1.查看要挂载的空间

2.添加分区
1 [[email protected] ~]# fdisk /dev/vdb
2 Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
3 Building a new DOS disklabel with disk identifier 0x65cce73f.
4 Changes will remain in memory only, until you decide to write them.
5 After that, of course, the previous content won‘t be recoverable.

11 sectors (command ‘u‘).

3.查看当前分区情况
1 [[email protected] ~]# fdisk -l 2 3 Disk /dev/vda: 42.9 GB, 42949672960 bytes 4 255 heads, 63 sectors/track, 5221 cylinders 5 Units = cylinders of 16065 * 512 = 8225280 bytes 6 Sector size (logical/physical): 512 bytes / 512 bytes 7 I/O size (minimum/optimal): 512 bytes / 512 bytes 8 Disk identifier: 0x00053156 9 10 Device Boot Start End Blocks Id System 11 /dev/vda1 * 1 5222 41942016 83 Linux 12 13 Disk /dev/vdb: 107.4 GB, 107374182400 bytes 14 16 heads, 63 sectors/track, 208050 cylinders 15 Units = cylinders of 1008 * 512 = 516096 bytes 16 Sector size (logical/physical): 512 bytes / 512 bytes 17 I/O size (minimum/optimal): 512 bytes / 512 bytes 18 Disk identifier: 0x65cce73f 19 20 Device Boot Start End Blocks Id System 21 /dev/vdb1 1 208050 104857168+ 83 Linux
4.格式化分区

Use tune2fs -c or -i to override.
5.挂载硬盘
1 #创建要挂载的目录 2 mkdir /data 3 4 #挂载分区 5 mount /dev/vdb1 /data/ 6 7 #写入分区信息 8 echo "/dev/vdb1 /data ext3 defaults 0 0" >> /etc/fstab 9 10 #查看分许信息 11 cat /etc/fstab
