这是一个命令行界面下的磁盘分区工具（可能是 fdisk 或 parted），提示你选择分区类型。你需要根据你的需求和磁盘情况进行选择。一般来说，如果你只需要简单地将整个磁盘分成一个分区，就选择 primary。如果你需要更多的分区，就选择 extended，再在其中创建逻辑分区。如果你不确定该选择什么，可以输入 p 查看当前磁盘分区情况。

为你的虚拟机添加一块磁盘,并且新建六个分区,六个分区要求如下: sdb1为主分区,500M的容量,文件格式为ext3; sdb2为主分区,容量不限,文件格式为FAT; sdb3为主分区,容量不限,文件格式为FAT; sdb4为扩展

分区,容量不限,包含两个逻辑分区; 逻辑分区sdb5的容量为1G,文件格式为ext4; 逻辑分区sdb6的容量为2G,文件格式为NTFS。

首先，你需要将虚拟机关机，然后在虚拟机管理软件（如VMware）中添加一块磁盘，这里假设添加的是/dev/sdb。

接下来，你需要使用fdisk或parted工具对新添加的磁盘进行分区。

1. 使用fdisk对/dev/sdb进行分区：

sudo fdisk /dev/sdb

输入`n`创建新分区，按照提示输入分区编号（1-4）和分区大小（500M），然后设置文件系统类型为ext3。

/dev/sdb6       12584960 14659455  2074496    2G  7 HPFS/NTFS/exFAT

2. 使用parted对/dev/sdb进行分区：

sudo parted /dev/sdb

输入`mklabel msdos`创建MBR分区表，然后使用`mkpart`命令创建分区。

(parted) mklabel msdos
(parted) mkpart primary ext3 1M 501M
(parted) mkpart primary fat32 501M 100%
(parted) mkpart primary fat32 100% 100%
(parted) mkpart extended 100% 100%
(parted) mkpart logical ext4 100% 25%
(parted) mkpart logical ntfs 25% 75%
(parted) quit

3. 格式化分区：

sudo mkfs.ext3 /dev/sdb1
sudo mkfs.vfat /dev/sdb2
sudo mkfs.vfat /dev/sdb3
sudo mkfs.ext4 /dev/sdb5
sudo mkfs.ntfs /dev/sdb6

4. 挂载分区：

sudo mkdir /mnt/sdb1
sudo mkdir /mnt/sdb2
sudo mkdir /mnt/sdb3
sudo mkdir /mnt/sdb5
sudo mkdir /mnt/sdb6

sudo mount /dev/sdb1 /mnt/sdb1
sudo mount /dev/sdb2 /mnt/sdb2
sudo mount /dev/sdb3 /mnt/sdb3
sudo mount /dev/sdb5 /mnt/sdb5
sudo mount /dev/sdb6 /mnt/sdb6

至此，你已经成功的为虚拟机添加了一个磁盘，并且新建了六个分区。

linux系统，创建/dev/sdb1主分区、创建/dev/sdb2扩展分区、创建/dev/sdb5逻辑分区，将创建的分区格式化为ext4文件系统，挂载三个分区

您可以按照以下步骤在Linux系统中完成上述任务：

1. 创建/dev/sdb1主分区：可以使用fdisk命令或者parted命令来对磁盘进行分区，例如：

   sudo fdisk /dev/sdb
   Command (m for help): n
   Partition type
      p   primary (0 primary, 0 extended, 4 free)
      e   extended (container for logical partitions)
   Select (default p): p
   Partition number (1-4, default 1): 1
   First sector (2048-41943039, default 2048):
   Last sector, +sectors or +size{K,M,G,T,P} (2048-41943039, default 41943039):
   Command (m for help): w

2. 创建/dev/sdb2扩展分区：同样可以使用fdisk命令或者parted命令来对磁盘进行分区，例如：

   sudo fdisk /dev/sdb
   Command (m for help): n
   Partition type
      p   primary (1 primary, 0 extended, 3 free)
      e   extended (container for logical partitions)
   Select (default p): e
   Partition number (2-4, default 2):
   First sector (41943040-41943039, default 41943040):
   Last sector, +sectors or +size{K,M,G,T,P} (41943040-41943039, default 41943039):
   Command (m for help): w

3. 创建/dev/sdb5逻辑分区：在/dev/sdb2扩展分区中创建逻辑分区，例如：

   sudo fdisk /dev/sdb
   Command (m for help): n
   Partition type
      p   primary (1 primary, 0 extended, 2 free)
      l   logical (numbered from 5)
   Select (default p): l
   Partition number (5-128, default 5):
   First sector (41945088-41943039, default 41945088):
   Last sector, +sectors or +size{K,M,G,T,P} (41945088-41943039, default 41943039):
   Command (m for help): w

4. 格式化分区为ext4文件系统：可以使用mkfs命令，例如：

   sudo mkfs.ext4 /dev/sdb1
   sudo mkfs.ext4 /dev/sdb5

5. 创建挂载点目录：例如，在根目录下创建三个目录，分别用来挂载三个分区：

   sudo mkdir /mnt/sdb1
   sudo mkdir /mnt/sdb2
   sudo mkdir /mnt/sdb5

6. 挂载分区：可以使用mount命令，例如：

   sudo mount /dev/sdb1 /mnt/sdb1
   sudo mount /dev/sdb2 /mnt/sdb2
   sudo mount /dev/sdb5 /mnt/sdb5

需要注意的是，挂载分区后，如果需要让分区在系统启动时自动挂载，可以在/etc/fstab文件中添加相应的记录。
