Hello !
It seems like ceph-volume from Ceph Pacific 16.2.11 has a problem with
same LV names in different VG.
I use ceph-ansible (stable-6), with a pre-existing LVM configuration.
Here's the error :
TASK [ceph-osd : include_tasks scenarios/lvm.yml]

If I execute the ceph-volume command myself on one target host, I get :
fcadmin@fidcllabs-sto-01:~$ sudo ceph-volume --cluster ceph lvm list
data-vg1/data-lv1 --format=json
--> RuntimeError: Filters {'lv_name': 'data-lv1'} matched more than 1
LV present on this host.
My LVs :

Yes, all data LVs have the same name, but under a different VG.
I look at the tracker but don't find a clear corresponding issue.
I will certainly open one if there's nothing known around here.
