Thanks! I'll check that. I was hoping that wasn't it but I can settle for a SATA SSD for the VM drive instead. Edit: Spot on, when a 2nd M.2 is installed SATA ports 5 & 6 are disabled.

Hello, weird issue I encountered while adding some hardware to my new Plex server (on truenas server). I preface this by saying I had no issues on the TrueNAS side and had everything working smoothly before I added the second m.2 drive. My hardware is as follows CPU: Ryzen 5600G RAM: 2x8GB Corsair vengeance LPX DDR4 3600MHz Motherboard: Asus Prime B550 plus Storage: 1x Samsung 850 pro 256GB SATA SSD (boot disk) 2x Samsung 980 500GB NVMe M.2 SSD. (installing the second one is when the issue started. 3x Seagate Ironwolf 4TB SATA HDD's. My original setup used the 3 4TB drives in raidz for 8TB storage with one 500GB M.2 as a cache drive. 256GB SSD is the boot drive and not usable for anything else inside of TrueNAS. I installed the second M.2 with for use for a window VM. When I rebooted, TrueNAS said my pool was unavailable and upon further investigation only 1 of the 4TB HDD's and 2 500GB M.2 SSD's were recognized. I thought at first it was a TrueNAS issue but started reversing my steps and noticed if I removed the new M.2 all the HDD's are recognized. Is there an issue with having 2 M.2 NVMe drives and that many SATA drives? Edit: Removing the new M.2 makes everything go back to normal and TrueNAS has no issues with the my pool and Plex server runs normally.
