RE: Informix: Informix cooked files filesystem layout

As Art says, you will need a recent IDS version for DIRECT_IO with 4K block devices (Advanced Format storage): https://www.ibm.com/docs/en/informix-servers/14.10.0?topic=parameters-direct-io-configuration-parameter-unix <https://www.ibm.com/docs/en/informix-servers/14.10.0?topic=parameters-direct-io-configuration-parameter-unix>; https://www.ibm.com/docs/en/informix-servers/14.10.0?topic=io-kernel-asynchronous <https://www.ibm.com/docs/en/informix-servers/14.10.0?topic=io-kernel-asynchronous>; https://en.wikipedia.org/wiki/Advanced_Format <https://en.wikipedia.org/wiki/Advanced_Format>; That's from 14.10.xC13 or 15.0.1.x. Use "onstat -d" to check it's working. You are subscribed to "Informix" as paul.cdi@oninit.com.
