Cpio archives can only store files up to 8589934591 bytes long.

Because the standard cpio archive header (odc) encodes file size using
a field of 11 octal digits:

  077777777777 = 8589934591

Solaris cpio suffers from the same limitation. According to
the sun's largefile(5) manpage:

     The /usr/bin/cpio and /usr/bin/pax utilities are large  file
     aware,  but cannot archive a file whose size exceeds 8 Gbyte
     - 1 byte.
