Description Nag Pavan Chilakam 2015-04-02 06:58:05 UTC

Description of problem:
=====================
Attaching a tier to a replica volume is not getting converted to a tier-replica volume.
Instead it is just getting converted to dist-rep volume with no tier gfid issued for each brick


Version-Release number of selected component (if applicable):
===========================================================
upstream nightly

How reproducible:
===============
easily


Steps to Reproduce:
==================
1.create a pure replica volume with two bricks which are replica of each other ie 1x2
2.now attach a tier to it
3.the volume should now get converted to tier-dist-rep volume but is getting converted to just dist-rep vol

Actual results:
==============
the volume should now get converted to tier-dist-rep volume but is getting converted to just dist-rep vol

Expected results:
================
support replica volume to be converted to tier type

Comment 1 Dan Lambright 2015-04-21 18:40:49 UTC

This problem is similar to bug 1207204, it was fixed by 10054- the new volume name is "tier" after the attach occurs. 

The gluster v info will be updated and this is being track separately by bug 1206546.

Comment 2 Niels de Vos 2015-05-15 13:07:38 UTC

This change should not be in "ON_QA", the patch posted for this bug is only available in the master branch and not in a release yet. Moving back to MODIFIED until there is an beta release for the next GlusterFS version.

Comment 3 Joseph Elwin Fernandes 2016-02-14 04:15:21 UTC

This bug is fixed in https://bugzilla.redhat.com/show_bug.cgi?id=1207204
