The attached test program reliably fails on an NFSv4 mount.
# mount -tnfs -onfsvers=4 127.0.0.1:/ /mnt/nfs # ./truncate-test /mnt/nfs/tmp/xyz truncate: Input/output error
Thanks, Miklos

int main(int argc, char *argv[]) { int res; char *name = argv[1];
unlink(name); close(open(name, O_WRONLY | O_CREAT, 0644)); close(open(name, O_RDONLY));
res = truncate(name, 1); if (res == -1) { perror("truncate"); return 1; } return 0; }
