I'm in the process of migrating from a single Unraid box to virtualizing it using Proxmox. I've installed Proxmox, created a VM and setup the pass through for the physical drives (not for the entire PCIe). Unraid boots and looks fine, but when I try to setup the disks, pointing the scsi-disk to where the previous physical disk was, it displays the message "Wrong" and "Parity device is disabled" and "Device is disabled, contents emulated". It doesn't allow me to start the array. My Proxmox setup: Unraid disk setup: How can I fix this, preferably without passing through the entire controller? (can't see it in the list and I want to add drives not used in Unraid to it).

Thank you for your answe, @JorgeB! I've setup my PC and ran tests against the share and directly against the cache. Both were actually at 96-98 Megabyte/s, so the problem doesn't seem to be the cache, after all. I also tried local dd, with larger block size, and that seemed to increase the speed as well. Can it be that the small block size, when running locally, increases I/O? And that's hard for the shfs to handle? However, I still seem to be limited to 25-30 Megabyte/s in all torrent clients I've tried. qBittorrent, rTorrent, Deluge. From my other PC, I reach speeds at 60 Megabyte/s+ with no problem. Could it be that the torrent clients has high I/O, and that, as in the dd with a block size of 1kB, leads to poor performance?

Some more information, it seems that the shfs process is taking some CPU when doing the dd tests, if that's of any interest. Both these screenshots from when running dd to /mnt/user/.

Ran a dd with Tunable (enable Direct IO) turned to yes, with no difference at all: # dd if=/dev/zero of=/mnt/user/media/test-user bs=1K count=5000000 conv=fdatasync 5000000+0 records in 5000000+0 records out 5120000000 bytes (5.1 GB, 4.8 GiB) copied, 189.436 s, 27.0 MB/s

Some other topics with same/similar problem, but without any solution.

I have set up a share that uses an SSD as cache. However, something seems to be very wrong. My writing speed to /mnt/user/share are around 25-30 Megabyte/s, even though I'm having an SSD cache and the "Use Cache Pool" setting at "Yes". I noticed that my qBittorrent was always at a maximum of 25 Megabyte/s. I have 750 Mbit/s internet and always get 500 Mbit/s+ in speed tests and reaches speeds at 70 Megabyte/s+ on my other computer. I tried to search and found out more people who seem to have had the same problem, but I couldn't find any solution. I've tried setting Tunable (md_write_method) to reconstruct write, but that doesn't affect speed. (I guess it shouldn't either, as the data is written to cache and the parity is not involved.) My server specs: Motherboard: Supermicro X12STH-LN4F CPU: Intel Xeon E-2356G Memory: 2*32 GB ECC RAM Hard drives: 3*Seagate Exos X16 16 TB 7200 RPM (1 parity, 2 data) - Data is xfs encrypted SSD cache: 1 TB Samsung 970 EVO Plus NVMe M.2 - SSD is btrfs encrypted Unraid version: 6.10.0-rc4 I ran some dd tests and these are the results: # dd if=/dev/zero of=/mnt/user/media/test-user bs=1K count=5000000 conv=fdatasync 5000000+0 records in 5000000+0 records out 5120000000 bytes (5.1 GB, 4.8 GiB) copied, 209.546 s, 24.4 MB/s # dd if=/dev/zero of=/mnt/cache/media/test-cache bs=1K count=5000000 conv=fdatasync 5000000+0 records in 5000000+0 records out 5120000000 bytes (5.1 GB, 4.8 GiB) copied, 8.50469 s, 602 MB/s # dd if=/dev/zero of=/mnt/disk1/media/test-disk1 bs=1K count=5000000 conv=fdatasync 5000000+0 records in 5000000+0 records out 5120000000 bytes (5.1 GB, 4.8 GiB) copied, 23.7756 s, 215 MB/s I've verified that the dd test to /mnt/user is written to the share, and not disk. I've attached the diagnostics, collected after I ran the dd tests. No reboot. Below are some images of my settings.

I want ECC and iGPU, so I've decided to build my new system using a Xeon E-23xxG processor. The number of available (mATX) motherboards for the Intel C252/C256 chipset is currently very limited though. As of speaking, the distributors where I live can get me my hands on two Asus boards: Asus P12R-M Asus P12R-M/10G-2T They seem good enough to me*, with 6 SATA and 1 M.2, and some PCIe slots. The difference between them is that the 10G-2T version comes with 2 10Gbe LAN, which is the one I'm thinking about buying. But I can't find any info about support for those NICs. The chipsets are Intel X710-AT2. Anyone knows if they are supported in unRAID? Or if I instead should go for the 1Gbe version? And I guess there should be no problem using the Xeon E-23xxG processor iGPU (UHD P750) in something like Plex or Jellyfin? Since I guess it's the same iGPU as in the non-xeon 11th gen CPU's, that seems to be working. * Would've loved the Super Micro C256 board with 8 SATA and one more PCIe x3 slot, though, but availability is none.
