本文执行命令为：abysw blog 硬盘挂载
===================以下为编写内容=================================
_ 项目需求：挂载新硬盘到服务器
_ 操作系统：CentOS Linux release 7.9.2009 (AltArch)
_ CPU：鲲鹏920 48核 2.6GHZ 2路
_ 内存：2T
_ 描述：由于项目需要，新买两个机械硬盘，需要挂载为一个阵列。
=================================================================
新建/dev/sdb 的磁盘标签类型为 GPT
parted /dev/sdb mklabel gpt
将/dev/sdb 整个空间分给同一个分区
parted /dev/sdb mkpart primary 0 100%
新建/dev/sdc 的磁盘标签类型为 GPT
parted /dev/sda mklabel gpt
将/dev/sdc 整个空间分给同一个分区
parted /dev/sda mkpart primary 0 100%

这里我没有输入创建名，默认为lvol0
fdisk -l 找到新创建的盘

格式化：
mkfs -t ext4 /dev/mapper/abysw-lvol0
再挂载，搞定了。
- 题外话：现在国产机器也算不错了，conda也有较好的支持。
