随着计算机技术的发展，计算机硬盘的价格已经很低，可能许多朋友手里都有两块硬盘，那么我们如何将第二块硬盘也应用在Linux操作系统之上呢，下面就给大家介绍一下在LINUX系统上增加硬盘操作办法: [root@gyhredhat root]# fdisk Usage: fdisk [-l] [-b SSZ] [-u] device E.g.: fdisk /dev/hda (for the first IDE disk) or: fdisk /dev/sdc (for the third SCSI disk) or: fdisk /dev/eda (for the first PS/2 ESDI drive) or: fdisk /dev/rd/c0d0 or: fdisk /dev/ida/c0d0 (for RAID devices) ... [root@gyhredhat root]# df -k 文件系统 1K-块 已用 可用 已用% 挂载点 /dev/sda3 3723848 705968 2828716 20% / /dev/sda1 101089 9274 86596 10% /boot none 14520 0 14520 0% /dev/shm 对新硬盘分区，4G硬盘中划出1G作为新分区。给/home使用 [root@gyhredhat root]# fdisk /dev/hda Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel Building a new DOS disklabel. Changes will remain in memory only, until you decide to write them. After that, of course, the previous content won't be recoverable. The number of cylinders for this disk is set to 8322. There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with: 1) software that runs at boot time (e.g., old versions of LILO) 2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK) Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite) Command (m for help): p Disk /dev/hda: 4294 MB, 4294967296 bytes 16 heads, 63 sectors/track, 8322 cylinders Units = cylinders of 1008 * 512 = 516096 bytes Device Boot Start End Blocks Id System Command (m for help): m Command action a toggle a bootable flag b edit bsd disklabel c toggle the dos compatibility flag d delete a partition l list known partition types m print this menu n add a new partition o create a new empty DOS partition table p print the partition table q quit without saving changes s create a new empty Sun disklabel t change a partition's system id u change display/entry units v verify the partition table w write table to disk and exit x extra functionality (experts only) Command (m for help): n Command action e extended p primary partition (1-4) p Partition number (1-4): 1 First cylinder (1-8322, default 1): Using default value 1 Last cylinder or +size or +sizeM or +sizeK (1-8322, default 8322): 1000G Command (m for help): p Disk /dev/hda: 4294 MB, 4294967296 bytes 16 heads, 63 sectors/track, 8322 cylinders Units = cylinders of 1008 * 512 = 516096 bytes Device Boot Start End Blocks Id System /dev/hda1 1 1000 503968+ 83 Linux Command (m for help): w The partition table has been altered!
