--- Comment #2 from Amar Tumballi <atumball at redhat.com> ---
Patch https://review.gluster.org/#/c/glusterfs/+/21331/ removes tier
functionality from GlusterFS. 

https://bugzilla.redhat.com/show_bug.cgi?id=1642807 is used as the tracking bug
for this. Recommendation is to convert your tier volume to regular volume
(either replicate, ec, or plain distribute) with "tier detach" command before
upgrade, and use backend features like dm-cache etc to utilize the caching from
backend to provide better performance and functionality.
