Prompt:How 错误 我是否在 GPDB 中创建新的基于用户的文件空间
Error at Prompt:How Do I create New user based Filespace in GPDB
我们有小型 gpdb 集群。当我尝试创建基于新用户的文件 space 时。
那是
调用 gpfilespace 实用程序
$gpfilespace -o gpfilespace_config
在创建文件prompt:At时出现以下错误space。
[gpadmin@mdw dfs]$ gpfilespace -o gpfilespace_config

A tablespace requires a file system location to store its database
files. A filespace is a collection of file system locations for all components
in a Greenplum system (primary segment, mirror segment and master instances).
Once a filespace is created, it can be used by one or more tablespaces.

Please specify 1 locations for the primary segments, one per line:

我尝试了不同的方法，但用户文件 space 没有创建。
如有任何帮助，我们将不胜感激？
这个例子是我很久以前发给一个使用单节点虚拟机的客户的例子。
gpadmin$ mkdir /user
gpadmin$ cd data
gpadmin$ gpfilespace -o .

在这个单节点示例中，master 和 segments 在 /user 中。 gpseg-1 是主机，gpseg[0-1] 是段。你可以在这里看到：
gpadmin$ cd /user
gpadmin$ ls -la
