TarrifMan Posted August 2, 2019 Share Posted August 2, 2019 (edited) GPU: (AMD Radeon RX580) Since Ryzen 3700x has no integrated graphics, I had a GPU plugged in the first time I booted unraid. It started but just kept saying "amd-vi: completion-wait loop timed out." Eventually, I just shut it off, removed the GPU and it booted up fine. IOMMU is enabled in the BIOS and SVI is also enabled. I rebooted again, this time, I checked the BIOS to make sure the m.2 ssd is detected; it is but it's not showing in unraid. UPDATE: System boots and detected the GPU only if IOMMU is disabled.

trurl Posted August 2, 2019 Share Posted August 2, 2019 SSDs in the array are not recommended. They cannot be trimmed, some implementations might invalidate parity, and in any case they can't be written faster than parity anyway so I don't know why you would want to do this. SSDs in the cache pool or as Unassigned Devices is what everyone else does. 1 Quote Link to comment

JonathanM Posted August 3, 2019 Share Posted August 3, 2019 I can't find solid confirmation with a quick google, but some WD blue SSD's use marvell controllers, which are known to cause issues with linux. If you continue to have issues whenever you assign that drive, post your diagnostics so we can see which controller it uses. Quote Link to comment
TarrifMan Posted August 4, 2019 Author Share Posted August 4, 2019 (edited) Post updated. unraid only boots with GPU (RX580) if IOMMU is disabled in BIOS. Pic shows what happens when IOMMU= Auto or Enabled Edited August 4, 2019 by TarrifMan Quote Link to comment
JonathanM Posted August 12, 2019 Share Posted August 12, 2019 Same error with the NVME WD Blue removed from the system? Quote Link to comment
TarrifMan Posted August 16, 2019 Author Share Posted August 16, 2019 This happened before I ever got the NVME WD Blue. Quote Link to comment
Oakley707 Posted August 31, 2019 Share Posted August 31, 2019 For my ignorance, I'm contemplating upgrading to a Ryzen 5 3600 setup. Do I NEED a graphics card to run unRAID? I'm coming from an old crusty i3-6100 with integrated graphics. I do not use any VMs yet, so I'm not worried about having to pass it thru. I just want to make sure that the mobo will POST without a graphics card and that unRAID will work. Thank you in advance. Quote Link to comment

Whether or not the motherboard will boot however without a GPU is something dependent upon it itself. At the very least, you WILL require a GPU to at least setup the boot order in BIOS. 1 Quote Link to comment
