Description
I start a MariaDB Linux server on a case insensitive file system with --lower-case-table-names=2.
Now run these scripts:
CREATE DATABASE db_myisam; |
CREATE TABLE db_myisam.`O` (a INT) ENGINE=MyISAM; |
CREATE TABLE db_myisam.`Ó` (a INT) ENGINE=MyISAM; |
CREATE TABLE db_myisam.`#mysql50#Ó` (a INT) ENGINE=MyISAM; |
CREATE DATABASE db_aria; |
CREATE TABLE db_aria.`O` (a INT) ENGINE=Aria; |
CREATE TABLE db_aria.`Ó` (a INT) ENGINE=Aria; |
CREATE TABLE db_aria.`#mysql50#Ó` (a INT) ENGINE=Aria; |
CREATE DATABASE db_innodb; |
CREATE TABLE db_innodb.`O` (a INT) ENGINE=InnoDB; |
CREATE TABLE db_innodb.`Ó` (a INT) ENGINE=InnoDB; |
CREATE TABLE db_innodb.`#mysql50#Ó` (a INT) ENGINE=InnoDB; |
Then I execute these `ls` commands in the data directory:
ls -l db_myisam/
|
ls -l db_aria/
|
ls -l db_innodb/
|
The output is:
ls -l db_myisam/

Notice, MyISAM and Aria tables have equal letter case in *.frm and data files (MAD/MAI,MYD/MYI). For example, O.frm and O.MYD.
InnoDB tables have different letter case in *.frm vs *.ibd files, for example: O.frm vs o.ibd.
It should be possible to move a --lower-case-table-names=2 data directory to a case sensitive file system and run the server with --lower-case-table-names=0 on it.
MyISAM and Aria work correctly. InnoDB does not.
