Sounds like a LUKS problem, maybe it can't do those large offsets? xfs
certainly can...
I bet you'll find that the 2GB size is the threshold... xfs is just
trying a write():
if ((bytes = write(fd, z, bytes)) < 0) {
fprintf(stderr, _("%s: %s write failed: %s\n"),
progname, __FUNCTION__, strerror(errno));
maybe try a simple dd write at the end of your large luks device, see
how that goes.
