在Linux操作系统下增加新硬盘的方法
在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)
