Glusterfs GFID Resolver Turns a GFID into a real path in the brick
#!/bin/bash
if [[ "$#" < "2" || "$#" > "3" ]]; then
cat <<END
Glusterfs GFID resolver -- turns a GFID into a real file path
Usage: $0 <brick-path> <gfid> [-q]
<brick-path> : the path to your glusterfs brick (required)
<gfid> : the gfid you wish to resolve to a real path (required)
-q : quieter output (optional)
with this option only the actual resolved path is printed.
without this option $0 will print the GFID,
whether it identifies a file or directory, and the resolved
path to the real file or directory.
Theory:
The .glusterfs directory in the brick root has files named by GFIDs
If the GFID identifies a directory, then this file is a symlink to the
actual directory. If the GFID identifies a file then this file is a
hard link to the actual file.
