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

The error message suggests that the drive or filesystem you are using does not support the O_DIRECT flags. This is a requirement for MinIO erasure coding.

O_DIRECT is a flag used by applications to perform direct I/O, bypassing the operating system's buffer cache. This is important for data integrity and performance in certain scenarios, such as erasure coding.

To resolve this issue, you will need to use a drive or filesystem that supports O_DIRECT. Some filesystems that support O_DIRECT include XFS, ext4 with the data=direct option, and ZFS.

If you are using a network-attached storage (NAS) device, make sure it supports O_DIRECT as well. Some NAS devices have their own configuration options for enabling direct I/O.

Once you have a suitable drive or filesystem, you can try again with MinIO erasure coding and should no longer encounter the mentioned error
