Ubuntu 虚拟机下挂载来自群晖的硬盘
保险的做法是把硬盘通过SATA挂到电脑上，不用通过硬盘盒再通过USB挂到电脑上，通过硬盘盒有可能会出现无法正确识别分区的问题。错误情况类似下面：[1]
# gdisk -l /dev/sdb GPT fdisk (gdisk) version 0.8.10 Warning! Disk size is smaller than the main header indicates! Loading secondary header from the last sector of the disk! You should use 'v' to verify disk integrity, and perhaps options on the experts' menu to repair the disk. Caution: invalid backup GPT header, but valid main header; regenerating backup header from main header. Warning! One or more CRCs don't match. You should repair the disk! Partition table scan: MBR: protective BSD: not present APM: not present GPT: damaged **************************************************************************** Caution: Found protective or hybrid MBR and corrupt GPT.

在虚拟机上新加硬盘，把整块群晖硬盘加入到虚拟机。
在 Ubuntu 中安装 mdadm 和 lvm2。[2][3]
再启动 Ubuntu 后，群晖硬盘上的数据分区会自动加载，但系统分区需要手动加载。
加载系统分区需要执行以下命令：[4]
mkdir /mnt/syno mount -t ext4 /dev/sdb1 /mnt/syno
如果不确定分区号，执行以下命令查看：
lsblk
