Hi, different symptom, but the same cause: find -inum (on stretch) doesn't find files that are mounted because it uses d_ino from getdents(), which contains the inode number of the moint point rather than of the directory entry.
The specific use I encountered this bug with was finding a network name space based on its inode number--but since network name spaces are mounted, you can't use find for that anymore. Florian
