When listing folders the following errors are seen and several folders cannot be browsed. This is using latest apfs-fuse on Ubuntu 14.04 32-bit. See below trying to run ls -al on root of mounted disk.

same problem on raspbian 9
Disk was created on MacOS Mojave 10.14.2 and is fully encrypted

[ydkhatri]

Mine was not encrypted.

Strange ... never encountered this problem before.
Can you run it with -d 255, execute the ls -al and post the console output?

[ydkhatri]

Can you run it with -d 255, execute the ls -al and post the console output?

Output was a little large, so attaching as files here:

debug_on_mount.txt
debug_ls-al_root.txt

[sgan81]

Thanks, I will look into that.

Ok, I see the problem ... all files with inode numbers > 4G fail. Because fuse_ino_t is defined as unsigned long, which is 32 bits on 32-bit platforms, and APFS uses 64-bit object id's. This will be quite hard to get working on 32-bit platforms ...

[ydkhatri]

Thanks that makes sense. Perhaps you could also add a note to use only 64bit platform. Maybe even a check in code, so it can't be compiled on 32bit.

[sgan81]

Actually, the inode size has been defined as 64 bit in upstream since 2013, which would solve the problem ...
With a newer version of fuse than what you and I were using, this should actually be quite simple to fix. But I need to investigate a bit more.

[sgan81]

I have now updated apfs-fuse to use FUSE 3.0, it does now run properly on 32-bit systems.

You probably need to manually build and install fuse 3 on Ubuntu 14.04. The latest fuse version not requiring meson to build is fuse 3.1.1, which worked fine in my tests.

[ydkhatri]

Thanks, will take a look.
