engine & vdsm logs

Description of problem:
Every time (each HE setup with blocked HostedStorage (iscsi or FC), I sent host deactivation to any host in HE env I see in vdsm.log error [storage.LVM] Removing VG mapping failed: Could not remove mapping:

Version-Release number of selected component (if applicable):
ovirt-engine-4.4.3.8-0.1.el8ev.noarch
vdsm-4.40.35-1.el8ev.x86_64

How reproducible:100% on HE env with blocked HostedStorage (iscsi or FC)


Steps to Reproduce:

1. 
POST https://{{host}}/ovirt-engine/api/hosts/6c3b8522-8ea8-4e6e-a331-3bcd334db6df/deactivate
<action>
    <async>true</async>
    <grace_period>
        <expiry>10</expiry>
    </grace_period>
</action>

Actual results:
The host is deactivated after this and no errors in engine.log.
Though not sure that such error in vdsm doesn't cause subsequent problem
