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
-
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!
-
If you're using a Unifi system, you can just enable MDNS and have Pi-Hole work across all VLANs
-
Many thanks for your extensive investigation here. Having just spent over £500 on two 2TB nVME drives, i appreciate it!
-
Old thread but yes this is indeed a problem. My 2 year old Samsung 850 Pro SSD (which was used for cache for only 12 months!) has over 450TB written which effectively means the warranty is now void...
-
Messaged LT, lets hope they can help get this fixed!
-
Exact same issue happening to me. Server locks up completely when copying to BTRFS cache drive (single drive) Seeing IOWAIT up to 50% plus Samsung 850 Pro 2TB SSD using motherboard SATA Raised in bug section as a problem. Frankly surprised this doesn't appear to be getting looked into by LT, given how Samsung make arguably the most popular SSDs in the world?
-
@spamalam That's actually a great idea.
-
I would go through every docker container and remove access to mnt/user if i was you though, unless the docker needs access to every single share on your server? It's a bit of a pain, but worth the effort imo
-
Did you sort out the rogue access to your server? That would worry me!! Your unRAID server should NOT be public internet facing, only via your internal LAN If you have external ports forwarded to it, i would sort that out ASAP. Connect to it using something like OpenVPN instead.
-
If copying a large file to a server share (Windows 10 1909 SMB protocol) which is using cache, the entire CPU will be maxed out on every thread, and the server locks up. DNS will then fail as the Pi-Hole docker will bomb out (all other dockers will fail too), and it only returns if you let the copy complete, or you cancel the file transfer. Disabling cache prevents this issue I have read other people have seeing the same issue here. Screenshot of glances running and unraid CPU usage whilst movie is copying over the network (gigabit lan) Marked as urgent, as dockers all crashing out means Plex stops working (angry wife and kids...!) and internet stops working across the entire network as PiHole fails (no DNS). Could disable cache, but then why have it? Samsung 850 Pro 2TB SSD for cache, with appdata, one running Windows Server 2016 VM and the docker image. EDIT - Just updating after finding more information out regarding this issue. So this seems to be due to using a Samsung SSD with a BTRFS file system. If you switch the file system to XFS it resolves the problem. Obviously if you're wanting to use a cache pool with Samsung SSDs you're currently SOL until this is fixed goku-diagnostics-20200225-1917.zip

No worries dude. The community here is pretty helpful, i use them myself, no thanks necessary

Found these bit of info online too:- "If you're using a cheapo third party USB-C cable, it might only support USB 2.0 High Speed transfer rates (if it doesn't have wires for all the USB 3.1 pins)." "Type C defines a connector. It doesn't define speed. This is like assuming all M.2 slots are faster than SATA. M.2 can also use SATA based drives in addition to NVMe." i would say mystery solved...!
-
Also, i wonder why the drives are showing as JMicron generic instead of the actual drive serials. This suggests to me that perhaps they are not connected bare metal? I still think its a issue with USB2 though as said above, especially as the speeds seem about right for USB2. Probably stating the obvious here, but make sure you're connected to one of the blue USB ports
