Linux VPS新硬盘分区与挂载教程
??? 这里有两个选项：?
??? p: 主分区 linux上主分区最多能有4个?
??? e: 扩展分区 linux上扩展分区只能有1个，扩展分区创建后不能直接使用，还要在扩展分区上创建逻辑分区。?
这里我选择的p。
--------------------------------------------------
/dev/xvdb中第1个分区
--------------------------------------------------
选择分区个数?
可以选择4个分区，这里我只分成1个分区?
--------------------------------------------------
Partition number (1-4):?1
First cylinder (1-2871, default 1):
Using default value 1
Last cylinder or +size or +sizeM or +sizeK (1-2871, default 2871):
Using default value 2871
输入W保存退出
Command (m for help):?w
The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.
通过上述步骤我们已将/dev/xvdb分区完成，下面我们对分区格式化并进行挂载
将新分区xvdb1(此名称因系统而异)格式化为ext3格式
?
# mkfs -t ext3 /dev/xvdb1
[root@MyVPS ~]#?mkfs -t ext3 /dev/xvdb1
mke2fs 1.39 (29-May-2006)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
2883584 inodes, 5765319 blocks
288265 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=4294967296
176 block groups
32768 blocks per group, 32768 fragments per group
16384 inodes per group
Superblock backups stored on blocks:
32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208,
4096000
Writing inode tables: done
Creating journal (32768 blocks): done
Writing superblocks and filesystem accounting information: done
This filesystem will be automatically checked every 24 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.
将新分区xvdb1挂载，我们示例挂载到/www目录。新建目录/www，然后挂载：
# mkdir /www?? /*建立www目录*/
# mount /dev/xvdb1 /www??? /*挂载到www目录*/
完成后我们通过df -hal可以看到，新分区已经挂载到目录/www上了
?
[root@MyVPS ~]#?df -hal
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
5.7G 1.4G 4.1G 25% /
proc 0 0 0 - /proc
sysfs 0 0 0 - /sys
devpts 0 0 0 - /dev/pts
/dev/xvda1 99M 28M 67M 30% /boot
tmpfs 256M 0 256M 0% /dev/shm

sunrpc 0 0 0 - /var/lib/nfs/rpc_pipefs
/dev/xvdb1 22G 173M 21G 1% /www
然后编辑/etc/fstab使分区在开机时自动挂载到www
# echo "/dev/xvdb1 /www ext3 defaults 1 2" >> /etc/fstab
