【问题描述】：

我有 2 个关于我们正在运行的 Seaweedfs 集群的问题。领导者使用以下命令启动：

/usr/local/bin/weed server -ip=192.168.13.154 -ip.bind=192.168.13.154 -dir=/opt/seaweedfs/volume-1,/opt/seaweedfs/volume-2,/opt/seaweedfs/volume-3 -master.dir=/opt/seaweedfs/master -master.peers=192.168.13.154:9333,192.168.13.155:9333,192.168.13.156:9333 -volume.max=30,30,30 -filer=true -s3=true -metrics.address=192.168.13.84:9091

问题 1

我使用weed scaffold -config=master 创建了一个master.toml 文件：

[master.maintenance]
# periodically run these scripts are the same as running them from 'weed shell'
scripts = """
  ec.encode -fullPercent=95 -quietFor=1h
  ec.rebuild -force
  ec.balance -force
  volume.balance -force
"""
sleep_minutes = 17          # sleep minutes between each script execution

但是维护脚本似乎失败了，因为

shell failed to keep connected to localhost:9333: rpc error: code = Unavailable desc = all SubConns are in TransientFailure, latest connection error: connection error: desc = "transport: Error while dialing dial tcp [::1]:19333: connect: connection refused"

这是有道理的，因为 master 绑定到 ip 192.168.13.154 并且维护脚本尝试连接到 localhost。如何在master.toml 文件中指定主 IP？

问题 2

卷的数量似乎比使用的磁盘空间量增长得更快。例如，在 .154 服务器上只有 11 个空闲卷。但是看看磁盘空间应该还有更多。

状态：

                "Url": "192.168.13.156:8080",
                "Volumes": 85
              }
            ],
            "Free": 16,
            "Id": "DefaultRack",
            "Max": 270
          }
        ]
      }

    "Max": 270,
    "layouts": [
      ...
    ]
  },
  "Version": "30GB 1.44"
}

磁盘 (192.168.13.154)：

/dev/sdb1      1007G  560G  397G  59% /opt/seaweedfs/volume-1
/dev/sdc1      1007G  542G  414G  57% /opt/seaweedfs/volume-2
/dev/sdd1      1007G  398G  559G  42% /opt/seaweedfs/volume-3

这与维护脚本没有正常运行有关，还是我没有正确理解其他问题？
