如何在Hyperledger Fabric中执行"peer node pause"命令？

Question

如果我运行这个命令peer node pause -c mychannel，会出现以下错误;

Error: as another peer node command is executing, wait for that command to complete its execution or terminate it before retrying: lock is already acquired on file /var/hyperledger/production/ledgersData/fileLock
Usage:
peer node pause [flags]
Flags:
-c, --channelID string   Channel to pause.
-h, --help               help for pause
/opt/gopath/src/github.com/hyperledger/fabric/peer # peer node pause -h
Pauses a channel on the peer. When the command is executed, the peer must be offline. When the peer starts after a pause, it will not receive blocks for the paused channel.

I理解执行此命令需要对等体处于离线状态。但是我怎样才能让同伴脱机呢?没有Peer node stop这样的命令。我看到的唯一方法是使用docker命令来停止容器，但这没有任何意义，因为如果我停止容器，我将无法进入容器。

谁来帮我执行peer node pause命令!

检出启动容器的命令。

使用命令启动对等容器时:peer node start命令。根据fabric文档，peer node start命令—启动一个与网络交互的节点。因此，当您启动容器时，节点正在启动，我还没有尝试过，但是您可以使用peer node pause -c mychannel替换该命令，因为节点尚未启动，这意味着对等体处于脱机状态。你可以试试这个
