1，先使用fdisk进行磁盘分区，一般直接分成一个区
[root@crm_db_m01 ~]# fdisk /dev/sdc
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0xd788cc0a.
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): n
Command action
e extended
p primary partition (1-4)
p
Partition number (1-4): 1
First cylinder (1-133544, default 1):
Using default value 1
Last cylinder, +cylinders or +size{K,M,G} (1-133544, default 133544):
Using default value 133544
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): w
The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.

2，分区后查看实际分好的分区磁盘目录名称
[root@crm_db_m01 ~]# fdisk -l
Disk /dev/sda: 32.2 GB, 32212254720 bytes
255 heads, 63 sectors/track, 3916 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x000c23d3
Device Boot Start End Blocks Id System
/dev/sda1 * 1 3789 30432256 83 Linux
/dev/sda2 3789 3917 1024000 82 Linux swap / Solaris
Disk /dev/sdb: 240.5 GB, 240518168576 bytes

/dev/sdc1 1 133544 1072692148+ 83 Linux
4，开始挂载新的分区磁盘到/oracle
[root@crm_db_m01 ~]# mkdir /oracle
[root@crm_db_m01 ~]# mount /dev/sdc1 /oracle
[root@crm_db_m01 ~]#
5，开机启动挂载配置
需要用uuid的方式挂载，最好先用ulkid获取/dev/sdc1的uuid，然后再设置开机启动挂载配置
[root@crm_db_m01 ~]# blkid
/dev/sda1: UUID="6d089360-3e14-401d-91d0-378f3fd09332" TYPE="ext4"
/dev/sdc1: UUID="81796489-70bd-4707-b844-9088f8a1a209" TYPE="ext4"
[root@crm_db_m01 ~]#
进行配置/etc/fstab，配置uuid
[root@crm_db_m01 ~]# vim /etc/fstab
You have new mail in /var/spool/mail/root
[root@crm_db_m01 ~]# more /etc/fstab
#
