Description

It's very dangerous to run sanity tests on real Lustre share because it removes all files from Lustre share. Instead of removing all files we need to gracefully cleanup used files after each test.

The code in test_72a:

# We had better clear the $DIR to get enough space for dd
rm -rf $DIR/*
