Description

Contrary to best practice, units are not provided in the output of
/usr/bin/obdfilter-survey

for example:

Fri Sep 25 11:14:03 EDT 2015 Obdfilter-survey for case=disk from hds1fnb6123

Sadly, the output is also not documented in the Operations Manual:

Units are provided in the helpful README:

./lustre-iokit/obdfilter-survey/README.obdfilter-survey

there is, however, an error:

sz 67108864K   is the total amount of data read or written (in KB).

This should read 'read or written (in bytes)'

and the same for rsz, which now has a 'K' after it...
