Thanks to @ich777 for the breakthrough that got my Fusion-io ioDrive2 up and running in Unraid 7.2.5. I was able to compile the RemixVSL (iomemory-vsl) driver against kernel 6.12.85-Unraid using the ghcr.io/ich777/unraid_kernel:gcc_14.2.0 Docker container. The card is now working natively in Unraid as /dev/fioa . My drive turned out to be essentially unused, with only about 4 MB of lifetime writes. I documented the full step-by-step process, including: Ubuntu Server 22.04 diagnostics and firmware update Driver selection (RemixVSL VSL3) Kernel module compilation Persistent module loading Filesystem creation and mounting Benchmark testing Full technical guide (PDF)
