linux挂载新硬盘分区

linux挂载新硬盘分区 linux 挂载新硬载 fdisk / parted 分载, 磁载存载 linux载新硬载命令, 挂fdisk;2T硬载以下, / parted;2T硬载以上, Linux的硬载载载: 一般使用”fdisk -l”命令可以列出系载中前载接的硬载当 载载和分信息区.新硬载有分信息没区,载只载示硬载大小信息. 1.载载服载器加上新硬载 2.载服载器～以启root用载登载 3.载看硬载信息 #fdisk -l Disk /dev/sda: 42.9 GB, 42949672960 bytes 255 heads, 63 sectors/track, 5221 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk identifier: 0x0004406e Device Boot Start End Blocks Id System/dev/sda1 * 1 39 307200 83 LinuxPartition 1 does not end on cylinder boundary. /dev/sda2 39 2589 20480000 83 Linux/dev/sda3 2589 2850 2097152 82 Linux swap / Solaris /dev/sda4 2850 5222 19057664 5 Extended/dev/sda5 2850 5222 19056640 83 LinuxDisk /dev/sdb: 10.7 GB, 10737418240 bytes 255 heads, 63 sectors/track, 1305 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk identifier: 0x14b52796 Device Boot Start End Blocks Id System4.载建新硬载分命令,区参数 fdisk可以用m命令看来fdisk命令的部命令～内 a,命令指定载分～启区 d,命令载除一存在的分～个区 l,命令载示分区ID的列～号 m,载看fdisk命令助～帮 n,命令载建一新分～个区 p,命令载示分列表～区 t,命令修改分的载型区ID～号 w,命令是载分表的修改存载载载生作用。将区它 5.载入磁载～载磁载载行分～区注意载色部分。 #fdisk /dev/sdb Command (m for help):n Command action 　　 e extended //载入e载载建载展分区 　　 p primary partition (1-4) //载入p载载建载载分区 p Partion number(1-4),1 //在载里载入l～就载入分载载分载段了～划区 First cylinder (51-125, default 51): //注,载就是分的个区Start 载～载里最好直接按回载～如果载入了一非默载的字～造成空载浪载～您个数会 Using default value 51 Last cylinder or +size or +sizeM or +sizeK (51-125, default 125): +200M 注,载是定载分大小的～个区+200M 就是大小载200M ～然也可以根据当您p提示的载位cylinder的大小算～然后指定 来来End的载。回载看看是载算的～载是用数怎 +200M载载法添加～载载能直载一点。如果想添加一个来您个10G左右大小的分区～载载入 +10000M ～ Command (m for help): w //最后载入w回载保存。载看一下, #fdisk -l 可以看到/dev/sdb1分区,我就省略截载。咯 6.化分,区 #mkfs.ext3 /dev/sdb1 //注,将/dev/sdb1格式化载ext3载型mke2fs 1.41.12 (17-May-2010) 文件系载载载= 操作系载:Linux 载大小=4096 (log=2) 分载大小=4096 (log=2) Stride=0 blocks, Stripe width=0 blocks640848 inodes, 2562359 blocks 128117 blocks (5.00%) reserved for the super user 第一据载个数=0 Maximum filesystem blocks=262563430479 block groups 32768 blocks per group, 32768 fragments per group 8112 inodes per group Superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632 正在入写inode表: 完成 Creating journal (32768 blocks): 完成Writing superblocks and filesystem accounting information: 完成 This filesystem will be automatically checked every 35 mounts or180 days, whichever comes first. Use tune2fs -c or -i to override.载载就格式化好了～我载就可以用mount 加载载分～然后使用载文件系载～个区个 7.载建/data1目载, #mkdir /data1 8.载始载分,挂区 #mount /dev/sdb1 /data1 9.载看硬载大小以及载分,挂区 #dh -h 10.配置载机自载载挂 因载mount载在重服载器后失效～所以需要分信息到挂启会将区写/etc/fstab文件中 载永久载,它挂 #vim /etc/fstab 加入, /dev/sdb1(磁载分区) /data1;载目载, 挂ext3;文件格式,defaults 0 0 11.重系载启 ################################# 当超载2T的硬载不可以用fdisk载行分～必载得用来区parted.
