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 -lDisk /dev/sdb: 1476.5 GB, 1476529225728 bytes255 heads, 63 sectors/track, 179511 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk identifier: 0x0008a3a1 Device Boot Start End Blocks Id System/dev/sdb1 1 179512 1441922048 83 LinuxDisk /dev/sda: 322.1 GB, 322122547200 bytes255 heads, 63 sectors/track, 39162 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk identifier: 0x6a5b51c5 Device Boot Start End Blocks Id System/dev/sda1 * 1 64 512000 83 LinuxPartition 1 does not end on cylinder boundary./dev/sda2 64 39163 314059776 8e Linux LVMDisk /dev/mapper/vg_tsprlswebserv-lv_root: 53.7 GB, 53687091200 bytes255 heads, 63 sectors/track, 6527 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk identifier: 0x00000000Disk /dev/mapper/vg_tsprlswebserv-lv_swap: 16.8 GB, 16814964736 bytes255 heads, 63 sectors/track, 2044 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk identifier: 0x00000000Disk /dev/mapper/vg_tsprlswebserv-lv_home: 251.1 GB, 251092008960 bytes255 heads, 63 sectors/track, 30526 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk 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 1UUID=97f12da1-c972-4508-9028-9b98cde34a34 /boot ext4 defaults 1 2UUID=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 0tmpfs /dev/shm tmpfs defaults 0 0devpts /dev/pts devpts gid=5,mode=620 0 0sysfs /sys sysfs defaults 0 0proc /proc proc defaults 0 0 保存退出；重启系统，确认自动挂载成功。
