Yesterday I created a small utility to scan the brick and find issues 
with directories created by Gluster. Tool can detect following issues

- No GFID: If a directory in brick backend doesn't have `trusted.gfid` xattr
- No Parent GFID: Parent directory doesn't have a `trusted.gfid` xattr
- No Symlink: Gluster maintains a symlink in `$BRICK/.glusterfs` 
directory for each directory, If Symlink file not present for a directory
- Wrong Symlink: If symlink exists but linked to different 
directory(Same GFID assigned to two directories)
- Invalid GFID: Invalid data in `trusted.gfid` xattr
- Invalid Parent GFID: Invalid data in `trusted.gfid` xattr of parent dir

Installation instructions are available in the repo

     gluster-dir-health-check <brick_path>


     gluster-dir-health-check /exports/bricks/brick1 > 

Grep for "NOT OK" for issues recorded in the above output file.

     grep "NOT OK" ~/brick1_dir_status.txt

More details about this tool is available 

This is a super-young project, please let me know if you face any issues 
while using this utility.

Note: This tool is created using Rust(https://rust-lang.org)
