Answer
Disable AIO
This fixed it for me when I got the AIO error as you did when I was starting a container from a guest Debian OS from Virtualbox and creating the database files on a shared folder on Windows 10.
The issue seems to be that AIO is not supported on shared folders, or at least on some versions of Windows. It seems to have occurred for me after I moved from Windows 10 Pro to Home after my main machine crashed.
For details:
Here are some options:
Option 1 - start the container like this :
docker run -it mysql --innodb_use_native_aio=0
Option 2 - add the command to your docker-compose file:
command: --innodb_use_native_aio=0
In context, this is the relevant portion of my working docker-compose.yml:
services:
db:
image: ${MYSQL_IMAGE}
command: "--innodb_use_native_aio=0"
volumes:
- ${DB_DATA_PATH}:/var/lib/mysql
ports:
- ${MYSQL_PORT}:3306
Option 3 -- add an option to your my.cnf file in your build
innodb_use_native_aio=0
Option 4 - Don't persist your DB on the local file system.(Can destroy your db, Not Recommended)
Simply remove the volume in your docker configuration that contains your mysql db. Of course, your DB will be deleted if you do a docker-compose down or otherwise destroy your container, so there's that.
