The FS was created 1.5 years ago can explain the issue.
here is way to fix other potential bad files in the FS.
1. List all object whose name end with .00000000 in pool 7
2. Find all non-directory inodes in the FS
3. For all non-directory inodes without corresponding object in pool
7, create an empty object in pool 7 and copy xattr 'parent' from
corresponding object in pool 12 or pool 20.
