Question

我正在跟踪this instruction在我的kubernetes集群上设置glusterfs。在heketi-client/bin/heketi-cli setup-openshift-heketi-storage部分，heketi-cli告诉我：

错误：创建卷：heketidbstorage：失败：主机192.168.99.25未连接

或有时：

错误：卷创建：heketidbstorage：失败：在192.168.99.26上登台失败。错误：主机192.168.99.25未连接

heketi.json是

          ]
        }
      ]
    }
  ]
}

heketi-cli是v8.0.0，而kubernetes是v1.12.3

如何解决此问题？

更新：刚刚发现我错过了iptables部分，但是现在消息变成了

错误：创建卷：heketidbstorage：失败：主机192.168.99.25不在“对等集群”状态

我似乎尝试了kubectl exec -i glusterfs-59ftx -- gluster peer status：glusterfs吊舱之一无法与其他吊舱连接：

Number of Peers: 2

Hostname: 192.168.99.26
Uuid: 6950db9a-3d60-4625-b642-da5882396bee
State: Peer Rejected (Disconnected)

Hostname: 192.168.99.113
Uuid: 78983466-4499-48d2-8411-2c3e8c70f89f
State: Peer Rejected (Disconnected)

而另一个人说：

Number of Peers: 1

Hostname: 192.168.99.26
Uuid: 23a0114d-65b8-42d6-8067-7efa014af68d
State: Peer in Cluster (Connected)

Answer 1

我自己解决了这些问题。

首先，原因是我没有根据Infrastructure Requirements在每个节点中设置iptables。

根据this article的第二部分，删除/ var / lib / glusterd中除glusterd.info之外的所有文件，然后从Kubernete Deploy重新开始。

在Kubernetes上设置glusterfs时发生错误：卷创建：heketidbstorage：失败：主机未连接
