挂載硬碟

1.添加磁盤，檢視磁盤狀況

[root@db1/]#fdisk-l

Disk/dev/sda:10.7GB,10737418240bytes

255heads,63sectors/track,1305cylinders

Units=cylindersof16065*512=8225280bytes

DeviceBootStartEndBlocksIdSystem

/dev/sda1*15113059277537+83Linux

/dev/sda211501204843+82Linuxswap

Partitiontableentriesarenotindiskorder

Disk/dev/sdb:5368MB,5368709120bytes

255heads,63sectors/track,652cylinders

從查詢結果看出，多了一個/dev/sdb的盤

2.用fdisk對/dev/sdb進行分區

[root@db1/]#fdisk/dev/sdb

Command(mforhelp):n

Commandaction

eextended

pprimarypartition(1-4)

p

Partitionnumber(1-4):1

Firstcylinder(1-652,default1):

Usingdefaultvalue1

Lastcylinderor+sizeor+sizeMor+sizeK(1-652,default652):

Usingdefaultvalue652

Command(mforhelp):w

Thepartitiontablehasbeenaltered!

Callingioctl()tore-readpartitiontable.

Syncingdisks.

再次檢視分區情況，多出來一個/dev/sdb1的區，這個1是我們在前面指定的，如果我們指定2，就變成sdb2了。

/dev/sdb116525237158+83Linux

[root@db1/]#

如果建立完之後，/proc/partitions檢視不到對應的分區，使用parprobe指令重新整理一下就可以了：

[root@web1~]#cat/proc/partitions

majorminor#blocksname

80175825944sda

811020096sda1

8230716280sda2

838193150sda3

[root@web1~]#partprobe/dev/sda

84135893835sda4

[root@web1~]#

3.格式化/dev/sdb1分區

[root@db1/]#mkfs-text3/dev/sdb1

mke2fs1.35(28-Feb-2004)

Filesystemlabel=

OStype:Linux

Blocksize=4096(log=2)

4.建立目錄并将/dev/sdb1挂在到該目錄下

[root@db1/]#ls

backupdevinitrdmediaoptsbinsysusr

binetclibmiscprocselinuxtftpbootvar

boothomelost+foundmntrootsrvtmp

[root@db1/]#mkdir/u01

backupdevinitrdmediaoptsbinsysu01

binetclibmiscprocselinuxtftpbootusr

boothomelost+foundmntrootsrvtmpvar

[root@db1/]#mount/dev/sdb1/u01

5.驗證挂載是否成功

[root@db1/]#df-k

Filesystem1K-blocksUsedAvailableUse%Mountedon

/dev/sda191317727066884160101282%/

none45425604542560%/dev/shm

/dev/sdb151548524304048499561%/backup

6.設定開機自動挂載

[root@db1/]#vi/etc/fstab

#Thisfileiseditedbyfstab-sync-see'manfstab-sync'fordetails
