I've narrowed down the strange behavior to sort of minimal example (/mnt/archive is a NetApp mount point):

umount /mnt/archive && mount /mnt/archive \
    && stat --printf "%d\t%i\t%n\n" /mnt/archive/.snapshot \
    && stat --printf "%d\t%i\t%n\n" /mnt/archive/.snapshot/hourly.0 \
    && stat --printf "%d\t%i\t%n\n" /mnt/archive/.snapshot

The output is following:

    20 67 /mnt/archive/.snapshot
    26 222 /mnt/archive/.snapshot/hourly.0
    26 67 /mnt/archive/.snapshot

The device number is being changed on the fly while the inode number stays unchanged. It sounds like a file system bug to me. It's 100% reproducible on my box.
