Comment 1 Anitha Udgiri 2019-03-07 23:47:24 UTC

Request that due diligence is done to these messages and suppressed as this causes a lot of misunderstanding .

Comment 2 Anitha Udgiri 2019-03-07 23:59:12 UTC

I have attached the vdsm.log and engine.log file from the Customer's env. Let me now if you need anything else.

Comment 5 Pavel Bar 2019-08-07 10:46:36 UTC

The committed patch https://gerrit.ovirt.org/#/c/102315/ fixes the "ReduceImage" warning.
The "RemoveDisk" warning was already fixed in https://bugzilla.redhat.com/1704819 by Shani.

Tried to Verified on ovirt-engine-4.4.0-0.13.master.el7.noarch but encounted bug 1785939 which blocks this effort as snapshot deleted fails and this is the main flow of this bug.

Marking as depends on bug 1785939.

Verified on ovirt-engine-4.4.0-0.17.master.el7.noarch.
Warns not shown at all in both logs (engine & vdsm) and everything work as expected.
