實驗01磁盤分區

?????實驗目標

?????????為虛擬機添加一塊80GB、SCSI接口的硬盤

?????????劃分2個20GB的主分區剩余作為擴展分區

?????????新建2個邏輯分區分別為2GB、10GB

?????????將第1個邏輯分區的類型改為SWAPID 82

?????????將第2個邏輯分區的類型改為VFATID b

?????????確認分區無誤后保存退出

?????????使用partprobe識別新的分區表?? 【最好是重啟一次】

?????實驗環境

在虛擬機Linux系統下

?????實驗步驟

一、環境準備

1.在虛擬關機狀態下添加一塊80G、SCSI硬盤

2. 使用“fdisk”命令查看新添加硬盤的屬性

[root@localhost ~]# fdisk -l /dev/sdb

Disk /dev/sdb: 85.8 GB, 85899345920bytes

255 heads, 63 sectors/track, 10443cylinders

Units = cylinders of 16065 * 512 =8225280 bytes

?

Disk /dev/sdb doesn't contain a validpartition table

?

3.劃分分區利用“fdisk”命令進入分區劃分模式

?[root@localhost~]# fdisk /dev/sdb

4.劃分2個20G的主分區剩余的為擴展分區可以通過m查看幫助信息

Command (m for help): m

Command action

??a?? toggle a bootable flag

??b?? edit bsd disklabel

??c?? toggle the dos compatibilityflag

??d?? delete a partition

??l?? list known partition types

??m?? print this menu

??n?? add a new partition

??o?? create a new empty DOSpartition table

??p?? print the partition table

??q?? quit without saving changes

??s?? create a new empty Sun disklabel

??t?? change a partition's system id

??u?? change display/entry units

??v?? verify the partition table

??w?? write table to disk and exit

??x?? extra functionality (expertsonly)

Command (m for help): n??????? //n為創建新分區的命令

Command action

??e?? extended???????????? //e代表擴展分區

??p?? primary partition (1-4) // p代表主分區

p

Partition number (1-4): 1?????????? //數字代表分區號

First cylinder (1-10443, default 1): //默認柱面起始編碼

Using default value 1

Last cylinder or +size or +sizeM or+sizeK (1-10443, default 10443): +20G???????????????? //設置分區大小“+”必須帶

Command (m for help): n

Command action

??e?? extended

??p?? primary partition (1-4)

p

Partition number (1-4): 2

First cylinder (2434-10443, default2434):

Using default value 2434

Value out of range.

Last cylinder or +size or +sizeM or+sizeK (2434-10443, default 10443): +20G

Command (m for help): n

Command action

??e?? extended

??p?? primary partition (1-4)

e

Partition number (1-4): 3

First cylinder (4867-10443, default4867):

Using default value 4867

Last cylinder or +size or +sizeM or+sizeK (4867-10443, default 10443): ?//若不設置大小默認剩余空間全部分給此分區

Using default value 10443

4. 在擴展分區中創建第1個2G邏輯分區并且修改分區類型為SWAPID 82

Command (m for help): n

Command action

??l?? logical (5 or over)? //l代表邏輯分區

??p?? primary partition (1-4) //由于只是3個主分區這里還是會顯示你是否建立主分區若是4個則不顯示

l

First cylinder (4867-10443, default4867):

Using default value 4867

Last cylinder or +size or +sizeM or+sizeK (4867-10443, default 10443): +2G

?

Command (m for help): t?? //t表示修改分區類型的命令

Partition number (1-5): 5

Hex code (type L to list codes): 82? //為swap的ID號

Changed system type of partition 5 to82 (Linux swap / Solaris)

?

5.在擴展分區中創建第2個10G邏輯分區并且修改分區類型為VFATID b

Command (m for help): n

Command action

??l?? logical (5 or over)

??p?? primary partition (1-4)

l

First cylinder (5111-10443, default5111):

Using default value 5111

Last cylinder or +size or +sizeM or+sizeK (5111-10443, default 10443): +10G

?

Command (m for help): t

Partition number (1-6): 6

Hex code (type L to list codes): b //b為vfat的ID號

Changed system type of partition 6 to b(W95 FAT32)

??6.確認劃分正確后保存退出

Command (m for help): w? //w為保存退出 q代表退出不保存

The partition table has been altered!

?

Calling ioctl() to re-read partitiontable.

?

WARNING: If you have created or modifiedany DOS 6.x

partitions, please see the fdisk manualpage for additional

information.

Syncing disks.

?????結果驗證

可以使用partprobe識別新的分區若還是無法顯示重啟

[root@localhost~]# fdisk -l /dev/sdb

?

Disk /dev/sdb: 85.8 GB, 85899345920bytes

255 heads, 63 sectors/track, 10443 cylinders

Units = cylinders of 16065 * 512 =8225280 bytes

?
