Unraid ram drive 248-1. Live Memory Tester for UNRAID. Right now a transfer from my Unraid to my new PC build with an NVMe drive I RAM = system memory usage of his 16GB Log = amount of disk space used of the max allowed for unraid logs Flash = Unraid USB stick space usage Docker = how much of the docker. All I had to do was To Cache drive or not to Cache Drive On an unRAID server with add-ons, more RAM can be very beneficial. Posted May 1, 2020. Edited December 23, 2021 by nickp85. cpu and ram usage 99% I've created the first beta of a web-based array capacity calculator. don't about the caching, its normal unused memory is wasted memory. 0 stick, all you will save is about 10 seconds of boot time and that's about it. 9. This shared RAM disk defaults to half of the total system memory, which should usually be more than enough for a few By this guide Plex uses your RAM while transcoding which prevents wearing out your SSD. Unlike most server hardware, speed is not a primary concern for Unraid, as it runs from RAM once booted. I had a quick question. Total ram 16GB. Edit the file /boot/config/disk. They have proven to have significantly longer endurance than even the manufacturer ratings in most cases, and even with the added I ain't no tech genius but shouldn't "use cache disk: Yes" mean that the shares end up ON the cache drive? Because I've done all according to the guide but when I browse /mnt/cache in the Unraid GUI, the only folders I see on the cache drive are my system and appdata folders (amounting for 61GB). 12. tv <-- Click that link to launch the calculator. 2) and Virtio Drivers 0. And trust me, you want to run the preclear, wait the 24h and not be upset about yourself 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. Disks are missing Disks are unmountable Disks are read-only Disks have read errors Current setup: Case: SilverStone CS380 [disks are now connected to a SATA backplane] Motherboard: Gigabyte GA-Z97-HD3 CPU: Intel Core i5-4690K RAM: 32GB DDR3-1866 CL10 (Kingston HyperX Fury 4x8gb) [changed from 2x8gb Corsair Vengeance LPX] PSU: Solid Join the conversation.

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. I have tried different RAM, mainboard, USB stick, BIOS settings for RAM (3200 / 2133) updated from 6. More RAM means more caching and as RAM is even faster than the fastest SSDs, this adds additional boost to your SMB transfers. unraid. Put back into old (Spare) and again now seeing random failures of disks. Running 2VMs that uses 3GB ram each, crashplan backup, and tried 3plex streams, one to pc, one to iPad and last to htc phone. Running our own quick benchmark test using XBench on a Macbook Air showed that write speeds for a RAM Per the Unraid notes, ZFS is only allocated 1/8 or your RAM. It works fine on unraid. These archives are unpacked fresh at each boot into RAM, and the OS runs completely in RAM. When you state, "After a few hours my cache drive kept filling up", what does that exactly mean? The Unraid OS doesn't install to any of your storage. I recently swapped out the E1200 for a Celeron 430 since I had It's not difficult, but there are a few steps that involve editing a file on the unRAID USB boot drive, restarting the server, then re-mapping the transcode folder to the RAM disk in Plex container settings. For example, if you add a Windows 11 My unraid GUI is missing the array devices and cpu/ram info - but the server is working fine - and docker is also working. Transcoding to RAM is a waste of RAM, which was in turn a waste of your money to buy more RAM than you needed. There is no need to transcode to RAM anymore and hasn't been a need for years. @Olivilo, Understand that Unraid is different than most Linux installations. Currently I have a 20TB Unraid server with 32GB of ECC memory and a 256 GB SSD cache. That's when I stumbled onto flashing the H310 I have once tried out a RamDisk program and installed a VM onto it. trurl. Also my MB was running BIOS V3. But I am getting ready to migrate it to a new 24 drive case and add 12TB more of drives to the case. I was aware of /dev/shm only allocating half ram but I was under the impression that /tmp would be able to see and use all available ram, an So a couple of days ago i received my RAM upgrade, 64GB of joy I installed it an went on doing other stuff. I've been using an Intel DG965R board with an Intel E1200 (dual core Celeron) with 2GB DDR2-800. You can post now and register later. I installed 64 gigs DDR5 RAM to support ZFS, but it seems to be barely using my RAM. I went about Container in Unraid. Bought a used supermicro mainboard with cpu and ram. even when all Disks seem to read just fine, so why it's so slow to copy data between disks on UnRaid when it's not with other OSs? Edited June 17, 2021 by jbssm mark as solved Quote; JorgeB. img location but nothing see 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 A few days ago I had a power outage. It is actually installed to a RAM 'disk' rather than on a physical drive (ssd or hd). 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 Storage Management. Therefore it cannot avoid spinning up disks when it happens that the linux memory cache evicts a directory and cache_dirs rescans the directoy. 00:14. The only downside to a Disk on RAM is that you have to ensure that the host 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 You can do this by allocating space in /tmp/. The boot flash also stores all of the settings from the webUI (your configuration) so these can be reapplied at boot. 8 GiB) I have multiple Dockers (Not been a issue before adding new VM's) My VM's 2 x Windows 10 = 6144 MB = 12G 1 x pfSense = 3072 MB = 3G 1 x Hassio = 2048 MB = 2G 1 x Xpenology = 8192 MB = 8G Total: 25G Docker 38% of 62. Saoshen Unraid, an M. I am running a server with 50+ drives, is there a good way to ID a disk so i can keep track of which drive is which? They are all just Disk 1, Disk 2, etc and sba, sbb, sbc, etc. The program does not know whether a directory is already in memory or need to be reread from disk. Reformatting the cache to new partition alignment and hosting docker directly on a cache-only directory brought writes down to a bare minimum. It turns out the USB drive was bad. Certain operating systems for network-attached storage, for example, TrueNAS CORE, require a lot of RAM for smooth operation. After the brand new drives disappeared I did try upgrading unRAID from 6. How is one supposed to remove a drive from a 2 drive cache pool. 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). There seems to be some information on how to do this, but I could not find any method that 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. Quote; trurl. Ensure you install this driver or later as well as Unraid 6. Identify memory problems in situations where a restart is not (immediately) possible or just stress test your RAM. 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. then all you need to do is use krusader or some other type of file browser system to shuffle files from the drives you want to remove to the keepers and just do the ' new config thing and keep no assignments ' and then add/remove as Running 6. Disk-based Linux distributions often use swap space but unRAID runs entirely in RAM and doesn't use swap space by default. With 1TB cache with 2 500GB M. Have a mostly Seagate IronWolf and I don't know why that happens. The optimal way might be to create your own I'm running an unraid OS with plex if that helps. Certain add-ons, such as torrents and virtual machines, will run much quicker with more RAM. Max. The flash drive holds all your basic server configuration information in the 'config' folder on the flash drive. 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.

Unraid has a built-in shared RAM disk accessible under the /dev/shm folder. There is very little wear on the USB drive, so most people run it for years off the same stick. 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. 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 I'm trying to optimize my N40L server for a large WORM media storage array. Per the Unraid notes, ZFS is only allocated 1/8 or your RAM. abuse the system and see how big the transcode folder gets, then add 10-15% and go back to using a RAM drive that is at least that large assuming you have enough RAM. I now have 4x1TB and 5x500GB drives attached. Edit the Plex Container and enable the "Advanced View": Add this to "Extra Paramet #Limit PLEX Transcode RAM Drive Size mkdir 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. category5.

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. 0 stable version. Possible Use-Cases: Parity protection and a degree of corruption detection/repair for custom-mounted (e. 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. I am looking to either add a 2nd new matching WD Black Gaming 6TB drive or add a 2nd 6TB WD Red NAS drive. 1. Everything se 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.
