resize2fs 1.41.12 (17-May-2010)
resize2fs: New size too large to be expressed in 32 bits

The lvdisplay and vgdisplay commands shows the logical volume size as 16TiB.

Resolution：

1、下载高版本e2fsprogs

wget  http://prdownloads.sourceforge.net/e2fsprogs/e2fsprogs-1.45.6.tar.gz

2、停止数据库/应用

3、tar -zxvf e2fsprogs-1.45.6.tar.gz

cd e2fsprogs-1.45.6

./configure

make

因为还有数据库环境，不想改变现有系统环境库版本，使用当前编译环境即可。下面是执行过程，根据文件系统大小，需要一些时间，执行前卸载挂载目录。
