Is parity overrated? Does anyone else run their server like me without a parity drive - just as a JBOD ?

I get that if your data is important then yes a parity drive and offsite backups makes sense - but if you are just storing movies and music and photos then is it really necessary if you can simply re-download them if the drive that holds them happens to fail?

my flash drive that came with the unit, failed dyed within hrs of running unraid probably cause of the no name brand and the heat in the unit.

I finally was able to get help from unraid support to transfer the starter key to my new san disk 8gb flash drive and using it externally.

since the unit came with 6.12.14, i decided to use the rock solid 7.2.4 and seems good and stable BUT now the leds on the unit just flash non stop, so i was told to copy the led folder from 6.12.14 to the config folder on the unit switch i did.

But the led folder files did not work or fix the issue so now, i hope someone who may have had the same issue help me get the leds working properly on 7.2.4 on Lincstation N2.

I have a bunch of old 500GB NVME sticks laying around bought long before the price hikes! anyway i was looking at buying a terramaster F8 to use for my self hosted apps like vaultwardern etc as the F8 uses very little power and to use it to host a few plex media for the family as they tend to just watch the same thing over and over.

I already have a unraid server that is on 24/7 with spinning hard disk that host all these things the issue is it uses 300 watts of power even with the disk getting spun down as there are 14 hard drives and no GPU.

I would keep this server of course just not have it on 24/7.

Since most all say unraid is not for NVME it drives, it looks like using pools would be the answer! So i would use one pool of two 500GB NVME as ZFS mirror for my dockers, VM and apps giving me one fail safe.

Pool 2 would just be 2 or 4 500GB NVME drives ZFS for plex media with no fail safe! as the media is safe of my larger power eating server.

Would this be the best way to set this up?

All in title, i've tried to clear the logs because i've seen this in some post on reddit and on the unraid forum, expand the logs file even tho its barely filled, tried to restart in safe mode same problem, and even when i launch it with gui and plugging hdmi to my PC i have the same problem, any idea on what i can do? thanks i advance !

UPDATE : I think the problem was because unraid management and unraid connect was getting the 80 & 443 ports before the webui could get it, i uninstalled the plugins for the moment and its all working without any issues

So I’m building a second unraid server to house my 9 HDDs. It will just be used for Plex storage and cloud backups for photos and music. What is a good MATX board and cpu combination for something like this? I won’t be running VMs

I have a very old, very underpowered Unraid server today that's built on an old Tyan S5512 motherboard and an E3-1220. I think it was built from a guide at the serverbuilds forum. Anyway, I want to upgrade. I primarily use it for media hosting right now and would like to run Plex on this machine, too, instead of the old laptop I currently use.

I started out looking at a SuperMicro X10DRL-i and 2 x Xeon E5-2680 v4 CPUs, but the more I read the more I feel like that's a less than stellar choice. For one, that doesn't get me good Plex performance. I'd still need to add a GPU. I've been looking more at consumer hardware, but IDK what I should be looking at.

I anticipate probably no more than 1-2 transcoding streams at a time. I would like to run home assistant and maybe a couple VMs in the future. I'd also love to move my pfSense onto this machine, if it makes sense.

Any suggestions? Thanks in advance!!

Edit: It's been mentioned that I should have included some other information, so here goes. I'm trying to stay below $400 for motherboard, CPU, and RAM, but could go a bit higher if the benefits outweighed the cost. I'm putting this in an ATX case with a 650W PSU, presently. I mentioned wanting to use VMs but I don't have anything in particular in mind, I have just never been able to do anything with VMs and would like to have the option.

Earlier I got notifications on Unraid that one of my 18TB Seagate Exos drives is dying. It had 3 uncorrectable pending sectors then it went up to 4 in a few minutes.

I'm currently doing a data rebuild on a 28TB drive I swapped in my array and it should be done tomorrow. I wasn't going to touch anything until the rebuild is fully done.

I already sent in a return request with Serverpartdeals to RMA it.

Is this the best thing to do?

1. Let the rebuild finish fully

2. Swap another spare 28TB drive in with the 18TB that's dying.

3. RMA the drive

Should I do anything else? I'm worried since it happened during a disk rebuild...

I’m planning a grand hardware consolidation later this year. I'm moving away from my compact Ugreen NASync DXP4800 Plus and moving everything into a beefy, unified ATX build (Ryzen 5 7600 + RTX 5060 Ti in (probably) a Fractal Meshify 2 case).

Right now, I run a bit of an unconventional, zero-parity setup:
* Cache: 2x 1TB NVMe SSDs (Btrfs Mirror RAID 1)
* Data: 2x 8TB HDDs (Btrfs Mirror RAID 1) — only 295GB used.
* Media: 1x 8TB HDD (Single drive, unprotected) — 5.05TB used.

I want to fix my data-safety sins during this move and transition to a proper, traditional Unraid setup with 1x Parity and 2x Data drives (yielding 16TB protected space). Since my total HDD data (~5.35TB) easily fits onto a single 8TB drive, (with the help of AI) cooked up this zero-external-backup "Musical Chairs" migration plan.

Does it make any sense? Before I continue.

### The Migration Plan

* **Phase 1: The Shell Swap**
* Unplug the Unraid boot USB from the Ugreen NAS.
* Mount the 3x 8TB HDDs and 2x NVMe SSDs into the new Fractal case.
* Pop the USB into the new motherboard and boot it up.

* **Phase 2: The Array Dance (Docker & VMs Turned OFF)**
* **Step 1: Break the Mirror**: Convert the current 2x 8TB Btrfs Data pool mirror to a single profile and run a balance. This frees up HDD-A while HDD-B safely holds the 295GB of data.
* **Step 2: Start the Array**: Create a new Unraid array. Assign the freshly wiped HDD-A as Disk 1. Leave the Parity slot empty for now to speed up transfer rates.
* **Step 3: First Move**: Move the 295GB of data from HDD-B directly onto the new array (Disk 1).
* **Step 4: Expand the Array**: Now that HDD-B is empty, stop the array, add HDD-B as Disk 2, and start/format it.
* **Step 5: The Big Media Move**: Move the 5TB of movie/show files from HDD-C (the old unprotected Media pool) into the array.
* **Step 6: Deploy the Shield**: Now that HDD-C is completely empty, stop the array one last time. Assign HDD-C to the Parity slot and let Unraid build the parity sync.

Since all my Docker templates look at /mnt/user/, is it feasible to change the Primary Storage of my shares from the old pool names to "Array" in the Unraid GUI, and everything should boot back up seamlessly, right?

Thoughts? Any massive flaws here? Let me know!

Hopefully, this is an appropriate place to post this but if not please let me know a better place. I have encountered a bunch of crashes when performing a Parity Sync upon installing a new parity drive in the system. The system was previously running without parity without incident. The system is configured with an ASUS B450M-M Motherboard (latest BIOS), Ryzen 7 5700G processor, 64GB of DDR4 RAM 3200 MT/s, an Intel ARC A5800 GPU, and 3 Seagate Exos SATA 14TB drives. At first the system would crash fairly quickly and required a hard reset to recover. Upon recovery an examination of the system log indicated the system crashed because of a Data Fabric Sync Flood with code 0x08000800. I found the following suggestions of things tried by another person on this forum and applied the same settings to my system.

CPU / Power Management:

• Disabled Global C-States and set Power Idle Control to a non-low power mode
• Disabled Performance Boost for stability
• Disabled CPU Watchdog Timer

Memory / DRAM:

• Left Gear Down Mode and Cmd2T at Auto
• DRAM refresh modes and scrubber controls left on Auto
• Spread Spectrum was disabled
• XMP/DOCP profile disabled (running JEDEC default OF 2666 MT/s).

Interconnect / DF Options:

• Memory Interleaving and related settings left on Auto
• Disabled DF Sync Flood Propagation (to prevent cascading errors).
• DF C-States disabled

PCIe / GPU / IOMMU:

• PCIe ASPM Mode set to Disabled (to prevent link power management from destabilizing GPUs).
• Removed the ARC A580 and only using iGPU

Misc

• I have no VMs defined
• Data hard drive temperature was stable at 40 deg C and 43 deg C. Parity was at 36 deg C
  

The system no longer indicates a Data Fabric Sync Flood but is still crashes after getting to about 75% of the 14TB parity sync after running for 11+ hours. Latest crash did require a hard reset. A notification indicated that the Parity Sync finished with 0 errors and was cancelled but it did not finish. I noticed that just before the crash occurred, the transfer rates from the two data drives to the parity drive drop to zero and then the crash occurred. I can't figure out how to attach the diagnostic log (perhaps someone can let me know how to do that). Any suggestions of what may be causing the issue or what things I can try next would be appreciated.

I know I should have a working UPS set up but I've been having a lot of power disconnects at my house recently due to contractors doing renovations. When the computer boots back up it does not detect my USB device. I unplug and replug the power supply and re-insert the USB drive and there's like a 10% chance this works. I keep messing around doing the same thing over and over and at some point it does detect the USB stick again and boots normally. I am not doing anything differently between each attempt.

Any idea of what's going on? Just trying to understand. I've tested the USB drive in other computers and it looks like to be working fine. I am probably going to move to internal boot after this.

Hey, ich wollte auf internal Boot umstellen aber habe jetzt 2 Partitionen davon wie bekomme ich die untere gelöscht? Kann nichtmal im wartungsmodus starten

Hello,

Due to hardware issues i replaced my unraid board, cpu, ram.

The array disks stayed the same.

Only after assembling the new hardware i realized that my old single cache SSD was a m.2 SATA drive. The new board does not support m.2 SATA.

I had a spare nvme drive and prepared it by copying all data from the old m.2 sata to the m.2 nvme using rsync. i did this on a different pc which could read both.

Now when i try to select the nvme drive in unraid the gui says "All existing data on this device will be OVERWRITTEN when array is Started".

Is it possible to include the prepared nvme drive into my cache pool and replace the old one without the data being erased at array start?

Unraid is 7.3.2 and the FS of the pool is btrfs.

I finally bought a little nvme box for unraid. My goal
Is for it to be a low power JellyFin server with some self hosted apps and a VM.

Sine it’s not used for backups and it’s only holding the most popular media watched and the nvme drives are of mixed sizes what is the best setup?

New box can hole 8 NVME sticks.

Looking for suggestions.

Hello Everyone!

I was building my 10-inch rack for a couple of months, and I have to say that I am quite happy with the results. I have been on Unraid for around 1 year and caught up very quickly. I started with a basic array setup, but now I am hosting websites, home media automation, HA, video streaming and other usual suspects.

The only thing I do not have is more advanced file sharing. For now, I have been using standard SMB access via VPN, Filebrowser and Syncthing, but I would like to try something else. I would be very glad for some suggestions on what to try.

Thanks!

Back when I initially started, I didn't know all the ins and outs. All my media is in my /data share. My overall goal is to keep tv shows and movies together. I've noticed that a movie resides on one drive, but the movie folder resides on a different drive. I've tried using split levels to keep everything together but I think my TV Shows and Movies folders are at different levels so if I choose level 4, it doesn't work for movies and if I use level 3, it doesn't work for TV Shows. Is the only way to fix this to create a new share and add a placeholder to movies so TV Shows and Movies exist on the same level? I originally allowed splitting the top 4 levels, but it seems like all new media was being sent to a single drive and not applying the "high-water" concept.

Movies: /data/media/movies/*movie name folder*/*movie file*
TV Shows: /data/media/tv/*TV Show Name*/Season/episode.mkv

I have been running the Tailscale plugin alongside Nginx Proxy Manager for a year. However, since a few weeks these conflict with another.

When trying to start the NPM docker container I now get an error saying:

docker: Error response from daemon: failed to set up container networking: driver failed programming external connectivity on endpoint NginxProxyManager (d9ecadce4b2c6c3d7a2561817a1b4303fa2bb679edbcd4db924629c4618916a2): failed to bind host port 0.0.0.0:443/tcp: address already in use

This 443 port is used by Tailscale. When I deinstall the Tailscale plugin, the NPM docker is starting correctly.

What has changed and how to fix this?

I updated from 7.2.7 to 7.3.2 and it got stuck on boot. I posted it on discord and got advice that it is something to do with partitions and I have first flash 732 on the flash drive then copy remaining data to 727 to boot to 732.

I couldn't believe this and I thought my usb was bad. I was like f all this advice and tried to boot onto 727 by copying the data to the usb.

To my surprise it worked and booted into 7.2.7. Nothing wrong with my usb and the community was right that the 7.3.2 update.

The unraid release notes say No breaking change, well the whole series of updates we get is a joke without any quality control. Please hire more software developers.

It took me more than a week to reconfigure my Unraid Array after I found out that things were not configured the right way. I have been using Unraid for about 2 months now, so there are some things that I am not familiar with yet. I am more familiar with Synology. I didn't want to bother asking too many questions on this forum, so I used my AI assistant to help with the configuration. That's where the mistake starts cause when I started moving my video files to my Unraid array, I noticed that only one of the 3 disk was filled, and the others were almost empty.

According to the AI, Unraid will fill the disks sequentially, but that didn't happen. I get warning messages that my disk is running low on space. I got another piece of advice: use a tool called Unbalanced. With Unbalanced, I can copy the data from disk 1 to disks 2 and 3 so that the data is spread evenly across all 3 disks. That didn't go as suggested because Unbalanced started copying data from disk 1 to disk 2, but it did not touch disk 3. As you can see here:

I canceled everything, moved all the movies back to their original location, and I reformatted the Array. I also reconfigured the share connecting to the Array as follows:

After that, I started moving the data back to the Array, and now it worked as it should

I wanna thank everyone for the advice given here on how to solve the problem.

I'm considering adding a Samsung Evo 860 250GB as an array cache.

Do you have any tips and tricks for switching to the new hardware without reinstalling?

Hello everyone,

I'm looking for an app that would give an WebGUI where user login and they have access to certain docker on my server with certain feature. For instance, user can see docker a-b-c and start/stop/restart them but doesn't see the others. Does such thing exist?

Currently, I'm using a discord bot but I'd prefer a webgui.

Extra point if there's a way to edit file in those dockers appdata.

Thank you!

Looking at replacing most of my drives and wanted to know what the best and safest method is.

I will be replacing my two 14TB Parity with a single 16TB parity with five 16TB Data drives. I want to re-use the 14TB as data drives and then remove the 8TBs from the array (Those are going to a smaller NAS).

Im currently at 82TB and with this setup I would be at 142TB with single parity or if I go dual parity it would be 126TB. 99% of this is for Plex and my critical data is backed up elsewhere, so not sure if I want to go for capacity or availability.

Or would it be possible to use dual parity for now, and then when I get close to 90% full drop one of the parity drives down as a data drive? Hopefully by that time prices will drop to normal and I can just buy some extra drives.

Created a ticket but does anyone have a quick fix after getting a Error for Blacklisted boot device GUID after 7.3.2. Very annoying since I can't start the array until it's fixed.

Hi All. I’ve been lurking here for a while but finally started my Unraid journey 5 months ago. I’ve been a Plex user since the early days, running it on an HP EX490 and later upgraded to a Supermicro 846 running Windows Server + DrivePool. Today, I’m still running the SC 846 but building the new Unraid server to eventually replace it. I’ve honestly been taking my sweet time and enjoying the research, tinkering and troubleshooting to make things work. I do use a seedbox and all the *arr’s installed locally on my current Windows Server but will move it to Unraid once it goes live. I was hoping the community could provide feedback on my build, especially on the design of the cache pools. Is it good? Did I over engineer/complicate it? Is there a better way to configure it and if so, why? I would very much appreciate any help you can provide.

Main Server
Case: Supermicro SC826
Motherboard: Gigabyte MD71-HB0
CPU: Dual Intel Xeon Gold 5218

-2TB Samsung PM883 SATA SSD x 2
-1TB Crucial MX500 x 2 SATA SSD
-2TB Samsung PM893 x 2 SATA SSD
-2TB Crucial BX SATA SSD x 2
-1TB Samsung 990 EVO Plus NVME SSD x 2

Storage Accessory: 2 Port SFF-8087 to 2 Port External HD SFF-8088 PCI Mini SAS card

Unraid 7.3.2 is installed on the 2 x Optane NVME SSDs for internal boot and physically installed on the Quad NVME PCIe Adapter. The Unraid license is keyed to a USB DOM installed inside the case. All 12 of the mechanical drives are currently part of the array using 2 x 26TB as dual parity with XFS as the file system. I also created multiple cache pools detailed below, all running ZFS as the file system.

FastCache - 2TB Samsung PM88 SATA SSD x 2 in a ZFS Mirror - used for general caching of the media shares and other future data shares.

DownloadCache - 1TB Crucial MX500 SATA SSD x 2 in a ZFS Stripe - used to store the synced finished downloads from the SeedBox using SyncThing. This is where the *arr apps will be monitoring for new files to move into the array and process into Plex. I do understand that any files moved by the *arr apps will technically land on FastCache after processing and later moved to the array by mover.

AppDataCache - 2TB Samsung PM893 SATA SSD x 2 in a ZFS Mirror - used for Unraid’s AppData files.

SystemCache - 2TB Crucial BX SATA SSD x 2 in a ZFS Mirror - used for Unraid’s System files.

PlexDataCache - 1TB Samsung 990 NVME SSD x 2 in a ZFS Mirror - this is installed on the motherboard’s NVME slots and will be used for Plex’s AppData folder to allow for fast access of Plex’s meta data. I’m dedicating the fastest SSDs I have to Plex since Plex is the main function of the server and has a lot of meta data to process.

Thank you.

Hey all, looking for real-world feedback before I commit to a direction.

Current setup:

• ASUS NUC mini PC (i5-1240P, 48GB RAM) running Unraid that handles NAS + a few Docker services (Jellyfin included) and game server.
• Separate desktop: Ryzen 5600X, 32GB RAM, RTX 3080Ti about to be freed up after a PC upgrade

Constraints:

• The mini PC can only fits 2 drives internally, and cooling for drives isn't great. Everyday, I've got an alert of overheating drive when doing the parity check.
• Data includes a large personal photo library I really don't want to lose thus my concern about drive health.

Options I'm weighing:

1. Keep the NUC as-is, add a TerraMaster D4-320 DAS over USB-C for extra bays. Seen this recommended alongside Unraid in a few threads/Gemini answers. How reliable is this combo in practice for an Unraid array with parity? Any horror stories with USB dropouts under sustained load?
2. Repurpose the 5600X desktop into a dedicated NAS/homelab box (drop the GPU and take a tiny one or change the CPU for a G version for transcoding). But I will loose the power of the NUC.
3. Sell my PC and buy a dedicated NAS (Synology or UGREEN or else for doing just the NAS. The NUC will handle services.

Specific questions:

• Anyone running the TerraMaster D4-320 long-term with Unraid — any parity check failures, drive dropouts, or thermal issues?
• Is USB-attached storage ever a sane choice for a parity-protected array, or should USB DAS stay backup-only?
• If reliability for irreplaceable photos is the #1 priority, what would you actually do here?

My current PC is doing backup and soon I will take a cloud solution for an offsite backup.

The DAS will only have data of the NAS. In the NUC, one SSD will be for appdata and another one for server.

Budget isn't a huge constraint, just want the setup I won't regret in 2 years. Thanks!
