SST failed to match "Data Directory"

MySQL & MariaDB Percona XtraDB Cluster 5.x

Hi Everyone,

Assuming I create a table such as below on Server A on stand alone mode:

CREATE TABLE external (x int unsigned not null primary key) DATA DIRECTORY = ‘/mnt/external1/data’;

The new server that joins the cluster (Server A) does not apply the location of table into “/mnt/external1/data”

The table “x” must be save be saved in “/mnt/external1/data” but instead it is saving in default “datadir” path (“/var/lib/mysql”) .

How to overcome this?

Regards

did u try this…?
Change the default datadir path in the joining node’s my.cnf file!
datadir = path to datadir

My datadir on all servers are the same,
I only want to relocate small tables that are frequently accessed to SSD hard drive or RAMFS location for fast read/write…
