Unable to create mysql files with innodb_page_size=64k

Hi,

We encountered an issue while trying to set innodb_page_size = 64k

It worked with Percona Server, it does not with PXC

Reproduction step, starting from a fresh install:

• service mysql stop

• rm -rf /var/lib/mysql

• Setting "innodb_page_size = 64k" in .cnf

• service mysql start

These steps work for Percona Server or Oracle MySQL

We always see the same logs :

2019-10-28T17:43:20.890647Z 0 [ERROR] InnoDB: Invalid page size=65536.

I even tried to recreate it with:

mysqld --user=mysql --defaults-file=my.cnf --initialize --innodb-page-size=64k

But it seems it is ignored and creates it with 16k pages

We also tried to reboot server between file deletion and service restart.

Did we miss something ?

Thanks,
