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
