description: 进行sudo fdisk -l查看机器上都插了哪些安装盘，看到/dev/sda，并且没有进行分区。这个时候是没有挂载的，运行如下命令：sudo parted /dev/sda #进入partedmklabel gpt #将磁盘设置为gpt格式，mkpart logical 0 -1 #将磁盘所有的容量设置为gpt格式print #查看分区结果quit #退出root@XXX:~# sudo parted /dev/sda GNU Parted 3.2 Using /dev/sda Welcome to GNU Parted! Type 'help' to view a list of commands. (parted) mklabel gpt Warning: The existing disk label on /dev/sda will be destroyed and all data on this disk will be lost. Do you want to continue? Yes/No? no (parted) mkpart logical 0 -1 Warning: The resulting partition is not properly aligned for best performance. Ignore/Cancel? ingnore parted: invalid token: ingnore Ignore/Cancel? ignore (parted) print Model: Phi H1 (scsi) Disk /dev/sda: 1000GB Sector size (logical/physical): 512B/512B Partition Table: gpt Disk Flags: Number Start End Size File system Name Flags 1 17.4kB 1000GB 1000GB logical (parted) quit这个时候应该是默认进行分了一个/dev/sda1这个分区运行sudo mkfs.ext4 -F /dev/sda1 将刚刚分出来的sda1格式化为ext4的格式，然后就可以设置开机自动挂载了。root@XXX:~# sudo mkfs.ext4 -F /dev/sda1 mke2fs 1.44.1 (24-Mar-2018) Suggestion: Use Linux kernel >= 3.18 for improved stability of the metadata and journal checksum features.
