still this is not fixed:
I promoted 4 files from a ec cold tier, and it can be seen that rebal shows as 12 promoted
[root@zod ~]# gluster v tier taylor status
Node Promoted files Demoted files Status

Tested and verified this on the build glusterfs-3.7.5-10.el7rhgs.x86_64 Created 100 new files and verified that they were in the hot tier. Checked the output of 'gluster v tier <volname> status' and 'gluster v rebalance <volname> status'. Promoted 10 files and checked the status. In the next iteration, promoted a single file. After the session time, promoted 2 new files and demoted 1 file. Did a third round of promote/demote. Verified the output of the following commands, at every stage: * gluster v rebalance <volname> status * gluster v tier <volname> status * ls -l <hot-tier path>; ls -l <cold-tier path> No failures were seen in the rebalance output, and the rebalance number was in sync with the promote/demote number shown in tier status, and that in turn was in tune with the files actually heated/cooled. Moving this bug to verified in 3.1.2. Detailed logs are attached. Created attachment 1104253 [details]
