 Description   

It turned out the objects are object accounting objects and somehow they are created under MASTER_NODE_OBJ. We should create them under root directory of dataset.

This specific object will become obsolete as soon as the ZFS dnode accounting feature is available for use.

However, I think that there may be other ZFS OSD objects that similarly do not have a proper pathname (only a FID), but I don't have any specific example right now.

Yes, all dynamically created object with seq number ```FID_SEQ_LOCAL_NAME``` don't have names.

I think (most of) the nameless objects in osd-zfs are being fixed as part of ZFS OI Scrub patch https://review.whamcloud.com/28610

Is this work still needed?
