原因：

    glusterfs配置文件(/etc/glusterfs/glusterd.vol)出现问题

   出现问题时的配置信息为：

    volume management
       type mgmt/glusterd

        #working-directory的位置为/var/lib/glusterfsd
        option working-directory /var/lib/glusterfsd

        option transport-type socket,rdma

        option transport.socket.keepalive-time 10
        option transport.socket.keepalive-interval 2
        option transport.socket.read-fail-log off
    end-volume

处理方法：

    将working-directory的位置修改为配置文件所在位置（即为/etc/glusterfs)

    修改后的配置信息为：

volume management
    type mgmt/glusterd
    option working-directory /etc/glusterfs
    option transport-type socket,rdma
    option transport.socket.keepalive-time 10
    option transport.socket.keepalive-interval 2
    option transport.socket.read-fail-log off
#   option base-port 49152
end-volume
