Yros

Hello, I've been wanting (for a while now) to build a full AMD system (something along the lines of a Ryzen 7900x3D with a 7900XTX) however i have concerns about power at idle and stability preventing me from actually making the move over to unraid. Regarding power at idle, it's nothing new that Intel has a clear advantage here (though I did read that downclocking and reducing the soc power voltage did help reduce amd consumption at idle). I'm also wondering whether it is possible to fully power-off the GPU when the VM is off to further reduce power consumption? (I'd be using the amd igpu for unraid and the gpu only for VM). Meanwhile, when it comes to stability, I still have concerns regarding AMD c-states and gpu's old reboot bug that have always shown issue with Linux-based distributions (unraid included). Ideally I'd like to be able to maintain power-at-idle below 50w while spinning down drives. If that's really not possible, I guess I'll have no other choice than to go for an Intel 13900k + nvidia gpu build (though I really hate the idea of paying an overpriced nvidia gpu T.T). Please feel free to share your experience especially if you have an AMD build on a recent unraid build. This represent a substantial financial investment for me since I'm considering spending about 5k€ on this build between the components and hard drives so obviously I'd like to make sure I'm not going to ruin myself here :< Thanks in advance. Any help is appreciated.

For monitoring purpose, I found those links while scrubbing the net trying to better understand ZFS: https://calomel.org/zfs_health_check_script.html https://jrs-s.net/2019/06/04/continuously-updated-iostat/ Bonus tips & tweaks : https://jrs-s.net/2018/08/17/zfs-tuning-cheat-sheet/ Someone also made a script in this thread to get mails/notifications, and Steini also offers the ZnapZed plugin for further monitoring

Yeah, a GUI with monitoring + a dedicated page with tutorial and basic commands and tweaks would do just fine I think. Though I'm not sure if allowing direct manipulation of the zpool through the GUI is a good idea, I think leaving that part in command lines is better as ZFS is quite flexible, meaning it needs precise options on a per-case basis to obtain the best benefits. (Plus it's a lot easier to make without direct modification )

There's no absolute benefit for a GUI other than being able to monitor (in real time?) the ZFS pool and maybe even some additionnal perks. Either way it's, in my humble opinion, better to have a separate space for the Zpool(s) rather than be aggregated with the Unassigned Devices plugin and risk some mishap down the line due to a erronous mounting on unraid or something. As for the script, I'll have a look though I don't promise anything (my level is basically 1st year of IT college in programming... I was more of a design' guy at the time), and I'm still trying to figure out why my GPU won't pass-through @.@

I also need the 6.9 unRaid version with 5.4x linux kernel since I'm running a x570 MB with Ryzen 3700x and AMD RX 5700 XT and the passthrough is nigh impossible for some reasons... (made a support topic about it which I should update btw). The RX 5700 XT has the amd reset bug very annoying but apparently there's a partial fix already out and that's available on the custom kernel for unraid 6.8.0-rc5, which I'm running at the moment (but I guess I'm just unlucky or I probably failed some config somewhere because it doesn't work...). ZFS can use partitions. My hope is that, once I set up the Zpool, the remainder of the 2x2Tb drives will be available for the unraid array. If not... Meh, I suppose I'll have to make another zpool just for them in raid1... ? I still have some time to iron-out the kinks since I'm still at the pre-clearing state of the drives right now so I'll start trying things out tomorrow with ZFS to get the most out of my current config'. Problem is: if I use all of my disks in the zPool, how will I start the Array T.T Maybe I'll be forced to use another user's trick and just dump a usb drive to start it... ? °I'll see°

Hi, Excellent plugin which kept me reading non-stop informations on the ZFS subject for the past two days. A huge thanks to @steini84 for this port. If I find the motivation I may even lend my meager abilities to try and see if I can't come up with some GUI plugin '-' (would have to refurbish my coding skills a bit but meh, sounds like a good project). Speaking of ZFS plugin, it doesn't seem to be updated to the latest kernel (unraid 6.8.1-rc1). I'm currently trying to get my GPU to pass-through properly through unRaid but aside from that I have quite a decent (meaning completely insane) setup in mind (involving building a RAIDZ2 zpool of 8 disks while missing two which are part of my current NAS and will be replaced after transfering the datas first + a second zpool of 2x 1Tb PCIe4 nvme drives, because, why not...). I'll let you know how it goes @.@ Oh, yes, the fun part : 2 of my 8 disks are actually 6Tb (the 6 others are all 4Tb) meaning a 2x 2Tb loss of data. I plan on partitionning those extra 2x2Tb of data to use them as the default unRaid array (for some backup and stuff). Meaning part of the 6Tb drives will be in BTRFS with the unraid array in Raid1 (one parity, one drive), while the rest will be part of the main Zpool in RAIDZ2 Does that make sense ? Since the unraid array will only be used as backup I highly doubt it will have any performance impact. What's your take on that ?

Thank you for the video. Very useful guide. I just have one tiny question : is it possible to modify the unRaid config to add the option of booting from Windows 10 Baremetal directly from the menu at the start instead of having to change in the BIOS between USB / SSD boot priority ? I've seen in another video you modified it to add a custom unraid version with isolated cores. I'd like to know if it's possible to do something similar here ?

After searching for that very answer, I found out the 'go' file in the unRAID /boot/config directory of the flash drive. I also added that line to it, saved the change, then rebooted, but apparently it did not work. My current understanding is that the chip is too recent (NCT6798D in my case which is just the next one quoted above) and not compatible with the current version of the sensors-detect and sensors present on the latest unRAID. Useful links I found during my searches: https://wiki.unraid.net/Setting_up_CPU_and_board_temperature_sensing https://hwmon.wiki.kernel.org/start (replacing the old lm-sensors.org site) https://github.com/torvalds/linux/commit/0599682b826ff7bbf9d5804fa37bcef36b0c9404 the related issue to this specific chip. https://forum.level1techs.com/t/temperature-system-monitoring-for-ryzen-3000-and-x570-motherboards-in-linux/145548 Someone with the exact same config as I who apparently managed to patch it up… I'll try to adapt it to unRAID with my little knowledge and see how it goes '-'
