Mounting synology disks in ubuntu

I have some files on synology disk that I would like to recover with extundelete. I have mounted the raid1 setup. So on the disk is two raid storages (md2 and md3) and they are connected to one with lvm. I try to get the lvm going. I think it doesn't like the md2p1. I tried to mount md2p1, but it doesn't mount, so I thnik it's some garbage. How could I make that work that LVM would find the other device?

sudo lsblk -o name,uuid,mountpoint
