Step 1. 查看硬碟資訊，發現有兩顆 /dev/vad 與 /dev/vab
[root@xxxxx tmp]# fdisk -lu
Disk /dev/vda: 53.7 GB, 53687091200 bytes
255 heads, 63 sectors/track, 6527 cylinders, total 104857600 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x0003a7b4
Device Boot Start End Blocks Id System
/dev/vda1 * 2048 104855551 52426752 83 Linux
Disk /dev/vdb: 536.9 GB, 536870912000 bytes
16 heads, 63 sectors/track, 1040253 cylinders, total 1048576000 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Step 2. 新增磁區
[root@xxxxx tmp]# fdisk /dev/vdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0x492efa4a.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
switch off the mode (command 'c') and change display units to
sectors (command 'u').
Command (m for help): m
Command action
a toggle a bootable flag
b edit bsd disklabel
c toggle the dos compatibility flag
d delete 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 partition's 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): n
Command action
e extended
p primary partition (1-4)
e
Partition number (1-4):1
First cylinder (1-1040253, default 1): default
Using default value 1
Last cylinder, +cylinders or +size{K,M,G} (1-1040253, default 1040253): default
Command (m for help): w
Step 3. 設定磁區格式 ext4
[root@xxxxx tmp]# mkfs -t ext4 /dev/vdb
mke2fs 1.41.12 (17-May-2010)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
Stride=0 blocks, Stripe width=0 blocks
32768000 inodes, 131072000 blocks
6553600 blocks (5.00%) reserved for the super user
.....
Step 4. 建立disk UUID
[root@xxxxx tmp]# tune2fs -U random /dev/vdb
tune2fs 1.41.12 (17-May-2010)
Step 5. 查看UUID
[root@xxxxx tmp]# blkid /dev/vdb
/dev/vdb: UUID="8217a44e-70f1-4f84-850d-c9e8f30ae5bb" TYPE="ext4"
Step 6. 註冊UUID
[root@xxxxx tmp]# vim /etc/fstab
UUID=b7aae0d4-268c-4b60-914a-f3b48e22819c / ext4 defaults 1 1
tmpfs /dev/shm tmpfs defaults 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
sysfs /sys sysfs defaults 0 0
proc /proc proc defaults 0 0
UUID=8217a44e-70f1-4f84-850d-c9e8f30ae5bb /project ext4
Step 6. 掛載磁區到你要的目錄
[root@xxxxx tmp]# mount -t ext4 /dev/vdb /project
完成
[root@ICN-Beta-IXBataAll01 salt]# df -hFilesystem Size Used Avail Use% Mounted on
/dev/vda1 50G 1.3G 46G 3% /
tmpfs 3.9G 0 3.9G 0% /dev/shm
/dev/vdb 493G 70M 467G 1% /project
