1、公司内网的服务器硬盘空间不足，将新买来的150G硬盘挂载并设置成samba的共享目录，关于samba请参考此文章http:/ 1、# fdisk -l 查看当前磁盘信息，就会发现最下面显示新加入的硬盘不是有效分区，如下：Disk /dev/sdc: 1500.3 GB, 1500301910016 bytes255 heads, 63 sectors/track, 182401 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytesDisk /dev/sdc doesnt contain a valid partition table
2、2、# fdisk /dev/sdc 对新硬盘分区，并根据提示进一步操作Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabelBuilding a new DOS disklabel. Changes will remain in memory only,until you decide to write them. After that, of course, the previouscontent wont be recoverable.The number of cylinder
3、s for this disk is set to 182401.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: inv
4、alid flag 0x0000 of partition table 4 will be corrected by w(rite)Command (m for help): h 输入h可查看帮助命令h: unknown commandCommand 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 parti

6、and (m for help): n 输入n进行分区Command action e extended p primary partition (1-4)p 输入p为主分区，e为逻辑分区Partition number (1-4): 1 由于是新盘我们输入1来分第一个主分区，共可以分4个主分区First cylinder (1-182401, default 1): 选择该分区的起始磁盘数，如无特殊需求强烈建议选择默认，也就是1来分区（直接按回车）Using default value 1Last cylinder or +size or +sizeM or +sizeK (1-182401
7、, default 182401): 定义该分区的大小，如果按默认（按回车）即是使用全部可用存储额，如分一个1G的空间，输入+1024mUsing default value 182401Command (m for help): w 写入分区The partition table has been altered!Calling ioctl() to re-read partition table.Syncing disks.3、# fdisk -l 可以找到我们刚才分的一个分区，内容如下：Disk /dev/sdc: 1500.3 GB, 1500301910016 bytes255 he

11、erblocks and filesystem accounting information: doneThis filesystem will be automatically checked every 22 mounts or180 days, whichever comes first. Use tune2fs -c or -i to override.5、# mkdir /var/samba 新建挂载目录6、# mount /dev/sdc1 /var/samba 挂载新硬盘7、# df -hl 查看分区大小是否和我们预定的一样：文件系统 容量 已用 可用 已用% 挂载点/dev/s
