Probably a last note on this topic for now:
See the earlier mentioned MariaDB bug report too. In order to get this working, you should use a new secomp profile or run unconfined with docker run --security-opt=seccomp:unconfined.
That is no great advice for Docker users. You have the choice of degraded performance or lower security.

Update:
Getting a little bit closer. I opened a bug report with MariaDB.
And an older report was linked
It shows that io_uring and liburing were added on 10.6 (So my previous 10.5 did not have the issue.)
Disabling native aio could definitely lower performance.
If you have 10.6+, please check your logs !

Onderwerp: [Koha-devel] io_uring_queue_init failed with MariaDB 10.11.6 / Koha 23.11
Hi all,
I have switched from 22.11 to 23.11 while upgrading the MariaDB server from 10.5.23 to 10.11.6 (in a Docker container based on the official mariadb image from Docker hub.
I am now seeing this warning in docker logs:
2025-03-06 11:14:44 0 [Warning] mysqld: io_uring_queue_init() failed with errno 1
2025-03-06 11:14:44 0 [Warning] InnoDB: liburing disabled: falling back to innodb_use_native_aio=OFF
Have been searching and tested with more memory and raising memlock with --ulimit in the docker run statement, but to no avail yet.
You can check if MariaDB disabled this setting in your setup with mysql:
show variables like 'innodb_use_native_aio';
If it is still ON, you are probably good.
Anyone else seeing this issue or have any further clues?
Thanks,
Marcel
