The above patch has implemented only till spawning separate tier process. so a new bug has been created for it
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.
