Errors during at 4-byte-support activation

ℹ️ Support
1

Hello,

at the admin panel on nv 15.0.7 was a message about missing 4-byte support.
I followed this manual, but now I have several error messages during maintenance:repair.
https://docs.nextcloud.com/server/15/admin_manual/configuration_database/mysql_4byte_support.html

Can someone tell me how to fix this? :roll_eyes:

This is the terminal log (full terminal input: https://pastebin.com/USFkUNnB):

In AbstractMySQLDriver.php line 115:
  An exception occurred while executing 'ALTER TABLE `oc_addressbooks` CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_bin;':

maintenance:repair [--include-expensive]

I found this bug report: https://github.com/nextcloud/news/issues/226

… and added to the mariadb.cnf
innodb_large_prefix=on
innodb_file_format=barracuda
innodb_file_per_table=true
innodb_large_prefix=1

It is running through, but with some errors.
PasteBin is updated, can someone take a look?
