lotus miner 元数据 删除 重建

本文主要是介绍lotus miner 元数据 删除 重建，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

主网 lotus-miner backup

Backup and restore

测试网模拟lotus-miner元数据损坏，重建

# echo $LOTUS_MINER_PATH
/raid0/calibnet/miner

删除miner目录下所有内容

# rm -rf /raid0/calibnet/miner/*

指定原来的矿工号重新初始化

lotus-miner init --no-local-storage --actor=t矿工号 --owner=t3钱包 --sector-size=32GiB

• 运行miner

nohup lotus-miner run >> /var/log/calibnet/miner.log 2>&1 &

lotus-miner info

• 修改lotus-miner配置文件config.toml 和storage.json

lotus-miner stop

# cat $LOTUS_MINER_PATH/config.toml | grep -Ev '^$|#'
[API]ListenAddress = "/ip4/192.168.1.92/tcp/2345/http"RemoteListenAddress = "192.168.1.92:2345"
[Backup]
[Libp2p]
[Pubsub]
[Subsystems]
[Dealmaking][Dealmaking.RetrievalPricing][Dealmaking.RetrievalPricing.Default][Dealmaking.RetrievalPricing.External]
[Sealing]BatchPreCommits = falseAggregateCommits = false
[Storage]AllowAddPiece = falseAllowPreCommit1 = falseAllowPreCommit2 = falseAllowCommit = falseAllowUnseal = false
[Fees][Fees.MaxPreCommitBatchGasFee][Fees.MaxCommitBatchGasFee]
[Addresses]
[DAGStore]

• 存储目录重新init会报错

# lotus-miner storage attach --init --store /store/
ERROR: path is already initialized

• 存储目录可以直接修改

# cat $LOTUS_MINER_PATH/storage.json
{"StoragePaths": null
}

# cat $LOTUS_MINER_PATH/storage.json
{"StoragePaths": [{"Path": "/store"}]
}

lotus-miner storage list

看不到扇区列表

lotus-miner sectors list

环境变量配置miner API

lotus-miner auth api-info --perm admin

运行 lotus-worker

nohup lotus-worker run >> /var/log/calibnet/worker.log 2>&1 &

修改LevelDB

• pledge 扇区编号ID会从0开始，需要修改nextid
• 查看扇区的最新ID，最新扇区ID为26

lotus-miner proving deadlines
lotus-miner proving deadline <Index>
lotus-miner proving check <Index>

# mkdir leveldb_nextid
# cd leveldb_nextid/
# go mod init leveldb_nextid
# vim leveldb_nextid.go

• 停止mienr

lotus-miner stop

cat leveldb_nextid.go

package main
import ("fmt""log""github.com/syndtr/goleveldb/leveldb""encoding/binary"
)func main(){// 打开数据库db, err := leveldb.OpenFile("/raid0/calibnet/miner/datastore/metadata", nil)if err != nil {  log.Fatal(err)  }  // 关闭数据库defer db.Close()// 遍历数据fmt.Println("遍历数据")iter := db.NewIterator(nil, nil)  for iter.Next() {  fmt.Printf("key:%s, value:%s\n", iter.Key(), iter.Value())  //fmt.Printf("key:%s \n", iter.Key())  }  iter.Release()  buf := make([]byte, binary.MaxVarintLen64)size := binary.PutUvarint(buf, 26)fmt.Print(size)fmt.Printf("%v \n", buf[:size])db.Put([]byte("/storage/nextid"), buf[:size], nil) nextid, _ := db.Get([]byte("/storage/nextid"), nil)  fmt.Printf("读取单条数据 nextid:  %v\n", nextid)}

go get github.com/syndtr/goleveldb/leveldb

# go run leveldb_nextid.go

1[26] 
读取单条数据 nextid:  [26]

扇区ID 从27开始

# lotus-miner sectors pledge
Created CC sector:  27

# lotus-miner sectors list
ID  State    OnChain  Active  Expiration  Deals
27  Packing  NO       NO      n/a         CC

修改nextid 大的数字

• nextid 修改为1600

         buf := make([]byte, binary.MaxVarintLen64)size := binary.PutUvarint(buf, 1600)fmt.Print(size)fmt.Printf("%v \n", buf[:size])db.Put([]byte("/storage/nextid"), buf[:size], nil) 

读取单条数据 nextid:  [192 12]

# lotus-miner sectors pledge
Created CC sector:  1601

参考

1. /storage/nextid
2. leveldb 修改
3. 原语云
4. goleveldb
5. Go语言中调用levelDB
