[Blockchain 네트워크 구성] Hyperledger Fabric v1.2 Private Data 저장 오류 해결

Private Data 저장 및 조회에 관련된 테스트 내용은 Hyperledger Fabric v1.2에서 Private Data 저장 및 조회 글을 참고하시기 바랍니다.

오류 발생

honeybee 네트워크에서 Private Data를 저장하기 위해 테스트하는 도중, invoke 명령에서 다음과 같은 오류가 발생하였습니다.

명령은 org1의 cli 컨테이너에서 org5의 peer0을 기준으로 실행하였습니다.

Error: endorsement failure during invoke. chaincode result: <nil>

총 6개의 org(org1 ~ org6) 중 org4번과 org6번에서만 해당 오류가 발생하였고, 나머지 org에서는 정상적으로 invoke 및 query가 가능하였습니다...

로그 확인

위와 같은 오류를 해결하기 위해, orderer 컨테이너와 peer0.org5 컨테이너의 로그를 확인해 보겠습니다.

orderer.org5.honeybee.com 컨테이너 로그 확인

2018-07-09 23:47:50.006 UTC [orderer/common/broadcast] Handle -> WARN 057 Error reading from <org1 호스트의 IP 주소>:41848: rpc error: code = Canceled desc = context canceled
===================================================================================

오류로 인해 명령이 정상적으로 수행되지 않았기 때문에 출력되는 로그인 것 같습니다.

peer0.org5.honeybee.com 컨테이너 로그 확인

다음으로 peer0.org5.honeybee.com 컨테이너의 로그를 확인해보니 다음과 같은 오류가 출력되었습니다.

오류 해결

peer0.org5.honeybee.com 컨테이너에서 출력된 로그를 검색해보니, hyperledger/fabric-ccenv 이미지가 없어서 발생한 오류였습니다.

실제로 각 호스트에서 docker image ls 명령을 통해 이미지를 확인해보니 org4와 org6의 호스트에서만 해당 버전에 맞는 hyperledger/fabric-ccenv 이미지가 존재하지 않았습니다.

따라서 org4와 org6에서 hyperledger/fabric-ccenv:1.2.0, hyperledger/fabric-ccenv:latest 이미지를 다운로드하고 네트워크를 다시 시작합니다. 기존에 hyperledger/fabric-ccenv:latest 이미지가 존재하고 있었다면, 버전이 안맞을 수도 있으니 해당 이미지를 제거하고 다시 다운로드합니다.

# 기존에 hyperledger/fabric-ccenv:latest 이미지가 있었던 경우, 해당 이미지 제거 후 재다운로드 필요
docker image rm hyperledger/fabric-ccenv:latest

docker image pull hyperledger/fabric-ccenv:1.2.0
docker image pull hyperledger/fabric-ccenv:latest

깔끔하게 모든 docker 이미지를 제거하고 다시 다운로드해도 됩니다.

docker image rm -f $(docker image ls -aq)

cd /opt/gopath/src/github.com/hyperledger
rm -rf fabric-samples
curl -sSL http://bit.ly/2ysbOFE | bash -s 1.2.0

네트워크를 다시 실행하면서 볼륨 데이터를 모두 지우기 때문에 기존에 조인했던 피어들이 모두 사라지게 됩니다. 따라서, peer0.org5, peer1.org5에 대한 조인 명령과 체인코드 install 명령을 다시 수행한 뒤 체인코드를 업그레이드하고 invoke 명령을 수행해주어야 합니다.
