参考手册上说是可以的。

操作系统版本：

[****]$ lsb_release -a
LSB Version: :core-4.0-amd64:core-4.0-ia32:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-ia32:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-ia32:printing-4.0-noarch

在虚拟机上做测试是成功的，文件夹权限是777如下：

mysql> CREATE TABLE ts (id INT, purchased DATE) engine=myisam
    -> PARTITION BY RANGE(YEAR(purchased))
    -> SUBPARTITION BY HASH(TO_DAYS(purchased))
    -> (
    -> PARTITION p0 VALUES LESS THAN (1990)
    -> (
    -> SUBPARTITION s0a
    -> DATA DIRECTORY = '/home/zxy/d1'
    -> INDEX DIRECTORY = '/home/zxy/d2',
    -> SUBPARTITION s0b
    -> DATA DIRECTORY = '/home/zxy/d1'
    -> INDEX DIRECTORY = '/home/zxy/d2'
    -> )
    -> )
    -> ;
Query OK, 0 rows affected (0.48 sec)

虚拟机操作系统版本：

[root@localhost ~]# lsb_release -a
LSB Version: :core-4.0-ia32:core-4.0-noarch:graphics-4.0-ia32:graphics-4.0-noarch:printing-4.0-ia32:printing-4.0-noarch
Distributor ID: CentOS
Description: CentOS release 5.7 (Final)

对比之后发现，是操作系统的问题。64位系统下不行，32位系统下可以。64位下不行的原因还未知，有知道的指点一下。
