Linux磁盘挂载操作手册 一、挂载单个分区小于2T的分区 1.查看系统当前分区情况 命令df –h 实例： Last login: Fri Oct 26 00:01:51 2012 from e10-3 E10-3:~ # df -h Filesystem Size Used Avail Use% Mounted on /dev/sda2 40G 4.7G 33G 13% / devtmpfs 12G 144K 12G 1% /dev tmpfs 3.9G 100K 3.9G 1% /dev/shm /dev/sda1 479M 72M 383M 16% /boot /dev/sda5 869G 201M 824G 1% /home /dev/sr0 2.9G 2.9G 0 100% /media/SLES-11-SP1-DVD-x86_64.0432..001 2.查看系统当前硬盘分区情况 命令：fdisk –l E10-3:~ # fdisk -l Disk /dev/sda: 999.0 GB, 998999326720 bytes 255 heads, 63 sectors/track, 121454 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00004cb7 Device Boot Start End Blocks Id System /dev/sda1 * 1 63 506016 83 Linux /dev/sda2 64 5284 83 Linux /dev/sda3 5285 6328 8385930 82 Linux swap / Solaris /dev/sda4 6329 121454 924749595 f W95 Extd (LBA) /dev/sda5 6329 121452 924733498+ 83 Linux Disk /dev/sdb: 999.0 GB, 998999326720 bytes 255 heads, 63 sectors/track, 121454 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0Disk /dev/sdb doesnt contain a valid partition table Disk /dev/sdc: 4994.0 GB, 4993981612032 bytes 255 heads, 63 sectors/track, 607150 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0Disk /dev/sdc doesnt contain a valid partition table 3.创建新的硬盘分区 命令： fdisk /dev/sdb 注：这里的/dev/sdb是具体一个硬盘，此参数可改成fdisk –l显示的硬盘的序号。 实例： E10-3:~ # fdisk /dev/sdb Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel Building a new DOS disklabel with disk identifier 0xd3f0a6aa. Changes will remain in memory only, until you decide to write them. After that, of course, the previous content wont be recoverable. The number of cylinders for this disk is set to 1214
