If you are using ZFS as the underlying filesystem.
ZFS by default stores the extended attributes in a hidden directory instead of extending the file inode size like what XFS do!
There is a problem in ZFS on Linux implementation which the function responsible for deleting the files, it deletes only the files and forgets to delete the hidden directory which stores the extended attributes, and there seem no interest from ZFS on Linux community to fix this bug, it’s filed since 2013.
There is an option to change this to write the extended attributes to the inode instead of a hidden directory.
# zfs set xattr=sa <POOL_NAME>

It only deletes the metadata. when viewed through shell, it still exhibits the file in the directory. only way to delete fully is through glusterfs-client.
