1、原/dev/sdb大小为500GB，通过VMware配置增加到1000GB
2、将/dev/sdb全部空间分配给/dev/sdb1
[root@hlht-test ~]# umount /u01
[root@hlht-test ~]# fdisk /dev/sdb
WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
switch off the mode (command 'c') and change display units to
sectors (command 'u').

3、调整分区
e2fsck -f /dev/sdb1 #检查分区信息
resize2fs /dev/sdb1 #调整分区大小
[root@hlht-test ~]# e2fsck -f /dev/sdb1
e2fsck 1.43-WIP (20-Jun-2013)
第一步: 检查inode,块,和大小
第二步: 检查目录结构
第3步: 检查目录连接性
Pass 4: Checking reference counts
第5步: 检查簇概要信息
/dev/sdb1: 57349/32768000 files (0.9% non-contiguous), 130385544/131070310 blocks
[root@hlht-test ~]# resize2fs /dev/sdb1
resize2fs 1.43-WIP (20-Jun-2013)
Resizing the filesystem on /dev/sdb1 to 262142637 (4k) blocks.
The filesystem on /dev/sdb1 is now 262142637 blocks long.
[root@hlht-test ~]# mount /dev/sdb1 /u01
[root@hlht-test ~]# df -h
