建库出现问题:SQL0294N The container is already in use. SQLSTATE=42730

我在建库时为了把数据库目录和数据目录放在不同的地方，特意建了一个目录，/dbdata用于存放数据，然后使用以下命令建库，发现建不了。


CREATE DATABASE TESTDB AUTOMATIC STORAGE NO ON '/home/db2inst1' USING CODESET UTF-8 TERRITORY CN  USER TABLESPACE MANAGED BY DATABASE USING ( FILE '/dbdata/usertbs01.dat' 25600) AUTORESIZE NO  CATALOG TABLESPACE MANAGED BY SYSTEM USING ( '/dbdata' ) NO FILE SYSTEM CACHING  TEMPORARY TABLESPACE MANAGED BY SYSTEM USING ( '/dbdata' ) NO FILE SYSTEM CACHING ;

报错信息:
SQL0294N  The container is already in use.  SQLSTATE=42730


请大师们帮忙看一下，谢谢。收起
