Unraid ram drive. I want to eliminate the mirror and run in single mode.

Unraid ram drive My server really is only a NAS, so I want to give ZFS as much RAM as I can. I am looking to add a 3rd drives to the Parity Drive Set. Reply reply More replies More replies. I have seen a few guide that say put /tmp or /transcode and say put "- Unraid has a built-in shared RAM disk accessible under the /dev/shmfolder. But the board came with 128gb of ram and I currently don’t use more than 5%-10% of that. Am I best to make the If you want Windows to smoke, use a conventional SSD or RevoDrive for the OS, put 8GB of RAM in and use a software RAMdisk (I use Vsuite (free)) to store your Windows It was quite usable and file transfer speeds were very fast since it is obviously stored on RAM. I had some share settings set to Use Cache: Prefer or Only. That's when I stumbled onto flashing the H310 Hi there. Worked for a bit, then the phone said it lost connection, then the ipad lost connection and then the pc resumed playing . 2 to host Plex and its Metadata, an M. I used to have mine set up this way but without limiting transcoding RAM in some way, tmp will eventually fill up all available RAM completely especially if there are multiple transcoding sessions going on simultaneously. I have the unassigned devices plugin. My current system has a little more then 8G so maybe? Initially after doing that unRaid noticed all the SAS drives but parity sync was around 10 MB/s. I am looking to either add a 2nd new matching WD Black Gaming 6TB drive or add a 2nd 6TB WD Red NAS drive. How do i configure Plex to transcode to RAM/Array/Cache? A1. Edited April 2, 2018 by jbartlett Unraid is small enough that it all runs in RAM. RAM isn't subject to "burn out" from usage like an SSD would be, and transcoding doesn't need nearly as much space in Container in Unraid. Running 2VMs that uses 3GB ram each, crashplan backup, and tried 3plex streams, one to pc, one to iPad and last to htc phone. So recently I decided to upgrade the hardware of my unRAID server, since it is doing a lot more than I originally expected it would be doing after the last upgrade I made 4+ years ago and the AMD Ryzen sales looked pretty good. Click on the Main tab and select the devices to assign to slots for parity, data, and cache disks. Per the Unraid notes, ZFS is only allocated 1/8 or your RAM. Bought a used supermicro mainboard with cpu and ram. img location but nothing see I have once tried out a RamDisk program and installed a VM onto it. I saw in the Main overview of the Unraid WebGUI that it still produces writes on the NVMe where the docker image is located. Just not sure why only 1 drive is acting up out of 7 of those same drives For unRAID, I'm pretty sure it is stored in RAM, but I figure it's worth being clear that it's not always the case in Linux and can be on a physical disk. @Olivilo, Understand that Unraid is different than most Linux installations. This means that it has limited storage space in its file system. To be honest I always have struggled with fast network speed and drives using the default unraid pool config Reply reply. RAID0. Storage Management. Note that the Unraid boot process unpacks Unraid binaries from the archives on the USB drive and then Unraid runs from RAM, and during normal running there are only a small number of accesses to the USB drive relating to configuration information. This shared RAM disk defaults to half of the total system memory, which should usually be more than enough for a few I cant say that this will work for every flash drive, but I was just able to convert a new Verbatim 16GB USB2 drive that I took a chance on (it came as MBR) using Diskpart in windows 11, run as administrator. When not using Unraid as an application server or virtualization host, the RAM is solely used to load the Unraid operating system from the USB drive at boot. I believe that most distros will also move /tmp to a physical disk if it grows too large compared to your current RAM usage. It is actually installed to a RAM 'disk' rather than on a physical drive (ssd or hd). I bought a Ryzen 7 2700, Asus ROG STRIX X470-F GAMING, 16GB DDR4, and As I have installed 32G RAM it seems that /dev/shm is limited to the size of my 16GB USB flash drive, correct? By that it would be possible to use /dev/shm/PlexRamScratch without the need of an additional script. There seems to be some information on how to do this, but I could not find any method that Q1. It works fine on unraid. it frees the one drive for data. It was quite usable and file transfer speeds were very fast since it is obviously stored on RAM. tv <-- Click that link to launch the The best way to ensure you dont have a drive that will fail within the first days is either a full format, sector by sector, or, in case of UnRaid, the pre-clear. You want to map /dev/shm on the host to /t You can do this by allocating space in /tmp/. Thank you for this, it seems to work in a quick test with 6 transcodes (3 4k and 3 1080p), will leave it this way for a while and see if everything keeps running smoothly The ram is $32 per module with needing to buy 2 at a time due to dual cpus So i'm looking at making an unraid nas/media server at the end of the month and I was wondering how much ram it would require. The Linux kernel keeps the most recently accessed disk buffers and directories in The folder caching (cache_dirs) reads directories continously to keep them in memory. I've done it to move massive files over the 10gb network and fully saturate the line. Assigning devices to Unraid is easy! Also: here is a detailed write up on fast file transfers (10g+) on unraid, how to optimise, cache SSDs, RAM usage etc Reply reply [deleted] • I would use ZFS to better use the cache available in your system. The program does not know whether a directory is already in memory or need to be reread from disk. The server used for testing has In Unraid the RAM is pretty much usless its sits at 1% utilized and i think thats the minimum that the dashboard can display, I think once I've seen 2% used. Assigning devices to Unraid is easy! Just remember these By moving transcoding to RAM, you alleviate the burden from your non-volatile storage devices. Since / is a RAM drive, this is valuable ram that my service can't use - correct? So I'm thinking of upgrading my system to 8GB of ram. I want to eliminate the mirror and run in single mode. I set the one drive that has been throwing errors to no spin down to test this out. Unraid has a built-in shared RAM disk accessible under the /dev/shm folder. Old Cache drive SSD 1T I added a second drive to the cache pool nvme 2TB Raid1, And let it clone it self. RAM disks really arn't a use case for Plex unless you have some spare ram around and are worried about your core HDD failing from to many read writes. I do believe after moving, unRaid deletes empty folders in the source-disk. Pool TWO has 2 drives in raid1. All I had to do was Which means you would have enough RAM available to store all of your stuff for the containers, have something for everything that is running on your unraid, unraid itself AND have even more to spare when you copy more onto the drive. I'll be retiring this drive from my main server and using it for platter heat map test where the entire drive is read and a heatmap of the read speeds given. There is very little wear on the USB drive, so most people run it for years off the same stick. I recently decided to stop booting from, and writing to, the usb flash drive after two drives has gone bad. I built my box with 4Gigs of RAM - and now I'm starting to do more and more with the system and my / is starting to get larger and larger - 1. 1. I tried pathing the vdisk to the cache drive I also tried pathing the libvirt. unraid. 2 for cache, 4 drives (1 parity 3 media). I do believe unRaid (with some settings) delete empty folders on array disks after moving, but it doesn't delete empty folders that we, the users, have left there. Is it better to copy the data to another drive and wipe both drives? The system did hang during one of the BTFS balance check but this was actually when it was checking another pool not this one. The optimal way might be to create your own I'm running an unraid OS with plex if that helps. Only downside is a lack of persistence In order to increase performance, I'm looking to feed it with: - a large RAM disk (my server has 128GB).

And if you just backup the USB, you can reinstall onto a new one and be up and running in minutes if it ever does die. Yay I finally maxed out my Unraid mobo today: max ram capacity, best CPU it can handle, every SATA port used, every PCIe lane in use Upgraded to an 18 TB Drive. Edit the configuration of your Plex container and add another path. The disadvantage that a RAM Disk has is how the RAM handles data, as soon as there is no power supplied to the By this guide Plex uses your RAM while transcoding which prevents wearing out your SSD. However, if you are building a system with recent components, you might not even be able to find any compatible 2 GB sticks of RAM. g. Spinners should have a steady decline over the entire range of the drive. 2 Gigs now. Below are the different options for setting transcoding for Plex and Plex Pass:- Transcode to RAM - create a new volume mapping, host path /tmp and container path /transcode then define TRANS_DIR so that it points at ram drive e. category5. At this stage i'm just wanting to set up ram drives on my Win10 HTPC and my unRaid server to check out network transfer speeds of my 10gb cards, (and keep hdd speeds unRAID automatically creates a RAMDISK on 50% of the total available RAM, it‘s available at /dev/shm - the safest way would be using that. Identify memory problems in situations where a restart is not (immediately) possible or just stress test your RAM. The only downside to a Disk on RAM is that you have to ensure that the host To assign devices to the array and/or cache, first login to the server's WebGUI. I have no idea if such a thing already exists, but as a coder, I don't mind just making one myself. Therefore it cannot avoid spinning up disks when it happens that the linux memory cache evicts a directory and cache_dirs rescans the directoy. Here is to more great years of Plex upvotes I've created the first beta of a web-based array capacity calculator. With Viewing Drive 5 by itself, I can see it's curve is not normal. A diagnostic plugin that lets you test your RAM without needing to reboot. It would be nice if Unraid could use RAM as a cache drive or a second cache for file transfers and/or docker/VMs. - Shutting down server and putting USB Unraid boot drive into my PC. . Total ram 16GB. Running a home assistant VM, Jellyfin and *arr stack, paperless ngx and adguard home on unraid right now. System is running fine and I think cpu wise I use what I have, with a bit room to grow. Looking at this thread I was thinking of adding more RAM to one of my HP N54L servers to help cache writes, but I was trying it first on my test server and Unraid uses a very small amount of RAM for cache, I’d like to totally cache files up to 8GB, according to my tests I would need almost 64GB of RAM, N54L max RAM is 16GB. yesterday when i finally got the time to play with my unRAID server i saw it behaving weird, and over the last 24+ hours it has been reformatted, had new usb drive installed and so on and still - very unstable and weird behavior. And trust me, you want to run the preclear, wait the 24h and not be upset about yourself Hi, Long time reader, first time poster. Saoshen Unraid, an M. The Unraid install is tiny- there's no need to So a couple of days ago i received my RAM upgrade, 64GB of joy I installed it an went on doing other stuff. cache_dirs is a script to attempt to keep directory entries in memory to prevent disks from spinning up just to get a directory listing. PC Specs: i7-10700 CPU (Using quick sync) 24GB RAM. I would be starting out with a 10TB drive, Plex, 1-2 VMs, and whatever i find interesting in docker while adding a 10TB parity drive in mid October. This shared RAM disk defaults to half of the total system memory, which should usually be more than enough for a few Plex transcodes. Not possible. I hope a update comes to undo/fix this, as editing each drives power settings (at least what I understood from the linked topic) does not sound like something i wanna do just for fun. While doing my googling there was a mention of a kernel bug a few years ago that if system ram was more then 8G it disables the write cache. I don't know why that happens. cpu and ram usage 99% So I currently have two 6TB WD Black drives set as parity drives and all is working well (though the WD Black Drives run hotter than I prefer). How is one supposed to remove a drive from a 2 drive cache pool. My original RAM is DDR3 1333 Unbiffered ram By this method Plex never uses more than 4GB RAM, which is important, as fully utilizing your RAM can cause an unexpected server behaviour. To assign devices to the array and/or cache, first login to the server's WebGUI. I also have 64GB RAM on my server but have limited transcoding to using 16GB RAM. :- TRANS_DIR=/transcode /transcode This could be a problem. Live Memory Tester for UNRAID. Afterwards I tried to enable docker and VMs only to find neither of them would work.
