关于AIX lv 4k offset问题初步了解(四)

SQL> create tablespace gtlions datafile '/dev/rlvtest' size 10m;

Tablespace created.

SQL> exit

Disconnected from Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit Production

With the Partitioning, OLAP, Data Mining and Real Application Testing options

db1:/oracle$ /oracle/app/oracle/product/10.2/db1/bin/dbfsize /dev/lvtest

Database file: /dev/lvtest

Database file type: raw device

Database file size: 1280 8192 byte blocks

而且使用有offset的lv创建表空间的时候在后台日志也会做相应的记录并提出建议：

create tablespace gtlions datafile '/dev/rlvtest' size 10m
