How to install OceanBase 4.0 in autodeploy mode？

I simply set up a stand-alone server for testing purpose, the following is my configuration:

• Server configuration: 16 core, 64G memory
• Use the configuration file in the all in one in开发者_StackOverflowstallation package - single-example.yml for cluster initialization
• Deploy the cluster with autodeploy

my question: I'm currently running into a configuration problem, it looks like the auto-configuration parameters don't meet the requirements, and the following error log will be reported:

[admin@dbs06 conf]$ obd cluster start obcluster
Get local repositories ok
Search plugins ok
Open ssh connection ok
Load cluster param plugin ok
Check before start observer x
[ERROR] (172.16.10.XXX): when production_mode is True, memory_limit can not be less then 16.0G
[WARN] (172.16.10.XXX) clog and data use the same disk (/app)
[ERROR] (172.16.10.XXX) /app not enough disk space. (Avail: 6.5T, Need: 9.0T)

We can get two pieces of information from the above error log:

There is a problem with the memory configuration, which conflicts with the production mode; Disk space configuration error, where does "9T" come from?

I hope someone can help me to check if there is some misconfiguration of autodeploy, thanks.
