用fdisk进行分区挂载也可以哈，也比较简单fdisk /dev/vdb按步骤来即可

设置开机挂载

将挂载信息添加到fstab里即可, 操作前先备份

cp -r /etc/fstab /etc/fstab.20220927

UUID方式(常见)

# 查看ID
blkid /dev/vdb
/dev/vdb: UUID="5430aae0-55fa-4695-b8c9-7989035663f3" BLOCK_SIZE="4096" TYPE="ext4"
# fstab新增
UUID=5430aae0-55fa-4695-b8c9-7989035663f3 /data ext4 defaults 0 0

云硬盘(轻量推荐)

# 查看ID
ls /dev/disk/by-id/virtio-disk-*
# fstab新增
/dev/disk/by-id/virtio-disk-<ID> /data ext4 defaults 0 0
