Description
HI. I try to move (rotate) old partiotions to another local directory (another hard drive). Unfortunately, "data directory" is ignored by "alter table...reorganize partition" statement without any error/warning. For example:
1. "create table" with "data directory" is OK
MariaDB [(none)]> select @@version; |

1 row in set (0.00 sec) |
MariaDB [(none)]> use test |
Database changed |
MariaDB [test]> CREATE TABLE `part_test` ( |
-> `id` int(10) unsigned NOT NULL, |
-> PRIMARY KEY (`id`) |
-> ) ENGINE=InnoDB
|
-> PARTITION BY RANGE (`id`) |
-> (
|
-> PARTITION p1 VALUES LESS THAN (100), |
-> PARTITION p2 VALUES LESS THAN (200) DATA DIRECTORY = '/var/lib/mysql_parition_moving/' |
-> );

Query OK, 0 rows affected (0.12 sec) |
MariaDB [test]> show create table part_test \G |
*************************** 1. row ***************************

Table: part_test |
Create Table: CREATE TABLE `part_test` ( |
`id` int(10) unsigned NOT NULL, |
PRIMARY KEY (`id`) |
) ENGINE=InnoDB DEFAULT CHARSET=utf8 |
PARTITION BY RANGE (`id`) |
(PARTITION `p1` VALUES LESS THAN (100) ENGINE = InnoDB, |
PARTITION `p2` VALUES LESS THAN (200) DATA DIRECTORY = '/var/lib/mysql_parition_moving' ENGINE = InnoDB) |
1 row in set (0.00 sec) |
"p2" parition file is in the right directory:
[snen]# ls -lh /var/lib/mysql_parition_moving/test/
|
total 96K
|
-rw-rw----. 1 mysql mysql 96K дек 11 15:29 part_test#P#p2.ibd
|
2. try to move "p1" to "p2" directory also
MariaDB [test]> alter table part_test REORGANIZE PARTITION p1 into (PARTITION p1 VALUES LESS THAN(100) DATA DIRECTORY '/var/lib/mysql_parition_moving/'); |
Query OK, 0 rows affected (0.31 sec) |

"p1" parition file is NOT in the right directory:

|
total 96K
|
-rw-rw----. 1 mysql mysql 96K дек 11 15:29 part_test#P#p2.ibd

PS
10.1.26-MariaDB has the same behavior
mysql 5.7.20 works fine (p1 moved)
