TECHNICAL BULLETIN
When using a DDP volume as a Framestore (/mnt/StorageMedia) for Autodesk Flame, the DL_DISABLE_DIRECT_IO flag is required. This flag is functional in Flame 2018.1 but has been broken in Flame 2018.2. As such, DDP/Flame users should not update to Flame 2018.2. However, Flame users can still use a DDP volume to Read and Write file sequences as soft import in 2018 update 2.
This error has been reported to and confirmed by Autodesk. The DirectIO flag will be fixed in an upcoming flame release.
Don't hesitate to contact us with any questions you may have.
