Microsoft REFS Network Drive

I Am a little lost in why my Mac is having issues with the file size and a specific network drive using REFS. This new drive format is supposed to be a step up from NTFS file systems with redunancy built in and handle longer file names along with larger file sizes. However, when I tried to send a 6gb file over my network to the drive formatted with REFS, it simply didn't work. Stating that the file was to large for the drive. Does anyone know a fix to this issue, or should I just reformat the network drive as NTFS.

Thanks!

MacBook Pro with Retina display, OS X Yosemite (10.10.2)

You appear to have forced your Mac to use SMB1 which your output shows should have support for large files. You should try SMB2 or SMB3 as well and see if they have any better success.

Apple will not be interested in fixing this for El Capitan and certainly not Yosemite as both are discontinued so you need to test this with Sierra and if it still does not work report this as a bug to Apple.

You could either try SMBup as a way of replacing Apple's SMB client, or you could try Acronis Access formerly known as ExtremeZ-IP which adds AFP network file sharing to a Windows server. See - http://www.acronis.com/en-gb/mobility/access-advanced/

I should point out you have been drip feeding out additional facts that were not in your original post. You did not originally state that you had successfully used NTFS on the (presumed) same server. Only your very latest message added this.

Neither SMB2 or 3 make ANY difference. Usually make things worse

I am not intending to use Sierra on this hardware (Yosemite does all I need perfectly fine, thank you)

But I will test it on different hardware. Last time I tried SMBup, it messed everything up, so had to revert to default setup.

As to "drip feeding", these forums are so bad that there is not even Edit option!

I am not getting ExtremeZ-IP to install on Windows server, there really is no need. I just do not use ReFS, way simpler

So while I appreciate all your replies here John, they did NOT bring anything new to this thread, sorry
