Unraid share2share copy - via network instead of direct

[hot-descendant6904]

I think my issue is related to the samba settings in unraid and the used client OS:

 

- Windows11 (latest version) client: copy from unraid share to unraid share result in almost no network traffic and data transfer rates between the shares only limited by the drives (~250 MB/s) and not the gigabit network

- Kubuntu (latest version) client (on same hardware) with SMB3 set as min max protocol in smb.conf: copy form unraid share to unraid share results in maximum network traffic and data rates between the share are limited by the gigabit network.

 

My unraid smb settings are:

 

Hide "dot" files: no

Enable SMB Multi Channel: yes

Enhanced macOS interoperability: yes

Enable NetBIOS: no

Enable WSD: no

 

No optional settings/configurations.

 

So my goal is to have a setup that copies files between unraid shares with alomost no network traffic even if I use kubuntu. What do I need to do?

Are you  actually making a copy, or do you really mean you are moving files from one share to another?

It could be that Kubuntu does not utilise the Samba facility to do server side copying.

Linux

The Linux Kernel CIFS client includes support for issuing SMB2 FSCTL_SRV_COPYCHUNK_WRITE server-side copy requests. This feature can currently only be utilised by issuing a special CIFS_IOC_COPYCHUNK_FILE ioctl, as done by cloner in the xfstests Git repository.

Very good reply. Now I have also a word for what I am looking for: Server-Side-Copy. 

 

- So do I get it right, that this is something that needs to added/changed in Dolphin e.g.? I wonder why this is not already implemented in the file managing tools?

- Does anybody know a file managing tool that uses "server-side-copy" by default (using the necessary parameter for the cp command)?

Dynamix File Manager plugin will let you do all file management server-side.
