Moving large files from one share to another locally without using the network...

[Miklos]

Dear Community,

Is there a way moving large files (several GBs) internally from one share to another without using the network?

Even with Midnight Commander in an SSH session the the files are sent to the network interface and then back from the switch...

Any help would be appreciated. 🙂

Thanks,

Miklos

One thing to keep in mind is that each share it it's own BTRFS subvolume. One consequence is that when you move a file to a different share, the system will actually do a copy+delete.  That might be the real cause of the speed issues you are seeing.

If you are using shell commands, you can copy with --reflink and then delete the original.  the --reflink uses CoW's ability to share the datablocks, so it has the same speed as a move.

I don't know if there is any way to configure midnight commander to do that.
