We have a Synology NAS device which provides iSCSI services to a large disk array. We had a couple of drives replaced and it took long for the "Repairing..." to finish and now our Ubuntu 10.04.4 LTS server is not mounting the storage. When I start the open-iscsi service, the /dev/sda device gets created and has no partitions when it used to mount as /dev/sda1. If I try to mount manually:
# iscsi in /etc/fstab
UUID=82d94989-fabc-49f6-a9ef-e0bd9bc218c3 /srv/samba/video ext4 defaults,auto,_netdev,acl 0 0
robert@news-storage:/etc/iscsi$ sudo mount /srv/samba/video
mount: special device UUID=82d94989-fabc-49f6-a9ef-e0bd9bc218c3 does not exist
The Synology GUI shows space usage of 7TB, here is my config for the node:

I am completely new to iscsi, I have verified the target in Synology. It does connect and create the device on the local system, but no partition. Is there something else needed?
