Mac OS finder shows size of 0 bytes for every file

I don't have access to a Mac and can't get OS X running in a VM, so I would appreciate if anyone could investigate this.

Yes, I can reproduce:

The problem is that files in Fuse don't seem to register in OS X's metadata store, a problem one can confirm by simply running mdls. For instance,

> file=/Users/zmwang/sync/acd/vid/event/apple/20111004-apple-special-event.mov
> mdls $file
/Users/zmwang/sync/acd/vid/event/apple/20111004-apple-special-event.mov: could not find /Users/zmwang/sync/acd/vid/event/apple/20111004-apple-special-event.mov.
> ls -sh $file
4.6G /Users/zmwang/sync/acd/vid/event/apple/20111004-apple-special-event.mov

I'm not sure why. Maybe it's OSXFUSE's fault.

By the way, trying to QuickLook a directory returns the size just fine.

Digging into mds a bit further, it seems that metadata server has trouble with the whole volume:

> mdutil -s ~/sync/acd
/Users/zmwang/sync/acd:
    Error: unknown indexing state.

From system logs:

1/20/16 12:38:41.888 AM mds[67]: (LSOF.Error:244) File '/Users/zmwang/sync/acd' (fd=33) left open on device 788529162

...

whatever those means.

@yadayada I don't have this problem in the macOS (10.11.6) and it's showing all the file sizes so I think that's fixed because it wasn't like this before.

It is due to OSXFUSE: mounting a volume with the auto_xattr option solves the issue, at least in my case (See https://github.com/osxfuse/osxfuse/wiki/Mount-options#auto_xattr). DISCLAIMER: I am not an acd_cli user.
