Centos7安裝greenplum遇到的問題

問題1：gpcheck的時候xfs檔案系統報錯

網路解決方法：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

重啟不生效！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！

 

解決辦法：修改gpcheck的程式碼：註釋掉一行，繞過XFS mounts檢查。

 

 

問題2：gp初始化segment節點啟動失敗，檢視日誌，問題如下：

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

主節點操作不了從節點的檔案，因為沒有安裝ed編輯器ed-1.1-3.3.el6.x86_64。安裝完之後，初始化成功。
