[Storage Provider Bounty Issue] Write a document on how to recover lost sector numbers in leveldb

dayou5168 commented 3 years ago

1. Proposed issue:

When the miner node fails and the miner is recovering, some sectors are generated after the backup data, the recovered miner node will lose this part of the sector number and need to manually modify the leveldb to recover the missing sector number

2. Why is this issue important?

If the lost sector number cannot be recovered, the miner's sector number will be overwritten and a penalty will be applied as a result

3. Tasks

[ ] what's the risk
[ ] how to manually recover the sector number in leveldb
[ ] how to find the missing sectors number? maybe the blockchain browser or request from api. describe the process.

4. Additional Context

no

The Filecoin project will create a sector repair tool to reduce the penalty of sector loss and damage and requiring sector termination, and repair problems during sector maintenance. Let's looking forward to it .
