/data 不够用了，咋办？

[root@mercury8] ~# /usr/local/etc/rc.d/nginx stop

代码:

Stopping nginx.

[root@mercury8] ~# umount /data

[root@mercury8] ~# fdisk -BI da1

代码:

******* Working on device /dev/da1 *******  fdisk: Class not found

用sysinstall 的 fdisk 察看能扩展到哪个扇区：超出没关系，会提示你正确的最大值。

A = Use Entire Disk G = set Drive Geometry C = Create Slice

D = Delete Slice Z = Toggle Size Units S = Set Bootable | = Expert m.

T = Change Type U = Undo All Changes W = Write Changes

Use F1 or ? to get more help, arrow keys to select.
