Linux下挂载4T大小usb硬盘的经历

【注】都是从网络上学来的！只是我记录了一下，免的将来又要挂盘的时候还要一通忙活！
（用ntfs-3g没有挂成功！）
1、先去win7下进入磁盘管理里在这个大盘上单击右键，转换成GPT分区格式！
2、挂到Linux机器上，用fdisk -l看看！能看到。（但不用它）
3、下载最新的parted安装。
4、用parted挂载。
5、格式化成ext3文件系统。
6、mount 这个大盘。（机器自动进行的。）
7、在启动机器的状态下，修改/etc/fstab文件。

机器是rehl5，uname -r显示是：
[root@pc03 ~]# uname -r
2.6.18-308.el5

下载最新的parted是3.1

[root@pc03 ~]# xz -d parted-3.1.tar.xz
[root@pc03 ~]# tar xvf parted-3.1.tar
[root@pc03 ~]# cd parted-3.1
[root@pc03 parted-3.1]#./configure
[root@pc03 parted-3.1]#make
[root@pc03 parted-3.1]#make install
[root@pc03 parted-3.1]#reboot

插上usb的盘：
[root@pc03 ~]# fdisk -l

[root@pc03 ~]#mkfs -t ext3 /dev/sdc

格式化完成后，还没有mount，机器自己就认识了这块盘。像u盘一样！
本来到此很顺利的就完成了！
结果我去/etc/fstab中加了一行
/dev/sdc         /data2         ext3    default    1 2
机器再启动就启动不起来了！提示我输入root密码进入维护状态。按ctrl+D进去普通启动，可是如果按了ctrl+D就是重新启动。如同进入死循环！只有输入root的密码进入维护状态！

又去网络上查找，结果找到一条：在维护状态下进入可读写状态：

（repair filesystem）1#cat /etc/fstab

（repair filesystem）2#mount -o remount ,rw /dev/sda1/
（repair filesystem）3#vi /etc/fstab

赶紧把画蛇添足的那一行删除！
重新启动，重新parted操作一遍，机器自动看到了：

[root@pc03 ~]# df -k

就算我成功了！
只是每一次只要重新启动了机器都要parted一回！
