Description krishnaram Karthick 2016-05-17 13:41:05 UTC 
Description of problem:
When detach tier commit is attempted before the tier-rebalance is complete, it fails with the following error message.


# gluster v tier spiderman detach commit
Removing tier can result in data loss. Do you want to Continue? (y/n) y
volume detach-tier commit: failed: Brick's in Hot tier is not decommissioned yet. Use gluster volume detach-tier <VOLNAME> <start | commit | force> command instead
Tier command failed

The following portion of the error message isn't clear.

Use gluster volume detach-tier <VOLNAME> <start | commit | force> command instead

We should ask the user either to wait till tier-rebalance is complete or use force option to forcefully detach the tier

Version-Release number of selected component (if applicable):
glusterfs-3.7.9-5.el7rhgs.x86_64

How reproducible:
Always

Steps to Reproduce:
1. On a tiered volume, run detach tier commit before running detach tier start
Comment 2 Dan Lambright 2016-05-19 14:39:40 UTC 
will change the message to 

volume detach tier commit: failed: Bricks in hot tier are not decommissioned yet. Use gluster volume tier <VOLNAME> detach start

As tier is not being actively developed, I'm closing this bug. Feel free to open it if necessary.
