Ubuntu升级硬盘如何连接旧硬盘

Question

我最近通过安装 1T 驱动器升级了家庭服务器，现在我想将旧驱动器连接到系统。我该怎么做？我知道旧驱动器有 2 个 ext2 分区，大约 500GB，在此列表中显示为 sda2。

lsblk shows sda2 mounted to boot
sda                         8:0    0 931.5G  0 disk 
├─sda1                      8:1    0     1M  0 part 
├─sda2                      8:2    0     1G  0 part /boot
└─sda3                      8:3    0 930.5G  0 part 
  └─ubuntu--vg-ubuntu--lv 253:0    0 930.5G  0 lvm  /

brw-rw---- 1 root disk 8, 16 Jun  3 13:39 /dev/sdb

fdisk -l:

mount -a -t ext2 /dev/sdb /media/old_drive/
mount the drive but not its partitions

ls -la /media/old_drive/
total 8
drwxr-xr-x 2 root root 4096 Jun  2 09:34 .
drwxr-xr-x 3 root root 4096 Jun  2 09:34 ..

我不知道接下来该去哪里:(
