阿里服务器申请到后,即便申请了数据盘,系统里面也没有自动配置上,看到的只有系统盘20GB,需要手动配置数据盘。

可以看到里面有一个300GB的硬盘/dev/xvdb,但是没有其他信息,因为没有格式化。
OK,现在手动格式化这个硬盘。
fdisk /dev/xvdb
在 fdisk 程序里输入 n, 然后输入 p,在后面分区开头和结尾选择里直接回车格式化位一个分区;
然后输入 p 可看到分区信息,再输入 w 写入分区配置,然后开始显示格式化进度条,结束后就OK了。

The partition table has been altered!

[root@iZcmake-2.8.5]# fdisk -l
挂载分区到目录:
[root@iZcmake-2.8.5]# mkdir -pv /data
mkdir: created directory `/data'
[root@iZcmake-2.8.5]# mount /dev/xvdb1 /data
如果这一步提示错误:
mount: you must specify the filesystem type
那是因为没有格式化分区导致的,重新格式化再mount就OK:
mkfs.ext3 /dev/xvdb1
mount /dev/xvdb1 /data
[root@iZcmake-2.8.5]#
将配置写入fstab:
vim /etc/fstab
末尾增加一行:
/dev/xvdb1 /data ext3 defaults 1 1
然后保存退出即可。
