  今天为了挂载文件系统,对磁盘进行分区,磁盘大小3.6TB。
  使用fdisk对磁盘分区完成之后,查看如下:
Disk /dev/sdb: 3598.9 GB, 3598914158592 bytes
255 heads, 63 sectors/track, 437543 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1           234976  1887444688+  83  Linux
/dev/sdb2          234977      267349   260036122+   5  Extended

   发现最大只能识别260036122Blocks,3.6TB的磁盘没有完全分完,经查阅资料,使用fdisk进行分区最大只能识别2TB,于是采用parted进行分区。
[root@localhost /]# parted /dev/sdb

corrupted -- possibly by a program that doesn't understand GPT partition tables.  Or perhaps you deleted the GPT table, and are now using an msdos partition table.  Is this
a GPT partition table?

Warning: /dev/sdb contains GPT signatures, indicating that it has a GPT table.  However, it does not have a valid fake msdos partition table, as it should.  Perhaps it was

[root@localhost dev]$cd /dev
[root@localhost dev]$ ls |grep sdb
sdb
sdb1
sdb2
  分区已经完成,下一步可以进行格式化并挂载文件系统
mkfs -t ext4 /dev/sdb1
mkfs -t ext4 /dev/sdb2
