
|
|
||
|
|
# Error Handling
|
||
|
|
|
||
|
|
* Pipeline tasks are expected to always finish successfully as harmonytask tasks.
|
||
|
|
If a sealing task encounters an error, it should mark the sector pipeline entry
|
||
|
|
as failed and exit without erroring. The poller will then figure out a recovery
|
||
|
|
strategy for the sector.
