Title: Distributed filesystems are awesome

I think Lustre might be failing in a way where /bin/cp exits with non-zero status, but a /bin/ls gives the correct file size. (The file actually fails halfway through a copy and is truncated, but the local node doesn't know that yet).

By replacing ; with &&, a non-zero exit status will propagate.
