Hello,
does anyone know if it's possible, using ovirt-shell or api, to list
every disk image residing on specific FC LUN?

Hi Amedeo,
I don't think that it's possible.
But if your storage domain contains only 1 FC lun, then listing the disks on this storage
domain will provide you the info.

Hi Meital and all,
unfortunately we have several luns, but we've lost one of them (and it's
not possible to recover it from the box), so we're looking to know what
images are residing on that lun due to remove those images from
db/engine gui...
using lvm command on hypervisor node it's possible to match lv name
still alive, with some id present on engine db or by ovirt-shell cmd
like "list disk --show-all" ?
thanks in advance

Hi Amedeo,
Was the LUN that was lost a separate storage domain? if it was, you can list all the disks
in the system and then filter the list for disks on that storage domain. for example, in
python sdk:
disks = api.disks.list()
[disk for disk in disks if disk.get_storage_domains().get_storage_domain().get_id() ==
fc_storage_domain_id]
Thanks,
Gadi Ickowicz

Hi Gadi,
no on that DC we have two storagedomains, each one of them has 2 LUNs,
(total 4 LUNs on two SD), and we have lost only one of them, so we have
one SD consistent and one SD broken without one lun.
To better understand what was happened, the lost LUN was effectively not
lost, but was inadvertently overwrite during new hypervisor instalation,
so it was not lost, and is still visible to hypervisor, but it's content
was wiped out / overwritten.
do you think that it's possible to match, by lvm command on hypervisor,
lv name still alive, with some id present on engine db or by ovirt-shell
cmd?
thanks in advance

Hi Amedeo,
Although I have not used this before, I found this answer[1] to a similar question online
which may help, it describes the usage of pvdisplay, vgdisplay and lvdisplay. These may
provide the information you need regarding where each LV is.
To match the lv to the actual disk you need to know the image ID that the LV (volume) is
part of, visible in the lv_tags field (IU_<image_uuid>) using:
lvs -o+lv_tags
Even with this, I do not know if you can recover the storage domain itself...
