Centos7安装greenplum遇到的问题

问题1：gpcheck的时候xfs文件系统报错

网络解决方法：修改/etc/fstab的配置如下：

/dev/mapper/cl-root     /                       xfs     nodev,noatime,nobarrier,inode64,allocsize=16m      0 0

UUID=2d2cd8de-8d11-4cf0-8780-070a806a0fbb /boot                   xfs     nodev,noatime,nobarrier,inode64,allocsize=16m      0 0

/dev/mapper/cl-home     /home                   xfs     nodev,noatime,nobarrier,inode64,allocsize=16m      0 0

/dev/mapper/cl-swap     swap                    swap    nodev,noatime,inode64,nobarrier,allocsize=16m      0 0

重启不生效！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！

解决办法：修改gpcheck的代码：注释掉一行，绕过XFS mounts检查。

问题2：gp初始化segment节点启动失败，查看日志，问题如下：

20180725:14:15:18:013574 gpcreateseg.sh:bigdata-3-22:iflytek-[WARN]:-Failed to insert port=40000 in /home/iflytek/greenplum/data/primary/gpseg1/postgresql.conf on bigdata-3-24

20180725:14:15:18:013574 gpcreateseg.sh:bigdata-3-22:iflytek-[INFO]:-End Function ED_PG_CONF

20180725:14:15:19:013574 gpcreateseg.sh:bigdata-3-22:iflytek-[FATAL][1]:-Failed Update port number to 40000

主节点操作不了从节点的文件，因为没有安装ed编辑器ed-1.1-3.3.el6.x86_64。安装完之后，初始化成功。
