This is not a file permission issue. Somehow after a clean shutdown the WiredTiger.wt file is missing and this means you cannot start mongodb again, effectively losing the database.
I have seen this a few times since using wired tiger, on 3.0.2 and currently on 3.0.4
This is out /etc/fstab for /data partition:
`/dev/xvdb /data xfs noatime 0 0`
Here is the mongodb log:
