Need a file system for a Raspberry Pi SMB Server

Hello! 
 

I’ve got a Raspberry Pi 4 which is configured as an SMB file server. It hosts my Plex Media library and personal documents I don’t want in the cloud. Its used by Windows, macOS, and iOS devices. It’s been working good so far however today I attempted to put a 22GB file and ran into the file size limit for exFAT (16GB). 
 

So with that in mind I know there are multiple other Linux file systems. Is there any file system that will give me read/write compatibility with macOS, iOS, and Windows 10 with a larger file size limit?

I assume you mean SMB (Samba). Use xfs or ext4. Your file system behind samba shouldn't really matter, Samba will handle the communication and in turn compatibility.

exFAT does not have a file size limit of 16GB, so are you sure that's the issue?

Well Windows kept complaining that the file size was too big for the destination file system. Doing some further digging it looks like that is in fact not a limitation of exFAT. Windows has never liked my SMB server, macOS has never complained.

That's strange. Do you have any custom user based quotas configured? Windows should work perfectly fine with SMB provided the permissions are correct.

No, I don't have anything special configured at all. It's just a guest writable local network share. It mostly has issues writing, I can read/copy from the pi without issues usually.

16gb sounds like it might be the size of your sd card... or possibly its remaining free space. I have noticed that if you share the folder your drive is mounted on, windows will show available free space on your root partition rather than the external drive. I'm not sure if this is an issue with Windows' samba handling or just the way the protocol works... either way you might want to try sharing individual folders rather than the whole mount point.

Don't ask to ask, just ask... please 🤨

I do have Samba configured to share only the root of the 2TB hard drive I’m using as my drive.

that's what I mean, the mount point is technically part of your root file system on your main drive. depending on how you check for available space you might get different results.

It really shouldn’t be. The SD card is where my OS is installed. If the Pi considers its OS drive in the storage calculations for any mounted drives, that’s bad.

If you connecting over SMB the filesustem won't matter.

I myself use btrfs, but if your not willing to learn how it works then ext4 is fine for the most part on a Pi
