1，lotus 扇区报错 PreCommitFailed

# lotus version
Daemon:  0.9.0+git.8f35a5c0.dirty+api0.16.0
Local: lotus version 0.9.0+git.8f35a5c0.dirty

• 查看扇区PreCommitFailed

# lotus-miner sectors list
94   PreCommitFailed

lotus-miner storage find 94

lotus-miner sectors status --log --on-chain-info 94

• 扇区已经完成PreCommit2 ，PreCommitting报错
• 参考：扇区状态

2，扇区重新运行PreCommitting

lotus-miner sectors update-state --really-do-it 94 PreCommitting

# lotus-miner sectors status --log --on-chain-info 94
[event;sealing.SectorForceState]	{"User":{"State":"PreCommitting"}}

删除扇区

lotus-miner sectors remove --really-do-it 3

3，CommitFailed

# lotus-miner sectors list | grep CommitFailed
1566  CommitFailed         YES      NO      1771845 (in 1 year 24 weeks)  CC

lotus-miner sectors update-state --really-do-it 1566 Committing

# lotus-miner sectors list | grep 1566
1566  FinalizeSector       YES      NO      1771845 (in 1 year 24 weeks)  CC
