To see who has in charge the VG:
[root@f18ovn01 ~]# fuser /dev/013bcc40-5f3d-4394-bd3b-971b14852654/*
/dev/dm-83: 27445

/dev/dm-84: 27445

[root@f18ovn01 ~]# ps -wfp 27445

It was a vm for which I moved the disk and apparently I got error
about it but from the gui the disk was the new one (original disk was
on this sd...); see:
http://lists.ovirt.org/pipermail/users/2013-April/013847.html
So shutdown of the VM
[root@f18ovn01 ~]# fuser /dev/013bcc40-5f3d-4394-bd3b-971b14852654/*
[root@f18ovn01 ~]#
Now remove operation from gui gets:
Error while executing action Remove Storage Domain: Storage domain
cannot be reached. Please ensure it is accessible from the host(s).
So it seems I have a missing link but the actual structure is there:

I don't know if
existence of the link <--> SD associated to DC or what is
so I try to force destroy it
Message:

Approve
and I get it
Storage Domain DS6800_Z2_1601 was forcibly removed by admin@internal
vg is still there:
