FredG89 Posted January 11, 2015 Share Posted January 11, 2015 For about a week know. I've been having super slow speeds when writing to UnRaid. I have a cache drive setup and I can see the files on the drive after it's written but I'm averaging between 14-20/MBs. Anyone have any possible idea why this may be? I'm running UnRaid 5.0.5 on An AMD A8 6600k processor. Link to comment
FredG89 Posted January 11, 2015 Author Share Posted January 11, 2015 Whats the website that we use to post logs? It's basically so the log doesn't take up too much space. Link to comment

trurl Posted January 11, 2015 Share Posted January 11, 2015 You can just attach the zipped syslog to your post next time. You have a lot of plugins. Try booting in SAFE mode and see if the speed improves. Link to comment
FredG89 Posted January 11, 2015 Author Share Posted January 11, 2015 I've had these plugins for at least 4 months. You think the plugins are slowing down the drives ability to read/write? I'll try what you suggested and let you know what happens. Link to comment
FredG89 Posted January 11, 2015 Author Share Posted January 11, 2015 It's still transferring at about 20MBs. Should I just install a fresh copy of Unraid? Split level wouldn't have anything to do with it since it's copying to the cache first right? Just in case my settings are 'most free' and with split level 2. Link to comment
trurl Posted January 11, 2015 Share Posted January 11, 2015 20MB/s is a little slow but not unreasonable if it is writing to a parity-protected array. Are you sure it is writing to cache? Try writing directly to the cache drive. Link to comment
FredG89 Posted January 11, 2015 Author Share Posted January 11, 2015 No, I don't even have a parity drive right now. Will try and write directly to the cache. Link to comment
FredG89 Posted January 11, 2015 Author Share Posted January 11, 2015 Nope, still writing at 20-22 MB/s. Link to comment
trurl Posted January 11, 2015 Share Posted January 11, 2015 Unless your cache is an SSD or something there is no advantage to writing to cache if you don't have parity. What exactly do you mean by writing? Are you copying files over the network? Maybe you have a network issue. Link to comment

What exactly do you mean by writing? Are you copying files over the network? Maybe you have a network issue. I have the cache mainly for the applications. The way the apps are set up, they download the files to the cache and then mover transfers the files over. When I say "writing" I mean copying files over. I don't think it's a network issue because when I'm transfer files from UnRaid to my computer, there are no slow downs. Even when I copy from the cache to the drives. It writes super slow. Could it possibly be with Unraid? I'm looking at my screen connected to unraid and it keeps saying "could not open input file plugins/webgui/etc.......... Link to comment
Squid Posted January 11, 2015 Share Posted January 11, 2015 Are you sure that your cache drive is set? I could be wrong, but I see in your device inventory that you've got 8 hard drives, but only 7 of them are being imported. Your 1TB WD (sdb) isn't being imported which I'm assuming is your cache drive. In my syslog, I get this line when it's importing the cache drive: emhttp: import 24 cache device: sdk Like I said I could be wrong, especially since I'm not running 5.x anymore and maybe the lines don't show up in its syslog EDIT: Nevermind... I just noticed it importing. Looks like the logging differs from 5.x to 6 Link to comment

By imported, do you mean being mounted? If so I would think so because all my applications work correctly and I can physically go to the drive. Link to comment
FredG89 Posted January 11, 2015 Author Share Posted January 11, 2015 It also says there was a problem with share libraries or something like that and that sda1 was not unmounted properly. Link to comment
Squid Posted January 11, 2015 Share Posted January 11, 2015 Yeah well I was wrong about it not importing, but what I find really strange is why it's showing that it keeps reimporting the disks over and over and over again starting at 1:39:40 until you stopped the array (~50times). Seems to me it should only do it once until you stop the array. Did you try rebooting and selecting SAFE mode? Link to comment
FredG89 Posted January 11, 2015 Author Share Posted January 11, 2015 Changed ports on my switch. Changed the cable connecting to the cache drive and still the same. Link to comment

Think installing a fresh copy would help? I've been wanting a reason to install a fresh copy. lol Link to comment

I've been wanting a reason to install a fresh copy. lol Something's not right, but I would would more inclined to think a plugin is somehow interferring, and for whatever reason its still being executed with safe mode on. After you redo your flash drive, I would test your transfer speeds before installing any plug ins, and then only install one plugin at a time and test after each one. Link to comment

Now it's back up to normal. Going to install the plugins now and see if that affects them. Link to comment
FredG89 Posted January 11, 2015 Author Share Posted January 11, 2015 Welp. It worked for the first file, but now it's back down to 30MB/s. I've tried without the cache mounted. I've tried without plugins. I've tried different allocation methods. I've tried with different disk file methods. I don't know. Link to comment
Squid Posted January 11, 2015 Share Posted January 11, 2015 Post another syslog after you've copied a file slow... Ideally one that doesn't have any plugins running Link to comment
FredG89 Posted January 11, 2015 Author Share Posted January 11, 2015 Post another syslog after you've copied a file slow... Ideally one that doesn't have any plugins running Ok, I don't know what just happened...but the speed is back to normal. Only thing I did this time was to use putty to telnet to the server and while I was view the log file, I copied some files. W......T......F? Link to comment
Bungy Posted January 11, 2015 Share Posted January 11, 2015 Have you run a SMART test on your cache drive? I wonder if the cache disk is failing. Also, are you running these speed tests while the mover is also running? Link to comment

Also, are you running these speed tests while the mover is also running? The cache drive is fine. I also tried writing to the files without the cache drive being mounted and it gave the same results. I played around with disk allocation methods and split levels and they all gave the same results. Link to comment
