Getting permission denied error when trying to restore fabric network

Docker swarm

Hyperledger fabric v1.4.4

I'm trying to restore the blockchain network with all the previous data. So what I did that I have created a backup of /var/hyperledger/production/node_type directory for every node. And then using these directory like below in docker-compose.yaml file

Lets assume I have created a backup of orderer1 node in myproject/networks/orderer1 directory then under volume section I'm doing something like myproject/networks/orderer1/production:/var/hyperledger/production.

compose-file before network restoration

volumes:
  - orderer1.example.com:/var/hyperledger/production/orderer:rw

compose file for restoring network

volumes:
  /home/delta/GoWorkspace/src/github.com/testchain/bchain_network/orderer1/orderer:/var/hyperledger/production/orderer:rw

But when I'm trying to start the network it gives an error

Orderer node

panic: Error opening leveldb: open /var/hyperledger/production/orderer/index/LOCK: permission denied

The link that I'm following for network restoration is https://medium.com/@jariarud/hyperledger-fabric-backup-and-restore-3263561e259e

Please help.

Solution

  • You do not need to manually map the location of the volume like below and remove :rw

    volumes:
  /home/delta/GoWorkspace/src/github.com/testchain/bchain_network/orderer1/orderer:/var/hyperledger/production/orderer

    Just leave as it is docker will take care of that like below

    volumes:
  - orderer1.example.com:/var/hyperledger/production/orderer
