Change of InnoDB page size at XtraDB Cluster 5.7.18

[sigim]

Hi,

as our servers (Ubuntu 16.04.1) run on SSDs with 4k blocks (ext4), I tried to change the InnoDB page size from 16K to 4K as suggested in several performance guides. As this is a new server, there is no data which can get lost. I tried it this way:

1. Install XtraDB Cluster (https://www.percona.com/doc/percona-xtradb-cluster/LATEST/install/apt.html) and run

service mysql stop

2. Created an own my.cnf with

[mysqld]
innodb-page-size=4k

3. Delete MySQL data with

rm /var/lib/mysql/* -R

4. Initialize new MySQL Instance

mysqld --defaults-file=my.cnf --initialize --user=mysql

This fails with the following error:

[ERROR] InnoDB: Invalid page size=4096

Is there another way to change the innodb-page-size for the XtraDB Cluster? I’m just curious, because this works for Standard MySQL 5.7 Server.

Thanks.
