Hyperledger Composer下docker重启后chaincode无法启动记录

• 背景是磁盘空间因为docker容器日志满，环境是使用composer的区块链网络。
• 正确清理姿势（比如我这个）

到 /app/install/docker/lib/docker/containers/ 下面的那个容器文件夹内执行  
cat /dev/null > *-json.log

• lsof |grep deleted 查看删除文件是否存在引用（如果直接删的日志，是不会减少空间的，需要删除引用）

• 由于一开始没有正确清理，直接删除了。空间没有恢复。果断重启了docker。。。发现之前的停止的chaincode则无法重启了，其他fabric组件都起来了，只有chaincode容器失败，日志。

> gome-sellers-network@0.0.3-deploy.18 start /usr/local/src
> start-network "--peer.address" "peer0.org2.example.com:7052"

• 又进行了删除操作，把chaincode容器删掉,尝试重新部署chaincode,之前已经有card和管理员并进行初始化了，所以直接用composer的相关命令启动不了网络
  发现还是失败，重新install chaincode报已经初始化。下边无法进行了，只有启动了chaincode才能操作。

• 在尝试不重新操作已有card和容器，发现都不行，只能重新启动fabric网络，重新生成card导入才行。

问题

• docker重启，chaincode容器就无法再次回到之前状态（其他peer和order,ca都没问题）
• 遇到这情况需要重新部署chaincode才行，使用composer的话还有点麻烦。
