我们有一个 Synology NAS 设备，它为大型磁盘阵列提供 iSCSI 服务。我们更换了几个驱动器，并且“修复...”花了很长时间才完成，现在我们的 Ubuntu 10.04.4 LTS 服务器没有安装存储。当我启动 open-iscsi 服务时，/dev/sda 设备被创建并且没有分区，而它过去是作为 /dev/sda1 安装的。如果我尝试手动安装：
# 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
Synology GUI 显示空间使用量为 7TB，这是我的节点配置：

我对 iscsi 完全陌生，我已经在 Synology 中验证了目标。它确实在本地系统上连接并创建了设备，但没有分区。还有其他需要吗？
