1.先看看情况 [root@localhost tmp]# fdisk -l
Disk /dev/sda: 3221 MB, 3221225472 bytes 255 heads, 63 sectors/track, 391 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System /dev/sda1 * 1 261 2096451 83 Linux /dev/sda2 262 391 1044225 82 Linux swap 看到我原先给linux分了两个区,一个是linux(2G),一个是linux swap(竟然有1G) 这个swap的空间那么大呢,可是好像用不上,那就只能从它开刀了。得修改分区表。
2.分区工具parted [root@localhost tmp]# parted 然后就进入parted的命令环境了
(parted) print --打印当前分区信息 Disk geometry for /dev/sda: 0.000-3072.000 megabytes Disk label type: msdos Minor Start End Type Filesystem Flags 1 0.031 2047.346 primary ext3 boot 2 2047.346 3067.097 primary linux-swap
根据帮助的指示,觉得resize命令可能就是我要找的,先把分区2变小 (parted) resize 2 3000 3067.097
执行完了,再看看结果如何 (parted) print Disk geometry for /dev/sda: 0.000-3072.000 megabytes Disk label type: msdos Minor Start End Type Filesystem Flags 1 0.031 2047.346 primary ext3 boot 2 2996.499 3067.097 primary linux-swap
果然改变了,那么把分区1变大吧 (parted) resize 1 0.031 2996.499 Warning: Filesystem was not cleanly unmounted! You should e2fsck. Ignore/Cancel? c 好像这么弄不行,那就算了,另想个办法, 把空出的空间单独作为一个分区吧 (parted) mkpartfs primary ext2 2047.346 2996.499 (parted) print Disk geometry for /dev/sda: 0.000-3072.000 megabytes Disk label type: msdos Minor Start End Type Filesystem Flags 1 0.031 2047.346 primary ext3 boot 3 2047.346 2996.499 primary ext2 2 2996.499 3067.097 primary linux-swap 这个方法奏效了 退出再看看 [root@localhost tmp]# fdisk -l
Disk /dev/sda: 3221 MB, 3221225472 bytes 255 heads, 63 sectors/track, 391 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System /dev/sda1 * 1 261 2096451 83 Linux /dev/sda2 383 391 72292+ 82 Linux swap /dev/sda3 262 382 971932+ 83 Linux
3、对分区进行格式化,以及加载;
先提示一下;用 mkfs.bfs mkfs.ext2 mkfs.jfs mkfs.msdos mkfs.vfatmkfs.cramfs mkfs.ext3 mkfs.minix mkfs.reiserfs mkfs.xfs 等命令来格式化分区,比如我想格式化 sda3为ext3文件系统,则输入;
[root@localhost tmp]# mkfs.ext3 /dev/sda3
如果我想加载 sda3到目前系统来存取文件,应该有mount 命令,但首先您得建一个挂载目录;比如 /mnt/sda3 ;
[root@localhost tmp]# mkdir /mnt/sda3 [root@localhost tmp]# mount /dev/sda3 /mnt/sda3
