db_lmdb.hpp:15] Check failed: mdb_status == 0 (-30796 vs. 0) MDB_CORRUPTED: Located page was wrong type

Fresh, successful Caffe installation on Ubuntu 16.04. Caffe was compiled on the system for CPU-only operation. LMDB version 0.9.17-3 is installed as well. Everything is very 'vanilla'.

To double check everything, I followed the MNIST installation instructions:

cd $CAFFE_ROOT
./data/mnist/get_mnist.sh
./examples/mnist/create_mnist.sh

The third script is the one that generated the aforementioned error. Does anyone know the cause?

I found a method to solve this,

1. you can vim the file$CAFFE_ROOT/include/caffe/util/db_lmdb.hpp ,
2. comment out the line CHECK_EQ(mdb_status, MDB_SUCCESS) << mdb_strerror(mdb_status);
3. return to the $CAFFE_ROOT, remake caffe by make -j

By the way, you can run make test && make runtest to test if caffe works.
