Description Dan Lambright 2016-08-17 15:38:23 UTC

+++ This bug was initially created as a clone of Bug #1333220 +++

Description of problem:
With a teired volume, a df -h shows a capacity equal to the hot + cold tiers. This is wrong, since the hot tier is a cache layer not an extension of the volumes capacity.

Version-Release number of selected component (if applicable):
tested against 3.7.10

How reproducible:


Steps to Reproduce:
1. create a tiered volume
2. mount it and run df -h 


Actual results:
df -h shows a combined capacity view of hot+cold

Expected results:
df -h should show the capacity of the cold tier, since the cache layer is 'transient'.

The patch has been abandoned as it was not requested and 3.8 is about to reach EOL.
