查看新插入的磁盘
使用指令 sudo fdisk -l 查看磁盘是否被操作系统正确识别
Disk /dev/sdc: 4.6 TiB, 5000981078016 bytes, 9767541168 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
格式化磁盘
这里将磁盘格式化为ext4格式
sudo mkfs.ext4 /dev/sdc
挂载
将磁盘挂载到指定目录以使用
sudo mount /dev/sdc ~/disk/disk2
开机自动挂载
root权限打开/etc/fstab文件，添加：
UUID=7c07bcbe-b2c5-47e6-be0e-f7ad8a70609b /home/gpu-server/disk/disk2 ext4 defaults 0 2
UUID代表磁盘的唯一id，可以通过以下指令获取
ls -l /dev/disk/by-uuid/
