1.查看要挂载的空间

1 [root@iZuf6610s5jsqm9fr53nslZ ~]# 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  System11 /dev/vda1   *           1        5222    41942016   83  Linux12 13 Disk /dev/vdb: 107.4 GB, 107374182400 bytes14 16 heads, 63 sectors/track, 208050 cylinders15 Units = cylinders of 1008 * 512 = 516096 bytes16 Sector size (logical/physical): 512 bytes / 512 bytes17 I/O size (minimum/optimal): 512 bytes / 512 bytes18 Disk identifier: 0x00000000

 

2.添加分区

3.查看当前分区情况

1 [root@iZuf6610s5jsqm9fr53nslZ ~]# 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  System11 /dev/vda1   *           1        5222    41942016   83  Linux12 13 Disk /dev/vdb: 107.4 GB, 107374182400 bytes14 16 heads, 63 sectors/track, 208050 cylinders15 Units = cylinders of 1008 * 512 = 516096 bytes16 Sector size (logical/physical): 512 bytes / 512 bytes17 I/O size (minimum/optimal): 512 bytes / 512 bytes18 Disk identifier: 0x65cce73f19 20    Device Boot      Start         End      Blocks   Id  System21 /dev/vdb1               1      208050   104857168+  83  Linux

 

4.格式化分区

1 [root@iZuf6610s5jsqm9fr53nslZ ~]# mkfs.ext3 /dev/vdb1  2 mke2fs 1.41.12 (17-May-2010) 3 Filesystem label= 4 OS type: Linux 5 Block size=4096 (log=2) 6 Fragment size=4096 (log=2) 7 Stride=0 blocks, Stripe width=0 blocks 8 6553600 inodes, 26214292 blocks 9 1310714 blocks (5.00%) reserved for the super user10 First data block=011 Maximum filesystem blocks=429496729612 800 block groups13 32768 blocks per group, 32768 fragments per group14 8192 inodes per group15 Superblock backups stored on blocks: 16     32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208, 17     4096000, 7962624, 11239424, 20480000, 2388787218 19 Writing inode tables: done                            20 Creating journal (32768 blocks): done21 Writing superblocks and filesystem accounting information: done22 23 This filesystem will be automatically checked every 31 mounts or24 180 days, whichever comes first.

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
