Removing character mapping

Learn how to remove the ceph.dir.charmap attribute from a directory in CephFS. If the attribute is not set, the directory has no character mapping. Character mapping is inherited only at the time of directory creation. Removing the mapping from a directory does not affect its parent or child directories.

Before you begin

Before you begin, make sure that you have the following prerequisites in place:

Directory must not be part of a snapshot. .
Directory must be empty before character mapping can be removed.
You must have appropriate authorization to modify extended attributes on the directory.

Procedure

To remove the ceph.dir.charmap attribute and restore the default behavior, run the setfattr command.

  setfattr -x ceph.dir.charmap foo/

For example,

setfattr -x ceph.dir.charmap foo/ 
getfattr -n ceph.dir.charmap foo/ 
foo/: ceph.dir.charmap: No such attribute

To confirm that the character mapping was removed, run the following command.
```
getfattr -n ceph.dir.charmap <directory>/
```
For example,
```
foo/: ceph.dir.charmap: No such attribute
```
