milvus Drive export does not support O_DIRECT flags MinIO erasure coding requires filesystems with O_DIRECT support

The error message you received indicates that the Milvus Drive storage system does not support the O_DIRECT flags for the '/export' directory.

O_DIRECT is a flag used in file input/output (I/O) operations to bypass the operating system's cache and directly access the underlying storage device. It is required by MinIO erasure coding, which is a data protection technique used by the MinIO object storage system.

To resolve this issue, you need to ensure that the filesystem used by Milvus Drive supports O_DIRECT. If the current filesystem does not support it, you may need to consider using a different filesystem that does support O_DIRECT or configure Milvus Drive to use a different directory or storage system that supports O_DIRECT.

Also, make sure that your operating system supports O_DIRECT as well. Some older or less common operating systems may not have support for this feature.

Consult the documentation or support resources for both Milvus Drive and MinIO for more specific instructions on how to configure or troubleshoot these systems in your environment
