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[root@iZcmake-2.8.5]# fdisk -l Disk /dev/xvda: 21.5 GB, 21474836480 bytes 255 heads, 63 sectors/track, 2610 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00078f9c Device Boot Start End Blocks Id System /dev/xvda1 * 1 2611 20970496 83 Linux Disk /dev/xvdb: 322.1 GB, 322122547200 bytes 255 heads, 63 sectors/track, 39162 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 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。
