Hi Zinovik,
Have you tried using the scan disks procedure[*] (which scans the domain
for unregistered floating disks)?
You can find it under 'Storage -> Domains -> Disks -> "Scan Disks"
button
(in the Kebab Menu)'.

I cannot even attach snapshot volume.
Disks scanning is available only for attached storage domains.
