Public bug reported:

Glance version = 0.12.0 / 2014.1

In python package /usr/lib/python2.6/site-packages/glance/store/filesystem.py 
 _get_capacity_info(self, mount_point)

To determine the free space of a store, the python script executes df
with option "--block-size=1", in later version (I noticed), this was
changed into "-k" to work with kbytes, but in both situations, when the
mountpoint name is too long, or the size is to big, the output of df
will be multilined, resulting in an IndexError, because only one line is
being searched for values.

Fix:
When adding the option -P (or in long form --portability), the output is Posix formatted, resulting in one line per filesystem output.

Regards,

Maurice Leeflang
