Is there any way to increase the file size limit on UBIFS beyond 2Gbytes? I have tried enabling the kernel ‘Support for large block devices and files’ under ‘Enable the block layer’, but the 2G limit persists.

Regards,

Dave.

We never tested this, but should not be. AFAIR, UBIFS theoretical limitation should be something like 16TB, but I tried tested the maximum file size.

UBIFS has nothing to do with block devices. This is a very specialized FS for bare flashes:

So that option has no effect for UBIFS.
