I've been running into an issue where as I'm moving files from my linux desktop to an unraid share the cpu usage on the unraid server increases. If I'm moving enough files I will end up with 6-8 cores (of 24)  pegged at 100% usage and the file transfers will start to fail on the desktop side diving me an error that the location is unavailable.

 

I'm on unRAID 6.8, but had this issue on the 6.7+ versions. I'm using a 500GB SSD cache pool and have plenty of space left open (300GB+). I have 48GB of ram and the server is using no more than 50% of the ram when these errors occur.

 

Any help would be greatly appreciated.

 

Thanks

I posted a thread and have the same issue.

Good to know it‘s not only me.

Are you also using Linux or Windows?

Windows, but it also happens when I tested it from MacOS.

And it's not my network, when I tested it with a share from my Windows PC to the MacOS machine it was working flawless.

It only happens with shares from Unraid.

Same with me. I've also tried Windows and MacOS.

 

I've tried to eliminate as many things as I can. With and without my one VM running, I've removed a pci-e USB 3 card and AMD GPU. I have a bonded dual 8023ad (supported in my ubiquiti switch) that I have tried with and without. None of these things make a difference for me.

An update. I'm using kde as the a desktop on Linux. The file manager, Dolphin, allows me to use sftp for setting up network shares. When I do that all my issues go away. The transfer speed is much better and I don't get any time outs or any of the cpu issues.

 

There seems to be a lot of issues with Samba in unRAID right now.

 

 

Yes, i saw that aswell.

But maybe i found a solution, i don't know yet .

I moved some files around and made sure that there is at least 50GB free space on my drives.

Since then my tests are performing better than before and i see constant write speeds of 75 MB/s over SMB with single parity.

And also no time outs.

 

What is the fill level on your drives?

My drives are all over the place , but the lowest is 180G free. I am writing to a cache pool though, that is 2 500GB drives and they are at 300GB free. So in my case there is plenty of space.

 

I moved a bunch of files around yesterday and using sftp instead of samba is definitely my temporary fix. No issues at all.
