CentOS是社区企业操作系统，是Linux发行版之一，它是来自于Red Hat Enterprise Linux依照开放源代码规定释出的源代码所编译而成。由于出自同样的源代码，因此有些要求高度稳定性的服务器以CentOS替代商业版的Red Hat Enterprise Linux使用。两者的不同，在于CentOS并不包含封闭源代码软件。
企业级应用系统的建设，通常将系统和数据分别存储，并建立raid。新装的CentOS6.5，需要挂载数据盘，并且能够系统启动自动挂载该数据盘。
1、手动挂载磁盘
查看磁盘分区信息，执行fdisk命令
[root@tsp-rls-webservice tsp]# fdisk -l
Disk /dev/sdb: 1476.5 GB, 1476529225728 bytes
255 heads, 63 sectors/track, 179511 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: 0x0008a3a1
Device Boot Start End Blocks Id System
/dev/sdb1 1 179512 1441922048 83 Linux
Disk /dev/sda: 322.1 GB, 322122547200 bytes
255 heads, 63 sectors/track, 39162 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: 0x6a5b51c5
Device Boot Start End Blocks Id System
/dev/sda1 * 1 64 512000 83 Linux
Partition 1 does not end on cylinder boundary.
/dev/sda2 64 39163 314059776 8e Linux LVM
Disk /dev/mapper/vg_tsprlswebserv-lv_root: 53.7 GB, 53687091200 bytes
255 heads, 63 sectors/track, 6527 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: 0x00000000
Disk /dev/mapper/vg_tsprlswebserv-lv_swap: 16.8 GB, 16814964736 bytes
255 heads, 63 sectors/track, 2044 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: 0x00000000
Disk /dev/mapper/vg_tsprlswebserv-lv_home: 251.1 GB, 251092008960 bytes
255 heads, 63 sectors/track, 30526 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: 0x00000000
查看到/dev/sdb1没有挂载，接下来建立挂载点(创建挂载目录)，执行mount命令，挂载数据盘。
[root@tsp-rls-webservice tsp]# mkdir /tsp
[root@tsp-rls-webservice tsp]# mount /dev/sdb1 /tsp
2、系统启动，自动挂载数据盘
查看磁盘UUID信息
[root@tsp-rls-webservice tsp]# blkid
/dev/mapper/vg_tsprlswebserv-lv_root: UUID="3dedb8a7-69c5-44d7-b590-e70a0b1b3c9a" TYPE="ext4"
/dev/sdb1: UUID="e85dd659-bb20-4d12-a8bc-16130efc04ea" TYPE="ext4"
/dev/sda1: UUID="97f12da1-c972-4508-9028-9b98cde34a34" TYPE="ext4"
/dev/sda2: UUID="cKJ1xc-8mci-0d89-DNaR-5IAG-2JOv-V1G1q9" TYPE="LVM2_member"
/dev/mapper/vg_tsprlswebserv-lv_swap: UUID="aa4589df-1d47-4060-a419-9c4432c3bb9a" TYPE="swap"
/dev/mapper/vg_tsprlswebserv-lv_home: UUID="17a62039-4676-45ce-8eb9-1914e2d4820c" TYPE="ext4"
编辑系统分区表
[root@tsp-rls-webservice tsp]# vi /etc/fstab
添加如下信息：
UUID=e85dd659-bb20-4d12-a8bc-16130efc04ea /tsp ext4 defaults 1 2
编辑后的信息如下：
#
# /etc/fstab
# Created by anaconda on Thu Aug 21 17:17:19 2014
#
# Accessible filesystems, by reference, are maintained under '/dev/disk'
# See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info
#
/dev/mapper/vg_tsprlswebserv-lv_root / ext4 defaults 1 1
UUID=97f12da1-c972-4508-9028-9b98cde34a34 /boot ext4 defaults 1 2
UUID=e85dd659-bb20-4d12-a8bc-16130efc04ea /tsp ext4 defaults 1 2
/dev/mapper/vg_tsprlswebserv-lv_home /home ext4 defaults 1 2
/dev/mapper/vg_tsprlswebserv-lv_swap swap swap defaults 0 0
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
保存退出;重启系统，确认自动挂载成功。
