1.使用fdisk 查看硬盘信息
[root@localhost ~]# fdisk -l Disk /dev/sdb: 107.4 GB, 107374182400 bytes 255 heads, 63 sectors/track, 13054 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/sda: 161.1 GB, 161061273600 bytes 255 heads, 63 sectors/track, 19581 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: 0x0000955d Device Boot Start End Blocks Id System /dev/sda1 * 1 64 512000 83 Linux Partition 1 does not end on cylinder boundary. /dev/sda2 64 325 2097152 82 Linux swap / Solaris Partition 2 does not end on cylinder boundary. /dev/sda3 325 19582 154676224 83 Linux [root@localhost ~]#
2.格式化硬盘、挂载硬盘、卸载挂载
mkfs -t ext4 /dev/sda //格式化硬盘 mkdir data //创建挂载目录 #mount 硬盘地址 要挂载的地址、需指定文件目录 #mount /dev/sdb /data //挂载 #df -h //查看是否挂载 #umount /dev/sdb //卸载硬盘挂载
3.配置开机自动挂载
//因为mount挂载在重启服务器后会失效，所以需要将分区信息写到/etc/fstab文件中让它永久挂载： [root@oracle /]# vim /etc/fstab 加入： /dev/sdb1(磁盘分区) /data1（挂载目录） ext3（文件格式）defaults 0 0
