linux虚拟服务器新增磁盘怎么挂载,如何在vmware虚拟机Linux中增加硬盘的方法(教程)...
前期準備:創建虛擬硬盤
1、關閉VM中正在運行的虛擬系統;
2、在虛擬系統名稱上點右鍵-》Virtual Machine Settings;
3、在Hardware頁點“Add”-》Add a hard disk-》Create a new virtual disk-》SCSI(recommended)-》分配空間大小-》OK;
4、可以看見Hardware中出現了一塊新的硬盤Hard Disk 2。
實施階段:對虛擬硬盤進行分區和格式化
1、查看目前系統上有幾塊硬盤
[iyunv@cncmail data1]# fdisk -l
第一塊硬盤信息
Disk /dev/sda: 36.4 GB, 36401479680 bytes
255 heads, 63 sectors/track, 4425 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot???? Start??????? End???? Blocks??? Id?? System
/dev/sda1??? *????????? 1??????? 255??? 2048256??? 83?? Linux
/dev/sda2??????????? 256?????? 1530?? 10241437+?? 83?? Linux
/dev/sda3?????????? 4296?????? 4425??? 1044225??? 82?? Linux swap
/dev/sda4?????????? 1531?????? 4295?? 22209862+??? f?? Win95 Extd (LBA)
/dev/sda5?????????? 1531?????? 2805?? 10241406??? 83?? Linux
/dev/sda6?????????? 2806?????? 4295?? 11968393+?? 83?? Linux
Partition table entries are not in disk order
第二塊硬盤信息
Disk /dev/sdb: 36.7 GB, 36703918080 bytes ## 這里發現/dev/sdb,容量36.7G,切未被分區
255 heads, 63 sectors/track, 4462 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk /dev/sdc doesnt contain a valid partition table
第二塊硬盤沒有分區表
[iyunv@linux root]# fdisk /dev/sdb
對第二塊硬盤進行分區
The number of cylinders for this disk is set to 4462.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
Command (m for help): m
Command action
a??? toggle a bootable flag
b??? edit bsd disklabel
c??? toggle the dos compatibility flag
d??? a partition
l??? list known partition types
m??? print this menu
n??? add a new partition
o??? create a new empty DOS partition table
p??? print the partition table
q??? quit without saving changes
s??? create a new empty Sun disklabel
t??? change a partitions system id
u??? change display/entry units
v??? verify the partition table
w??? write table to disk and exit
x??? extra functionality (experts only)
Command (m for help): p
## 打印出目前該硬盤下的分區列表
Disk /dev/sdb: 36.7 GB, 36703918080 bytes
255 heads, 63 sectors/track, 4462 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot???? Start??????? End???? Blocks??? Id?? System
Command (m for help): n
## 增加一個分區
Command action
e??? extended
p??? primary partition (1-4)
## 因為通常選擇主分區,所以這里打一個p
p
Partition number (1-4): 1???? ## 這里因為是第一個分卻,所以只選擇1,如果是第二個分區,則選擇2,依次類推
First cylinder (1-4462, default 1): ## 新分區起始的磁盤塊數
Using default value 1
Last cylinder or +size or +sizeM or +sizeK (1-4462, default 4462): 如果要分區10G,這里可以直接輸入:+10240M,因為這里要全部使用硬盤空間,則用默認
Using default value 4462
Command (m for help): p
Disk /dev/sdb: 36.7 GB, 36703918080 bytes
255 heads, 63 sectors/track, 4462 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot???? Start??????? End???? Blocks??? Id?? System
/dev/sdb1????????????? 1?????? 4462?? 35840983+?? 83?? Linux
## 這里第一個分區已經分好了,接下去得把這個分區寫入硬盤,用w
Command (m for help): w
The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.
下面的工作就是對該硬盤進行格式,我這里是格式化成ext3
[iyunv@linux root]# mkfs.ext3 /dev/sdb1 (這里原來的命令是:mke2fs -j /dev/sdb1,試了一下不成???????? 功,改了)
mke2fs 1.32 (09-Nov-2002)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
4480448 inodes, 8960245 blocks
448012 blocks (5.00%) reserved for the super user
First data block=0
274 block groups
32768 blocks per group, 32768 fragments per group
16352 inodes per group
Superblock backups stored on blocks:
32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208,
4096000, 7962624
Writing inode tables: done
Creating journal (8192 blocks): done
Writing superblocks and filesystem accounting information: done
This filesystem will be automatically checked every 23 mounts or
180 days, whichever comes first.?? Use tune2fs -c or -i to override.
檢查一下,是否已經格式好
[iyunv@linux root]# fdisk -l
Disk /dev/sda: 36.4 GB, 36401479680 bytes
255 heads, 63 sectors/track, 4425 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot???? Start??????? End???? Blocks??? Id?? System
/dev/sda1??? *????????? 1??????? 255??? 2048256??? 83?? Linux
/dev/sda2??????????? 256?????? 1530?? 10241437+?? 83?? Linux
/dev/sda3?????????? 4296?????? 4425??? 1044225??? 82?? Linux swap
/dev/sda4?????????? 1531?????? 4295?? 22209862+??? f?? Win95 Extd (LBA)
/dev/sda5?????????? 1531?????? 2805?? 10241406??? 83?? Linux
/dev/sda6?????????? 2806?????? 4295?? 11968393+?? 83?? Linux
Partition table entries are not in disk order
Disk /dev/sdb: 36.7 GB, 36703918080 bytes
255 heads, 63 sectors/track, 4462 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot???? Start??????? End???? Blocks??? Id?? System
/dev/sdb1????????????? 1?????? 4462?? 35840983+?? 83?? Linux
掛載虛擬硬盤
分區分好,也格式化好了,下面就是掛載
我把/dev/sdb1掛載到/data1下
[iyunv@linux root]# mkdir /data1?? ## 首先建立掛載的目錄data1
[iyunv@linux root]# mount /dev/sdb1 /data1 ##將sdb1掛載到data1
重啟系統之后,查看是否掛載成功:
[iyunv@linux data1]# df -h
文件系統?????????????? 容量?? 已用 可用 已用% 掛載點
/dev/sda1????????????? 2.0G?? 454M?? 1.4G?? 25% /
/dev/sda6?????????????? 12G??? 53M??? 11G??? 1% /bak
/dev/sdb1?????????????? 34G??? 33M??? 32G??? 1% /data1
none?????????????????? 250M????? 0?? 250M??? 0% /dev/shm
/dev/sda2????????????? 9.7G?? 1.5G?? 7.7G?? 17% /usr
/dev/sda5????????????? 9.7G?? 8.6G?? 559M?? 95% /var
這里看到/dev/sda6?????????????? 12G??? 53M??? 11G??? 1% /bak
說明已經掛載成功了。到根目錄“/”下可以查看到這個掛載好的data1。
