[LU-3973] cleanup_large_files may use df incorrectly

Tue, 3 Jun 2014 12:38:18 +0000

The test in sanity-hsm.sh's cleanup_large_files is often failing with the following:

/share/lustre-release/lustre/tests/sanity-hsm.sh: line 393: [: /mnt/lustre: integer expression expected

which is because df is using an unexpected output format:

t2:~# cat /etc/centos-release
CentOS release 6.4 (Final)
t2:~# df --version
df (GNU coreutils) 8.4
