LTFS13514E Failed to write extended attribute "STRING1" to on-disk dentry cache "STRING2" (VALUE1)

Explanation
      
    The extended attribute STRING1 cannot be written to the dentry cache STRING2 on disk.  This error occurs when there is no disk space left for dcache or if too many extended atrributes are specified to a single file or directory.
  

  
Operator response
      
    If there is no disk space left for dcache, LTFS automatically increases the dcache space up to the maximum size. Once the maximum size is reached, LTFS switches to read-only mode.  In this case, you must expand the dcache space by using 'expand_dcache.sh'.
If the cause is too many extended attributes, the operation that returned this message is not possible with dcache enabled.
