Comment 5 Sweta Anandpara 2015-12-22 04:13:46 UTC 
Tested and verified this on the build glusterfs-3.7.5-12.el7rhgs.x86_64

Tried out different combinations of volume name (with tier substring in it) and performed a rebalance, which worked as expected. 

Moving this bug to verified in 3.0.2. Detailed logs are attached!
