Ubuntu 无法识别 Dell Poweredge R720 上的完整 RAID 磁盘

安装时，系统只允许我在 3.5TB 的硬盘上进行安装。但系统配置了 3625GB 的存储空间。

键入时，sudo fdisk -l响应如下：

sudo lshw -class storage -class disk这是可以看到完整存储容量的信息。

我不确定为什么系统无法识别完整的 3892GB 存储空间，也不太确定从哪里开始。任何帮助我都会很感激我对这个操作系统不太熟悉，所以对于任何格式错误我深表歉意，我愿意向任何愿意提供帮助的人提供更多信息。谢谢 :)

这是常见的营销“技巧”。

为了销售，供应商使用基数 10^3 除数（1000），而计算机使用基数 2^10 除数（1024）：

电脑：

3892716765184/1024/1024/1024/1024
3.54
3892716765184/1024/1024/1024
3625.37

营销：

3892716765184/1000/1000/1000/1000
3.89
3892716765184/1000/1000/1000
3892.71

您会看到 显示的字节数fdisk与 显示的大小完全相同lshw，只是转换方式不同。
