There is this comment in /usr/include/ufs/ffs/fs.h:
/* Maximum file size the kernel allows.
* Even though ffs can handle files up to 16TB, we do limit the max file
* to 2^31 pages to prevent overflow of a 32-bit unsigned int. The buffer
* cache has its own checks but a little added paranoia never hurts.
*/
#define FS_KERNMAXFILESIZE(pgsiz, fs) ((u_int64_t)0x80000000 * \
MIN((pgsiz), (fs)->fs_bsize) - 1)
Now page sizes differ within OpenBSD, so then it depends between 8 TB (4096
bytes page size) and higher perhaps?
