我是gce的新手，并试图扩展我的/ dev / sda磁盘。 我怎样才能做到这一点？ 我已经为我的实例添加了200Gb磁盘，然后在其上创建文件系统。 这是fdisk -lu结果：
Disk /dev/sda: 10.7 GB, 10737418240 bytes
4 heads, 32 sectors/track, 163840 cylinders, total 20971520 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disk identifier: 0x0004a990
Device Boot Start End Blocks Id System
/dev/sda1 2048 20969472 10483712+ 83 Linux
Disk /dev/sdb: 214.7 GB, 214748364800 bytes
86 heads, 25 sectors/track, 195083 cylinders, total 419430400 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disk identifier: 0x70f99a87
Device Boot Start End Blocks Id System
/dev/sdb1 2048 419430399 209714176 83 Linux
但是当我运行df -h时，结果是：
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 9.9G 998M 8.4G 11% /
tmpfs 851M 0 851M 0% /dev/shm
我该怎么办？ 请帮忙.. 感谢..
