CentOS6.5开机自动挂载硬盘

    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 /dev/sda: 322.1 GB, 322122547200 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

Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes

Disk /dev/mapper/vg_tsprlswebserv-lv_swap: 16.8 GB, 16814964736 bytes

Units = cylinders of 16065 * 512 = 8225280 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

#
# Accessible filesystems, by reference, are maintained under '/dev/disk'

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。
