Centos7安装greenplum遇到的问题

问题1:gpcheck的时候xfs文件系统报错

20180725:09:02:11:002498 gpcheck:bigdata-3-22:hahahahah-[ERROR]:-GPCHECK_ERROR host(bigdata-3-24): potential NTPD issue.  gpcheck end time (Wed Jul 25 09:02:10 2018) time on machine (Wed Jul 25 09:02:13 2018)

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。
