LM Studio Unsupported Format Error caused by non-ext4 filesystem

I get an Unsupported Format error for literally every model I download for LM Studio. Also, the time stamp of the file is…

After digging around a bit, I realised that the error is related to my filesystem type (f2fs /home). Moving the models cache directory to an ext4 “fixes” the error.

I was hoping someone could shed some light on why this might be happening.

Note: the error does not interfere with the model’s function.

I suggest you create an issue with the developers - describing in detail your issue.

There are many file systems that can be used in Linux. But that doesn’t mean you should use them productively :wink:

I would suggest ext3/4 or btrfs or any “non-fancy” file system from Linux’s past.
(Not NTFS, not FAT) such as reiserfs…

The fancy file systems like ZFS… are also good, but require some expertise and maintenance.
:footprints:

I don’t understand why they would even check the file system. It should be transparent to the user space and the kernel should care about it.

I will do that, I just wanted to be sure I’m not missing something in my OS configuration.

That is understandable - f2fs is a great filesystem - some file systems may be better suited for certan tasks.

There is only Linux file system

It is good for a bootable USB stick - but it has some quirks - which in my personal experience was undesirable for my workstation.

I test btrfs and xfs on encrypted laptops - the jury is still out on those :slight_smile:
