运维问题.解决亚马逊AWS云EC2主机申请时加大根分区启动实例后不识别问题?

问题原因:

申请AWS EC2时按照向导,在选择存储时默认根分区硬盘大小为8G,这时候可以根据自己需要输入一个合适的数字,例如50G,完成启动EC2后登录机器,使用命令

解决办法:

[root@xm-server-50007 ~]# resize2fs /dev/xvde

resize2fs 1.41.12 (17-May-2010)

Filesystem at /dev/xvde is mounted on /; on-line resizing required

old desc_blocks = 1, new_desc_blocks = 4

Performing an on-line resize of /dev/xvde to 13107200 (4k) blocks.

The filesystem on /dev/xvde is now 13107200 blocks long.
