Whenever I attempt to write over 4GB of data or when writing to an address that has already been written to, I receive the following error: "[FEMU] Err: Error IO processed!"
You cannot simply do overwrites to the same PPA. Under OC mode, it's users' responsibility to manage erases and writes. Also make sure you're not writing to invalid PPAs.
Can I get the open channel SSD performance using the same method that direct test raw device use fio as with a normal nvme drive?
Yes, create a block device on top of the /dev/nvme0n1 interface, then regular I/O benchmarks and application could run.
