Matrix Posted November 24, 2018 Share Posted November 24, 2018 Background: I am quite capable with computers, but new to Linux. I have a decent storage collection ~25TB which is fully backed up. I am looking to consolidate my storage into an unraid array with 2 parity drives. I have watched most of Spaceinvader's videos and feel I have a good grasp of what is can do and feel I am almost ready to take the plunge. What I want: I want unraid to run an array of all my dives, and 4 cache drive SSDs to run dockers, VMs and backup of those (maybe not all cache drives, backups can be unassigned drives?) I will also be running a full time Windows 10 VM with primary GPU passthrough (GTX 770). I have already downloaded and modified the bios for the GPU. I will also be running a Plex docker and an openVPN docker. Issues so far: First I wanted to try unraid on my HTPC with 2 SSDs to mess around with. I created a bootable USB drive with the unraid tool. Modified the computer bios to boot from the USB, still booted to Windows. Removed all drives except the USB from boot devices, still booted to Windows somehow. Recreated the USB manually, ran the make_bootable.bat as administrator and retried. Same issues. I changed boot options to legacy and tried again to boot from USB. Still didn't work. I removed the Windows SSD, only boots to bios, will not even attempt to boot or go to dos. Works fine to boot from USB if it is a Windows bootable install...totally stumped here. Only thing I can speculate is that it is the P.O.S. Biostar motherboard. Second issue after I gave up with that is went to my server to test it. Did one time boot override and boots to unraid, chose non-gui to connect with my other computer, everything booted except I cannot get a valid IP. Started with something like 169... and was not showing up on my router as a device. I was unable to find a decent amount of discussion with this and not sure what could be the issue, with either of these problems. This was late last night and have been unable to test anything else as people are using Plex all day so far. Was hoping to get some advise before I have the chance to test again. I really want this to work as I need unraid at this point, but want to test it at least a bit before dropping $130 on the software (18 drives to start with). Link to comment
trurl Posted November 24, 2018 Share Posted November 24, 2018 Did you try a different USB port? Preferably USB2. 169.x.x.x means you aren't getting DHCP for some reason. Link to comment
Matrix Posted November 24, 2018 Author Share Posted November 24, 2018 I did only try one USB port, but it was a USB 2.0 port. It was connected for about 5 mins, as that was the only solution I found was that it took a min to get an IP address. Something I thought about was that my router assigns a specific IP to that computer when it is booted to Windows. Not sure if that is MAC binding to the nic, the windows install, or something else. Also not sure that would matter, as unraid should just receive the set IP and not know one way or the other. Link to comment

Matrix Posted November 25, 2018 Author Share Posted November 25, 2018 Solved the issue with it not getting an IP address. I booted it again and into GUI mode, and noticed I was unable to login, in fact my mouse and keyboard weren't even powered. I moved USB ports and during boot I noticed it said bond0 not found. I went back into bios and noticed IOMMU was disabled. I realize this is used for VMs and such, but apparently you cannot even use unRAID unless it is enabled. Worked fine after I changed it. Just a FYI for anyone in the future. Still have no idea why I can't sandbox this on my other PC, but that is more than likely a hardware issue. Link to comment

Have you tried all the available USB ports? If that doesn't help try a different brand of flash device. What is your motherboard model number? Link to comment

Unraid does not require IOMMU and VMs only need it if you need to passthrough some hardware. Not sure what caused your results. Link to comment

Does not seem like that should matter for just booting up unraid, but that did fix it. motherboard: GA-970A-DS3P Link to comment

Not sure what caused your results. Ya, that's what I thought, but it is reproducible. If I disable IOMMU no USB devices work, bond0 is not found and I don't think it even sees the hard drives, but can't be sure of that last one without getting into the GUI. It's weird because I do get the display output; this makes no sense, but it doesn't matter at this point. It works and I was planning on doing GPU passthrough to a VM anyway, so I needed IOMMU enabled. Link to comment
