It looks like you don’t have the operation permissions for that disk. Are you using the tidb user to start it? Check if this user’s folder permissions are set correctly.

I started it using the tidb user, and this user has the necessary folder permissions. I tried changing the permissions to 777, but it still reports the same error.

Check permission issues.

Try switching to the TiDB user and execute that command to see if it really works.

Permission error. You should grant 777 permissions to that directory.

Or after creating the directory, use chown -R tidb:tidb /data.
