一开始使用如下配置了单台数据库服务器：
user:
username: admin
password: 123456
oceanbase-ce:
servers:
- name: server1
ip: 192.168.56.120
global:
production_mode: false
memory_limit: 8G
system_memory: 1G
__mini_full_resource_pool_memory: 1073741824
datafile_size: 10G
log_disk_size: 10G
enable_syslog_wf: false
max_syslog_file_count: 4
appname: obcp1
# root_password: # root user password, can be empty
# proxyro_password: # proxyro user pasword, consistent with obproxy's observer_sys_password, can be empty
cluster_id: 1764318625
root_password: 9pNSpelCEH55ClJ1rxFl
server1:
mysql_port: 2881
rpc_port: 2882
obshell_port: 2886
home_path: /home/admin/observer
# The directory for data storage. The default value is $home_path/store.
# data_dir: /data
# The directory for clog, ilog, and slog. The default value is the same as the data_dir value.
# redo_dir: /redo
zone: zone1
建立表后，将配置修改为1-1-1架构的集群配置，然后使用"obd cluster redeploy obcp1",发现前面建立的表和数据又没有了？
