Description Kevin Alon Goldblatt 2015-01-22 13:55:27 UTC 
Description of problem:
Bad error when adding vm to pool with low space on storage domain when within the threshold limit

Version-Release number of selected component (if applicable):
rhevm-3.5.0-0.30.el6ev.noarch
vdsm-4.16.8.1-6.el6ev.x86_64

How reproducible:
Every time

Steps to Reproduce:
The following scenario's were tested:

Adding vms to N existing pool:  

Available space:     Space required:     Pool based on Template:     Result:
------------------------------------------------------------------------------------------------------------------
5g                   2g                  VM with BLOCK disks        Passed
5g                   10g                 VM with BLOCK disks        Failed with Low space on Disk

5g                   20mb                VM with FILE disks         Passed


4g                   2g                  VM with BLOCK disks   Failed with 
"Cannot edit VM-Pool. One or more provided storage domains are in maintenance/non-operational status."

4g                   20mb                VM with FILE disks    Failed with 
"Cannot edit VM-Pool. One or more provided storage domains are in maintenance/non-operational status."



So what we have here is when the available space on the storage domain in wWITHIN THE THRESHOLD limit, the error displayed when trying to add more vms to the pool:




Actual results:
currently reads: "Cannot edit VM-Pool. One or more provided storage domains are in maintenance/non-operational status."


Expected results:
SHOULD read: "Cannot add vms to pool, Low disk space on storage device!"

This bug blocks the verification of bug 1179690, which is targeted to 3.5.1. Tentatively suggesting it for 3.5.1 too, pending PM and QA acks to confirm and clone (or refute and retarget bug 1179690 too).
