linux 创建新分区,重启后挂载有效.

第一步：创建分区
root# fdisk /dev/had à进入到新添加的硬盘中

The number of cylinders for this disk is set to 10402. 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) Command (m for help): n à创建新分区 Command action e extended p primary partition (1-4) p à创建主分区 Partition number (1-4): 1 à新建的主分区序号 First cylinder (1-10402, default 1): Using default value 1 Last cylinder or +size or +sizeM or +sizeK (1-10402, default 10402): +500M à创建主分区大小 Command (m for help): w à保存创建的主分区

第二步：使新创建的分区在系统中立即生效

root#partprobe

第三步：格式化新创建的分区

[root@server ~]# mkfs.ext3 /dev/hda1 mke2fs 1.39 (29-May-2006) Filesystem label= OS type: Linux Block size=1024 (log=0) Fragment size=1024 (log=0) 122400 inodes, 488848 blocks 24442 blocks (5.00%) reserved for the super user First data block=1 Maximum filesystem blocks=67633152 60 block groups 8192 blocks per group, 8192 fragments per group 2040 inodes per group Superblock backups stored on blocks: 8193, 24577, 40961, 57345, 73729, 204801, 221185, 401409 Writing inode tables: done Creating journal (8192 blocks): done Writing superblocks and filesystem accounting information: done This filesystem will be automatically checked every 27 mounts or 180 days, whichever comes first. Use tune2fs -c or -i to override. [root@server ~]#

第四步：使新创建的分区挂载/mnt/rhce01 目录下

Root#mount /dev/hda1 /mnt/rhce01

第五步：让挂载在系统重启后仍然有效

root# vim /etc/fstab à编辑这个文件，添加上下面的一行，使挂载在重启后有效； LABEL=/1 / ext3 defaults 1 1 tmpfs /dev/shm tmpfs defaults 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 sysfs /sys sysfs defaults 0 0 proc /proc proc defaults 0 0 LABEL=SWAP-sda3 swap swap defaults 0 0 /dev/hda1 /mnt/rhce01 ext3 defaults 0 0
