aliyun ecs 挂载云盘
先购买一个云盘 500G大小
查看硬盘情况fdisk -l
查看是否有一个 /dev/xvdb 或者 数据盘大小与你要挂载一致的硬盘

Disk /dev/xvdb doesn't contain a valid partition table
执行分区
fdisk /dev/xvdb
;对数据盘进行分区;根据提示,依次输入“n”,“p”“1”,两次回车,“wq”,分区就开始了,很快就会完成。
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0x5c273d61.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

查看硬盘信息
fdisk -l
查看新的分区。新分区 xvdb1 已经创建好。如下面示例中的/dev/xvdb1

有两种情况,
- 你这个数据盘是新购买的,以前没有用过(没有存储过数据),那么就要对其进行格式化,使用
mkfs.ext3 /dev/xvdb1
命令。 - 第二种,如果你之前就有数据盘,只是你把系统盘重置了,需要将数据盘再次挂载到重置后的系统上,那么就不要对其格式化(跳过此步骤),直接执行后面的步骤挂载就可以了。

挂载到 /mnt
前提是你已经创建了这个目录(创建目录的命令是mkdir)。以下命令写入新分区信息
echo '/dev/xvdb1 /mnt ext3 defaults 0 0' >> /etc/fstab
查看,出现以下信息就表示写入成功。
cat /etc/fstab
UUID=af414ad8-9936-46cd-b074-528854656fcd / ext4 errors=remount-ro 0 1
/dev/xvdb /mnt ext3 defaults 0 0
挂载新分区
使用mount -a
挂载,df -h
命令查看,出现以下信息就说明挂载成功,可以开始使用新的分区了。
df -h
