Badar Posted August 30, 2019 Share Posted August 30, 2019 (edited) I finally built my first server after hearing about unraid for the past 8 years; I love the features presented so simply to use. However, I'm having a lot of trouble on the initial fill up of data. I installed a krusader docker and tried copying files from a USB 3 HDD mounted to unassigned devices. The copy speeds hover around 20MB/s which is painfully slow for the 20TB transfer i have to do. I did disable parity and cache for the initial transfer due to the huge amount of data. I even tried with NCQ enabled but it makes no difference. What bugs me is that if I plug the same USB to my PC and drop the folder to UnRaid, It saturates the gigabit line and transfers at 125MB/s. I don't want to run two PC's to transfer from a HDD that can be mounted to the server directly. The USB is formatted as NTFS if that helps. Am I missing something? I'd really appreciate any help or advice regarding this. Also, I'm running UnRaid 6.7.2 stable Thanks a lot in advance! Edited August 30, 2019 by Badar Quote Link to comment

I've attached the diagnostics file just taken after initiating transfer again. Copy speeds were 21.9 MB/s. @dalben I can definitely reinstall older version onto USB and try again. Then upgrade to latest version after data is on it? tower-diagnostics-20190830-2352.zip Quote Link to comment
dalben Posted August 31, 2019 Share Posted August 31, 2019 Or stay on 6.6 until the issue is resolved. But yes easy upgrade to 6.7. 1 Quote Link to comment

Tried with UnRaid 6.6.7, unfortunately speeds in krusader still around 24MB/s, I may eventually have to network dump the data onto it. Really hoping someone has a solution based on the zipped diagnostics I uploaded. It's probably something simple Quote Link to comment
Squid Posted September 1, 2019 Share Posted September 1, 2019 If you install the Fix Common Problems App does it say anything about Write Caching? 1 Quote Link to comment

I checked that App and it doesn't say anything about write caching. So I googled and tried the linux command to check the drive and it says write caching enabled, That should be good right? . I'll attach the results to reconfirm that. Thanks for the advice to check this too. root@Tower:~# sudo hdparm -i /dev/sdc /dev/sdc: Model=WDC WD100EZAZ-11TDBA0, FwRev=83.H0A83, SerialNo=JEJS4B5N Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs } RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=56 BuffType=DualPortCache, BuffSize=unknown, MaxMultSect=16, MultSect=off CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=19532873728 IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120} PIO modes: pio0 pio1 pio2 pio3 pio4 DMA modes: mdma0 mdma1 mdma2 UDMA modes: udma0 udma1 udma2 udma3 udma4 udma5 *udma6 AdvancedPM=yes: disabled (255) WriteCache=enabled Drive conforms to: unknown: ATA/ATAPI-2,3,4,5,6,7 * signifies the current active mode Edited September 1, 2019 by Badar Quote Link to comment
darkwalker Posted June 29, 2020 Share Posted June 29, 2020 I got the same issue and can not fix it yet. However, I tried to transfer data via samba in win10 which is a VM built on unraid and then got full speed about 100~200MB/s . Quote Link to comment
