在购买VPS之后,要手动将另外一块硬盘激活,于是乎,就有了这个如何启用分区的教程:通过fdisk -l我们可以看到/dev/xvdb(此名称因系统而异)容量有23.6G，而且没有分区，接下来我们对它进行分区和挂载fdisk -l[root@MyVPS ~]# fdisk -lDisk /dev/xvda: 8589 MB, 8589934592 bytes255 heads, 63 sectors/track, 1044 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System/dev/xvda1 * 1 13 104391 83 Linux/dev/xvda2 14 1044 8281507+ 8e Linux LVMDisk /dev/xvdb: 23.6 GB, 23622320128 bytes255 heads, 63 sectors/track, 2871 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytesDevice Boot Start End Blocks Id System对/dev/xvdb(此名称因系统而异)进行分区：fdisk /dev/xvdb[root@MyVPS ~]# fdisk /dev/xvdbThe number of cylinders for this disk is set to 2871.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)输入n新建分区Command (m for help): nCommand action e extended p primary partition (1-4)p/dev/xvdb中第1个分区Partition number (1-4): 1First cylinder (1-2871, default 1):Using default value 1Last cylinder or +size or +sizeM or +sizeK (1-2871, default 2871):Using default value 2871输入W保存退出Command (m for help): wThe partition table has been altered!Calling ioctl() to re-read partition table.Syncing disks.将新分区xvdb1(此名称因系统而异)格式化为ext3格式[root@MyVPS ~]# mkfs -t ext3 /dev/xvdb1mke2fs 1.39 (29-May-2006)Filesystem label=OS type: LinuxBlock size=4096 (log=2)Fragment size=4096 (log=2)2883584 inodes, 5765319 blocks288265 blocks (5.00%) reserved for the super userFirst data block=0Maximum filesystem blocks=4294967296176 block groups32768 blocks per group, 32768 fragments per group16384 inodes per groupSuperblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208, 4096000Writing inode tables: doneCreating journal (32768 blocks): doneWriting superblocks and filesystem accounting information: doneThis filesystem will be automatically checked every 24 mounts or180 days, whichever comes first. Use tune2fs -c or -i to override.我们示范将新分区xvdb1挂载到目录/home因为home已经存在，所以我们挂载mount /dev/xvdb1 /home如果你需要挂载在别的目录.可以新建一个目录挂载.如:home1,使用如下命令:mkdir /home1mount /dev/xvdb1 /home1完成后我们通过df -hal可以看到，新分区已经挂载到目录/home上了[root@MyVPS ~]# df -halFilesystem Size Used Avail Use% Mounted on/dev/mapper/VolGroup00-LogVol00 5.7G 1.4G 4.1G 25% /proc 0 0 0 - /procsysfs 0 0 0 - /sysdevpts 0 0 0 - /dev/pts/dev/xvda1 99M 28M 67M 30% /boottmpfs 256M 0 256M 0% /dev/shmnone 0 0 0 - /proc/sys/fs/binfmt_miscsunrpc 0 0 0 - /var/lib/nfs/rpc_pipefs/dev/xvdb1 22G 173M 21G 1% /home最后添加开机自动挂载：echo "/dev/xvdb1 /home ext3 defaults 1 2" >> /etc/fstab这样就完成了！通过后台控制系统重做系统之后,只需要重新挂载一次即可mount /dev/xvdb1 /home最后，重新添加自动挂载即可：echo "/dev/xvdb1 /home ext3 defaults 1 2" >> /etc/fstab
