--- Comment #4 from nchilaka <nchilaka at redhat.com> ---
I have verified this on the latest build:
1)check default ctr on a regular volume which was off as expected
2)attached tier to a regular volume and ctr was enabled by default on volume
3)attached a tier to an offline regular volume and ctr was enabled even on
offline volume

hence moving to verified.
