[Very slow transfer speeds in Krusader to populate server]

If you install the Fix Common Problems App does it say anything about Write Caching?

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.

Or stay on 6.6 until the issue is resolved.  But yes easy upgrade to 6.7. 

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

Post Diagnostics taken when transferring. 

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?

[Very slow transfer speeds in Krusader to populate server]

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!
