IDK, if related, since update to 6.11.X Windows VM freeze in about one or two hours. There is no syslog or VM log saying anything. Just freeze. Initially I was toying with virtiosfs, so. I create a new VM configuration from the scratch and the same happens. The below log dump, has with the Windows VM (Windows 11Test) in freeze state. It happens after midnight and before 8:00 AM today. Will rollback to 6.10 and report and/or remove virtiosfs and post back. maxraid-diagnostics-20221014-0849.zip

I partially fix the issue, following Matias Hueber's "Performance optimizations for gaming on virtual machines (mathiashueber.com)" on his site, mentioned the topology of a Ryzen Processor . If you see his configuration it uses the second CCX for the guest The strange thing, is the ordering is the same in the web UI. Which means cpuset = CPU number in UI. With the above all the HTs will be light up. But notice the CPU pairing is CPU 0 and CPU 8, CPU 1 and CPU 9. When in the above graphics the pairing is [CPU 0, CPU 1] [CPU 2, CPU 3] So my question is, which one of this are wrong? It seems the UI is showing the wrong pairing. I used the UI to create the cpuset, and seems that created the bottleneck. IDK: if this also is replicated on CPU Pinning but since the UI is the same I guess so.

This happening for a long time, since Windows 10, updated virtIO several times. Current running version 100.90.104.21700 (2/23/2022). The strange thing is, it's not related to the SSD cache. But entirely when mover is running VM virtio network goes down to 4 MB/S. IN/OUT the unraid. Per example, if, I mount an external share from another computer in Unraid GUI, and start copying to unraid when mover is running I got 110 MB/S probably maxing the network. So there is no bottleneck on the SSD cache (2XSATA SSD in RAID-0). Tweaked iothreadpin on the VM, with no improvements. I'm kinda baffled, where the bottleneck is, Running Ryzen 1700. CPU usage when mover is running is negligible. Of course I tested it without any load. And the issue remains. Any clues, where the bottleneck exists?

Yup, emulated. Getting two new disks next week. My issue. Is knowing what happens with those 250 sectors belonging to the third disk.

Yes Sir. Unsynced disks are: WDC_WD60EFRX-68MYMN1_WD-WX41D948YKAU-20211031-1315 WDC_WD60EFRX-68MYMN1_WD-WX51DA476XHT-20211031-1315 maxraid-diagnostics-20211031-1315.zip

Some background: I live in a country where HDD are at least two times more expensive than USA, and with the Chia craze, prices are not lowering yet, at least in here. That said. I Have a dual parity unraid, about 3 months ago, one disk start to grow bad sectors. 250 at the time of writing this. Yesterday, something unexpected happens, two disk, gone bad, and desynced. Smart is OK on both. The strange thing, is, reconstructing them, ends both after 10 minutes with 1024 errors, at the same time. Reading them directly seems to be fine. So, I'm suspecting there is power supply issue, since they're from different backplanes. That said again... Now, I have two desynced disks, that might or might not be reused, and one disk with 250 sectors bad. I Know a little about how reconstruction works, using XOR or Red Solomon. And the 3 disks are data disks. My question is the following: At the sector position where those 250 errors sectors exists, in the first disk. Can those be recuperated somehow? at the same time in the same position, those 250 sectors in the desynced drives, these data become in danger? If the answer on the above questions, is you're fine. Then I have no issues. Is the answer, is, you might loose that data. I'm looking for the following: 1) Is there a tool, that can point out what files are in danger, from the error sectors, and also extend it to other disks, same set of sectors, but different disk ? 2) Can you mount unraid in read only mode. And mark those almost broken disks temporary synced, and mount them as a part of the unraid? In that way, they serve their limited purpose, those 250 sectors can be recuperated, files can be copied to other medium, and the disks can be replaced with no risk of loose data. Also this method, could serve to recuperate files, when disks have errors, not dead, but they're in different places.

Thanks Bob, Yes, i looked into it. But seems those Ryzen still have problems with virtualization, ECC Memory & unraid stability. Since, i can wait a few months, before pulling the trigger, i should wait and see what happens with the Ryzen and the Threadripper, or swap to a more proved platform (used xeon+mobo) Regards

Thanks a lot BJP999, Will look at post, and take note of the LSI cards, one less PCI slot is a win-win Regards

Thanks TDallen, will do Do you recommend any other hw configuration? I did select ryzen because the price/benefit ratio, but i could chose intel if there is too much trouble with the ryzen part. Regards

Currently i'm using addonics cards HPM cards on several RAID 5 boxes, i want to migrate to a more stable solution, since those addonics HPM cards are given me a lot of headaches. I'm looking to buy a NORCO 4224 setup, with unraid. Usage Cases: NAS/Media Center streamer (Plex)/Download server, remote controlled. So i want two VMs. One with unraid other with Windows 10. Looking at Ryzen 1700 (High core count, high transcoding capabilities). 2x8 or 2x16 gb ECC DDR3/4 3 x 256 SSD (One for Windows 10 boot, the other two for unraid cache). 3 x LSI 9240-8i Can you give me some hardware recommendations (mobo, other CPUS, better card, etc). Also, its possible to mount the unraid volumes into the guest machine (Windows 10), without using the limited Gb ethernet network? Thanks In Advance.
