Reportedly [1], the kernel-nfs-server has a bug where we have overlap of filesystem identifiers using LVM volumes and their snapshots. We face this bug in manila LVM driver and Generic driver when we use cinder LVM driver. So, fix it generating unique UUID for all snapshots (only for LVM, because we cannot do it in Generic driver while we do not have "mount-snapshot" feature support there) and child volumes that will be exported as child shares.
