O_DIRECT support for host-mounted volume #1619

Cross-posted from the MS SQL Server tracker: https://github.com/Microsoft/mssql-docker/issues/12

SQL Server requires underlying filesystems to support the O_DIRECT file option so that we can use asynchronous I/O. It appears that Docker's OS X volume mapper doesn't support this. We also require O_DIRECT because SQL Server expects unbuffered I/O to the disk.

Question: since paragon software has the ability to read/write ntfs volumes, can docker use the tool to support async i/o? Is there a way to test this? thanks in advance for any guidance. https://paragon-software.com/. I am also reaching out to Paragon Software about this topic.
