whereis <file-path>¶
Retrieve an assigned object by the file-path Paths used by whereis are ruled by this rule
$ leofs-adm whereis leo/fast/storage.key

If you want to retrieve an object whose file-path contains spaces, Enclose the file-path with double quotation.
$ leofs-adm whereis "leo/fast/storage with space.key"
