[ovirt-users] 4.1: warning low space and critical space action blocker not honoured?

[Gianluca Cecchi]

Hello,
I have a small export domain while doing a test.
So I would like to temporarily lower down warning and critical to the
minimum, so that I complete the test and then I re-enable default ones:
Initial situation with "engine-config -g"

CriticalSpaceActionBlocker: 5 version: general
WarningLowSpaceIndicator: 10 version: general

This is confirmed by what I see in RACTOREXP export storage domain general
pane:

Size: 49 GB
Available: 38 GB
Used: 11 GB

Warning Low Space Indicator: 10% (4 GB)
Critical Space Action Blocker: 5 GB

I set both to 1
[root at ovmgr1 ~]# engine-config -s WarningLowSpaceIndicator=5
[root at ovmgr1 ~]# engine-config -s CriticalSpaceActionBlocker=1

Systemctl restart ovirt-engine

[root at ovmgr1 ~]# engine-config -a|grep "Space[A,I]"
CriticalSpaceActionBlocker: 1 version: general
WarningLowSpaceIndicator: 1 version: general
[root at ovmgr1 ~]#

But the storage domain still shows the previous values in webadmin gui.
I tried also to put in maintenance the storage domain and then activate it
again but no change.
And if I try to export a VM with 30Gb of disk I get the error and in the
engine log

What I'm doing wrong?
