If I remember correctly - since this was a year ago - I left Memtest running for an hour or so, and only then some errors started showing up. So, run it multiple times in a row, not only once.

Thanks again, I will do that. But since I'm quite a noob, is there a guide on how to do that?

Thanks for the advice! I ran memtest and received many errors from the last test (bit fade test, 2 patterns - see the attached screenshot). The Corsair DDR5 RAM has a lifetime warranty, so I sent them back for replacement. However, backing up and recreating the pool will pose an issue as I do not have enough space to backup ~16TB of data! Any suggestions? Is there any other solution to repair the filesystem? Anyway, I'll will replace the RAM and see what happens next.

For a few days now, I've had issues while trying to write data on my Unraid server from my Windows PC. Nothing has changed but when I'm trying copy a file from my PC to the server or create a new folder I receive an error message with "error 0x8000ffff catastrophic failure". I've seen similar issues on the forums but I was not able to figure out how to solve it. So it seems my NVME (cache) throws some errors and enters read-only mode. Restarting the server - or putting the array in maintenance mode and then bringing it back to normal - usually works for a random number of hours but today it failed twice in less than 2 hours. I have added the diagnostics and a section of the system log that shows both moments of failure from today. Thanks a lot for your help! syslog.txt tower-diagnostics-20241104-2117.zip

After having some issues with my Unraid machine a couple of months ago, I upgraded from 6.12.11 to 7.0.0-beta2. It did not help, as the issue was a hardware one - which I managed to solve quite easily. The server works OK. I'm using a Handbrake docker for video encoding and this brings a different issue: if I encode a higher volume of files at once (sequentially, not in parallel, of course) at some random point - it can be after 3 files or 20 - the whole server is stuck, I have to turn it off and back on. Before digging into more details on Handbrake configuration and see what may cause that issue, I was thinking to downgrade my Unraid to a stable release - either 6.12.11 (last installed before 7 beta 2) or 6.12.13 (last stable one). I searched to see if are there any recommendations on this topic or if I may run into any issues, but I could not find any comments or posts. Before starting the downgrade I saw this message: "You are about to downgrade your server to an older version of Unraid OS Please review the changelogs from your current version, 7.0.0-beta.2, to your requested downgrade version,..." but looking at the changelogs I could not find anything that may create problems (unless I miss something). So, TLDR: are there any things that I should be concerned about if I downgrade from 7.0.0-beta2 to 6.12.11/13? Thanks a lot!

Hello, Right now I'm running my Unraid server on the following combo: - CPU: Intel i7-7700K - MB: Gigabyte Z270M-D3H - RAM: 16GB DDR4 - Storage: 1x16TB Seagate (parity) + 4x8TB Seagate (array) + 1xADATA Legend 800 1TB (cache) I just added an Intel ARC A380 GPU to use the server as an encoding machine (AV1 and HVEC) and, occasionally, plus NAS and PLEX server. However, without ReBAR, the encoding performance of the A380 is halved, much better than the UHD630 from the CPU, but much worse than what it can be. I want to do an upgrade as follows: - CPU: I would go with an i5-12400F (since I already have the GPU I do not need an IGP) but I'm also looking at an i-5 13400F or i5-13500, depending on the deals I might get on the last 2. - MB: anything mATX Intel that supports 6 SATA - the issue here is the offer is very limited for 6 SATA MB but I found a couple of good deals like ASRock B660M Steel Legend or BIOSTAR B760MX2-E Pro D4. They're both DDR4 MBs, so no need for new RAM. I trust Asrock more, so I think I'll go with that one. Now, my 2 questions related to this upgrade: 1. Is there anything specific I need to do for my Unraid server before the upgrade? Or I'll just swap the parts and that's it? 2. I have a Dell LSI 9207-8i adapter I'm not using yet, as a future-proof solution in case I want to add more storage. If I get a 4SATA MB - the offer is much more varied than the 6SATA one - and add the Dell adapter (since I have 5 HDDs), will it be able to recognize my array from the start? Or is there something I should be aware of with the new setup? Thanks a lot for any answer!

I'm following up on my above post: I have acquired the ARC380 and installed it on my server. I encoded a few files (1080p, H.265 on Intel QSV 10-bit) but to my surprise, the encoding time on the ARC 380 is the same as the one from the i7-7700K, double of the 12700K encoding time - using the same settings (I'm talking about ~125fps for i7-7700K/UHD630 and ARC 380 vs ~250fps for i7-12700K. So, I'm left with a couple of questions: - how can I check what hardware is used for encoding: ARC 380 or UHD 630? I think Handbrake is, somehow, still using the iGPU even if I disabled it from the BIOS! - since I can't activate ReBAR (not available for 7700K/Z270 chipset), might this be the most I can get from ARC 380? Thanks!

Hello, I have an Unraid server based on an i7-7700k CPU. I use it mainly as NAS but want to start encoding and arranging my video file collection. Mostly I'm talking about 4K or 1080p sources, I won't change the resolution and want to use the Intel QSV H.265 10-bit. The actual speed I can reach with the 7700k is around 25fps during 4K encoding. On a i7-12700k the speed is almost double (48-50fps). I was thinking of acquiring an Intel Arc A380 (120 EUR) to increase the encoding speed, but I couldn't find any comparisons between any of the i7s and an A380... so I'm not sure if that's a good idea. Does anyone have experience and can share some feedback about ARC QSV H265 encoding? Also, I know that Intel ARC GPUs had (have?) issues with Linux due to their drivers... were they fixed, are they running OK on Unraid? Thanks a lot! LE. I can't use ReBAR on the Unraid server as the MB has an Intel Z270 chipset that does not have the ReBAR capability.

Hello, I have read the documentation and checked a few how-to videos on YT, but I want to be sure I'm not screwing anything up. So, right now I have an array with a single drive parity, all disks are 8TB. I have bought a 16TB new drive to replace the current parity disk - thinking to the future expansions, too. I want to add the actual parity as a disk in the array - so I'll move from 4x8TB (1parity+3disks) to 1x16TB(parity) + 4x8TB (disks). They way I see it should be done is to add the 16TB as a 2nd parity, let it rebuild the array and, when it finishes, remove the 8TB parity and add it as a disk in the array. Is my approach correct and safe? Or should I take something else into consideration? Thanks a lot!

Thanks for the hint, I have changed that setting and the transfer speed it's constantly around 165-170MB/s. Learning something new every day...

Hello, I have built an Unraid server with a Gigabyte Z270M MB, i7 7700K and 16GB RAM. As I had a QNAP NAS before, I have backup my data on various internal HDDs. Now, I have created an internal array with 4 Seagate Ironwolf PRO 8TB HDDs (3+1parity) and a 2TB ADATA Legend 800 NVME as cache. I have connected 2 of my backup drives (Seagate Ironwolf PRO 4TB, NTFS formatted) and mounted them with Unassigned Devices and began transferring the data to the array. My issue is that the transfer rate started at around 150-160MB/s but after a couple of minutes it went down to 75-80MB/s and is capped there. I see that it only writes on the parity and the first disk of the array which I assume is correct (I'm an Uraid noob, so...). I also tried to change the primary storage from Array to Cache, it makes no difference. I was expecting a much higher performance, 150-160MB/s sustained transfer rate should've been OK. I'm attaching a couple of screenshots, maybe it helps.

So, I've (slowly) started to put together my new Unraid server and I'm not sure what the best approach will be. Long story, short... I have the following components: - i7 7700K - GA Z270M D3H (6SATA ports) with 16GB RAM - 2TB Adata Legend 800 NVME (that I plan to use as cache) - (for now) 4 x 8TB Seagate Ironwolf PRO HDDs - I say "for now" as I plan to extend these and get 8 or 10 HDDs in total - case (Node 804) and 600W Seasonic Gold PSU Now, I have also ordered a Dell LSA 9207i controller to be able to extend the 6 SATA ports from the MB. Is that OK to mix the usage of SATA ports from the MB and the LSA controller? I'm asking that because I read various conflicting info - some say it's fine to mix (4 HDDs on MB and 6 HDDs on LSA) while others say that's better to run all disks from similar controllers... the last approach would mean I'd have to buy another LSA controller if I want to have more than 8 HDDs in my array (I only want 1 array with 1 parity disk)! Thanks a lot!

Thanks for the answer. I decided to go a little bit different with the build since I have some other stuff around and will use that (for the moment, at least): - Intel i7-7700K and - Gigabyte GA Z270M-D3H (plus those 16GB DDR4) Both of them are solid performers - better than Biostar in terms of quality or Asrock/Asus N100M in terms of performance (if needed). At the beginning I did not think to use these due to a higher power consumption but I can lower the voltage and play around in the BIOS to reduce the i7 performance/power. Since the GA board only has 6 SATA3 ports, after an extensive search in the forum, I have ordered a LSI 9207-8i and the cables for it so 8+ HDDs won't be an issue. As for the license... I'm coming from QNAP, so I don't have an Unraid license - I need to buy one (Plus). Let's see the Cyber Weekend offers! 😁

Hello, As the title says, I want to upgrade my current setup and after some research I ended up with a couple of options. I'll start with what I have: - QNAP TS-451 (8GB RAM, Celeron J1800) - RAID5 (3+1) made out of 4 Seagate IronWolf Pro 8TGB - so a total of ~24TB available - lots and lots of documentation, personal photos (I'm shooting RAWs and I tend to keep everything), lossless music, and some 4K movies that I stream in my LAN via Plex (for media files, I'm not doing any transcoding or such) As my free space is running low - I still have 3.5TB free but with my photos and music it will be filled completely in the next 6-9 months - I want to move away from QNAP and build a custom NAS with Unraid, a solution that will allow me to add more HDDs in the near future. What I also have lying around is: - Fractal Design Node 804 with plenty of room for at least 8 HDDs - Seasonic 550W silent 80+ Gold power supply - 16GB DDR4 3200MHz RAM Option 1 (~370 EUR - I live in Europe): - Biostar B760MXC PRO 2.0, it has 8 SATA ports, - Intel Core i3-13100T (35W, tray) + cooler Option 2 (~230 EUR) - ASRock N100M with only 2 SATA ports - PCIe SATA X4 Card 6 Port Expansion Card for 6 additional SATA ports - from what I understood Unraid plays nice with the ASM1166 chipset (also, I think there are NVME to SATA adapters, but I could not find any - any suggestions here?) On top of both, I will have to add the ~80 EUR cost of the Unraid license. I'm more inclined towards the first option even if it costs more (the price difference almost covers an 8TB HDD) since I'm not a big fan of adding expansion cards. Also, I'm pretty sure both i3 or N100 will be able to drive my setup with ease since I won't do any CPU-intensive tasks (as I said, my media files are served only locally via the Plex server, without any transcoding). I'm not looking for my solution to be completely silent or to consume as little as possible. I'm mostly want to future-proof this solution storage-wise, by adding more disks, as needed. Any thoughts or suggestions? Should I wait for Intel U300/N300 integrated MBs to show up, would it make sense over the N100? Or, maybe, a 3rd option? Thanks a lot!
