出现这个问题有以下几种可能：

1.gpmaster/目录下磁盘已满，没有启动所用的空间；

解决：删除不用的数据。留有足够的空间

2.数据库升过级后，忘了改环境变量或是环境变量设置的有问题

解决：环境变量修改正确即可，实例如下：

[gpadmin@mdw ~]$ more .bash_profile

# .bash_profile

# Get the aliases and functions

if [ -f ~/.bashrc ]; then

. ~/.bashrc

fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin

export PATH

[gpadmin@mdw ~]$ more .bashrc

# .bashrc

# Source global definitions

if [ -f /etc/bashrc ]; then

. /etc/bashrc

fi

# User specific aliases and functions

source /usr/local/greenplum-db/greenplum_path.sh

export MASTER_DATA_DIRECTORY=/data/master/gpseg-1

source /usr/local/greenplum-cc-web-1.2.0.1-build-2/gpcc_path.sh
