Add the ability to remove LUN(s) from an existing storage domain
Comment 1 Liron Aravot 2016-12-28 07:27:53 UTC 
Allon/Tal, this feature was completely merged but its currently disabled until the issue described in 1403836 will be solved.
How do we want to mark it in bugzilla?
Comment 2 Liron Aravot 2016-12-29 09:54:31 UTC 
After talk with ydary, marking as BLOCKED till the lvmetad issue this bug depends on will be solved either by us (disabling lvmetad) or in lvm.
Comment 3 Tal Nisan 2017-01-12 13:23:40 UTC 
Liron, please fill out a doc text.
As for the other question, I've asked the QE guys to verify this feature with manually disabling lvmetad so they are not blocked on this bug for now
Comment 4 Lilach Zitnitski 2017-03-09 09:00:43 UTC 
--------------------------------------
Tested with the following code:
----------------------------------------
rhevm-4.1.1.3-0.1.el7.noarch
vdsm-4.19.7-1.el7ev.x86_64

Tested with the following scenario:

Steps to Reproduce:
1. move the storage domain to maintenance 
2. using REST API reduce the lun using it's lun id
3. activate the storage domain

Actual results:
storage domain is reduced and the total space is updated

Expected results:

Moving to VERIFIED!
