[ovirt-users] Add FC domain failed - but reported as used

[Roberto Nunin]

I've tried to add a second FC data domain to our oVirt remote infra, built
with 6 hosts in remote and 4 local, where hosted-engine is running.

Currently, we are using  4.0.1.1-1.el7.centos.

After FC storage setup (zoning/masking), tried to add the new volume to the
remote DC.

Process was failing with:

2017-10-11 12:57:31,174 ERROR

After this attempt, I've double checket that all 6 hosts have identified
the new volume. All are ok.

Another attempt to add the volume to the remote DC, was failing blocking me
to chosse the volume ID into the GUI interface, because "the LUN is already
part of a Storage DOmain".

I think that something is still marking as used the new volume into the
host-engine DB, even if it isn't available into the GUI interface.
If this could be the reason, how to correctly manage this issue ? (apart
update the entire installation, planned :) )

Thanks in advance
