企業級應用系統的建設，通常將系統和數據分別存儲，並建立raid。新裝的CentOS 6.5，需要掛載數據盤，並且能夠系統啟動自動掛載該數據盤。
1、手動掛載磁盤
查看磁盤分區信息，執行fdisk命令
[[email protected]]# 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沒有掛載，接下來建立掛載點（創建掛載目錄），執行mount命令，掛載數據盤。
[[email protected]]# mkdir /tsp
[root@tsp-rls-webservice tsp]# mount /dev/sdb1 /tsp
2、系統啟動，自動掛載數據盤
查看磁盤UUID信息
[[email protected]]# 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"
編輯系統分區表
[[email protected]]# vi /etc/fstab
添加如下信息：
UUID=e85dd659-bb20-4d12-a8bc-16130efc04ea /tsp ext4 defaults 1 2
編輯後的信息如下：
#
# /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；重啟系統，確認自動掛載成功。
