xfs type inode  No space left on device

inode64

  Indicates that XFS is allowed to create inodes at  any  location

  in  the  filesystem,  including those which will result in inode

  numbers occupying more than 32 bits of  significance.   This  is

  provided  for  backwards  compatibility, but causes problems for

  backup applications that cannot handle large inode numbers.
