The designated data directory MySQL is unusable

Question

I use bitnami/mysql to use mysql in k8s. I used this command:

helm install my-sql bitnami/mysql --set global.storageClass=rook-cephfs --set image.debug=true --set auth.rootPassword="SAra131064" --set auth.username=ali --set auth.password=ali1234 --set volumePermissions.enabled=true

but I got error:

The designated data directory /bitnami/mysql/data/ is unusable

After that I use diagnosticMode and execute this command ( /opt/bitnami/scripts/mysql/entrypoint.sh /opt/bitnami/scripts/mysql/run.sh ) in pod and get that error again. before this command there isn't any file in /bitnami/mysql and

total 0
drwxrwxrwx 2 1001 1001  0 Dec 15 14:15 .
drwxr-xr-x 3 root root 19 May 11  2022 ..

After execute that command:

total 0
drwxrwxrwx 3 1001 1001  1 Dec 15 14:18 .
drwxr-xr-x 3 root root 19 May 11  2022 ..
drwxr-xr-x 2 1001 root  1 Dec 15 14:18 data

and there is auto.cnf in data directory.

What is the problem? What should I do? Please help me

Answer 1

Disabling the innodb_use_native_aio as your storage doesn't support it.

Add this to your my_custom.cnf file like:

[mysqld]
innodb_use_native_aio=0
