When are we going to be able to move off using highly unreliable flash media for our servers? Surely there must be a way to switch this over to an SSD? It's rather draconian and i've been through a few flash drives on my server

Very nice work guys. When are we going to be able to ditch using a USB flash drive for unraid, and move over to something more reliable as a boot device? It also makes it a royal pain to virtualise unraid (i know this isn't technically supported)

Correct, assuming you're copying from the cache drive before the mover has ran or copying to the array for the first time and hitting the cache disk.

imo, 10Gb networking isn't worth it on unRAID. You're limited by the speed of a single drive. For that many disks and speed seemingly important to you, i would be looking at a different solution personally. If sticking with unRAID, then it's madness to purchase all 20 drives in one go, unless you already have a ton of data to copy over and use the space. If not, then the best thing is to purchase a couple (of mechanical drives), and when they are approaching being full, purchase more at what will likely be a lower price (and possibly higher capacity drives). This is one of unRAID's main strengths and what it excels at, along with an excellent and user friendly docker experience

On a completely different note, it's worth going through https://www.albumartexchange.com and downloading super high quality artwork to all your FLAC files. I did this, took me a good couple of weeks but it was well worth it!

Sorry, i meant to say Airsonic Advanced (which is a fork of DSub) This should allow you to stream around your home too - not done it myself but i would be staggered if you couldn't via chromecast etc

thanks chaps, ill take a look!

You can use Dsub via docker. It can be configured to direct stream FLAC without reconverting to MP3. I've used this before for my 1.2TB FLAC collection

Yeah i regularly run the file integrity plugin, this is part of the reason i'm switching to ZFS for my main data storage, and using unraid for less important data / backups and using docker etc

Hey Chatnoir, thanks for the reply As far as i'm aware(!) i've not had any file system corruption (but this worry is why i'm switching my data to TrueNAS). I'll check the lost and found directory, thats a good idea I only copy into shares which encompass all the disks. I did search every drive one by one looking for the movies and they are indeed gone Very odd and a bit worrying. I'll check my main blu ray folder later which i'm dreading as i've over 2000 movies in it (hopefully!)

Morning all Bit of a weird one. I'm just in the process of migrating all my data from unRAID to TrueNAS (keeping unRAID as my backup server), and i'm copying all my files over the network. I have various movie folders i.e '4K Movies' with all the movie folders within containing the movie file. I noticed that around 40 of the 600+ movie folders i have are completely empty, for what seems like no apparent reason. I would not have deleted the files in these folders, and i'm baffled how this could have happened. I've checked log files etc and nothing is showing with regards to any of the movie file names (so i don't think the log files would help) I've checked all disks and shares are active (so no folders are being excluded from the network folder search), and consequently checked the contents of each folder a disk at a time using FileZilla, and of the movie folders in question are indeed empty (seemingly randomly) I also checked the recycle bin, and nothing is there. Sorry i'm probably not providing any more info, but just wondering if anyone has experienced anything similar? I would consider myself as a fairly "advanced" unRAID user and its generally been pretty solid thanks

I'm not convinced that trim is working the way it should be. I have two nvme devices each in their own named btrfs cache pool, and performance over time on these devices plummets down until i'm seeing less than 20MB/s write speeds when copying files. If i manually force a trim, i then see (as an example) 85GB trimmed, and the drive then speeds back up again. The system log is showing the drive as having been trimmed with the dynamix plugin, but it just doesn't look like it's working to me. Perhaps i need to completely remove the dynamix plugin if its not needed? On unRAID 6.9.2 by the way

Actually just checked logs and looks like it is working. Weird how the speeds seem to be lousy at times. The Sabrent nvme drives are excellent too (not like the corsair MP510s!)

Hmm it's using M.2 drives, so the HBA should be irrelevant

Can't seem to find a definitive answer to this, but copying to my cache drives is plummeting down to below 20MB/s at times, and it "feels" like the drive isn't being trimmed Does anyone know?

This is fixed. Changed CPU to a 3900X and it sees all 64GB. Obviously a weaker IMC on the older Ryzen chip

Could be related to the IMC on the Ryzen CPU. Zen+ might not have the juice to run 4 RAM sticks. Ill try a newer CPU

Add this to advanced settings inside "extra parameters" inside every container --log-opt max-size=50m --log-opt max-file=1

There is an option for Above 4G Decoding, but that's only relevant for GPUs? This is the RAM i have, its dual ranked, which should work on all four slots @ 2666 - CT16G4WFD8266 CPU is the 1600 AF which i believe is classed as Pinnacle Ridge

I went through the BIOS options one by one, and nothing seemed to affect it. I increased the voltage from stock and also tried dropping the memory speed. Made no difference. BIOS shows 64GB, but memtest and unraid both only show 32GB.

Hmm, ran memtest and only showing 32GB.... i need to see wtf is going on here OK tried every stick of RAM one at a time, and all good and detected in memtest. However, i can't get more than 2 sticks of RAM to show in memtest, despite all four showing in the BIOS. Memory is set to auto speed (2666) with default settings. Very confused

Hi, I have 4 x 16GB Crucial ECC RAM inside my Asrock Pro4 board, all detected fine inside the BIOS and showing inside the info section of unraid However, the usable RAM seems to only be 32GB, and i can't work out why I am on the latest BIOS and the RAM is supported on the board by Asrock. No onboard video consuming RAM, its got a discrete card The RAM is seated correctly (or wouldn't show in the BIOS) Any ideas?

I'm not sure how wise it is to fill the array now, when you have tons of free space, compared to waiting until you need the space, and then buying the larger drives that will subsequently be out, for the same price. I've done the same thing and kinda wish i hadn't!

As long as the drives are installed back to the same location, the CPU, RAM and board make no difference. Data won't be affected

If you're using a Unifi system, you can just enable MDNS and have Pi-Hole work across all VLANs
