我有一台 Ubuntu 20.04 服务器，愉快地运行 2 个 RAID1 阵列。
我有一堆旧磁盘，我想在决定是否在销毁之前进行备份之前检查它们。
我通过 SATA 转 USB 盒将磁盘连接到服务器。
有些磁盘是 RAID5 阵列的一部分，而我只有一个 USB 盒，所以我尝试（希望）至少安装它们以便能够检查内容 - 我只读取只读视图。
连接磁盘后lsblk给出：
sdf 8:80 0 465.8G 0 disk
├─sdf1 8:81 0 290.2M 0 part
├─sdf2 8:82 0 486.4M 0 part

├─sdf5 8:85 0 133.3M 0 part
└─sdf6 8:86 0 464.8G 0 part
我fdisk -l得到：
fdisk -l /dev/sdf

Partition 1 does not start on physical sector boundary.
Partition 2 does not start on physical sector boundary.
Partition 4 does not start on physical sector boundary.
Partition 5 does not start on physical sector boundary.
Partition 6 does not start on physical sector boundary.
在cat /proc/mdstat我看到：
Personalities : [raid1] [linear] [multipath] [raid0] [raid6] [raid5] [raid4] [raid10]
md123 : inactive sdf6[0](S)

我尝试扫描然后组装并安装：
mdadm --detail --scan /dev/md123
给出：
INACTIVE-ARRAY /dev/md123 metadata=0.90 UUID=9b990924:10915d87:0073689c:05407c1c
跑步mdadm --assemble --force /dev/md123 /dev/sdf6
mdadm: /dev/sdf6 is busy - skipping
尝试挂载：
mount /dev/md124 /mnt/usb/usb6
mount: /mnt/usb/usb6: can't read superblock on /dev/md124.
我尝试运行最重要的恢复，但它将相同类型的文件转储到文件夹中并且不保留名称。
foremost -dvT -i /dev/sdf6 -o /mnt/md0/share01/Backups/aa
我还能做什么来尝试安装磁盘以便获取内容？
我知道 RAID5 不能替代备份 - 但任何帮助都会很棒。
