CommandFailedError: Command failed on target158069070171 with status 2: "sudo TESTDIR=/home/ubuntu/cephtest bash -c 'rbd import --image-format 2 $TESTDIR/foo base-pool/bar'" 

I cannot fathom how this sequence of commands:

dd if=/dev/urandom of=$TESTDIR/foo bs=1M count=1
rbd import --image-format 2 $TESTDIR/foo base-pool/bar

could fail with:

rbd: import failed: (2) No such file or directory
