1、首先，查看磁盘，fdisk -l
Disk /dev/xvdf: 536.9 GB, 536870912000 bytes, 1048576000 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes
2、进入磁盘，对磁盘进行分区
[root@shap000103262 ~]# fdisk /dev/xvdf Welcome to fdisk (util-linux 2.23.2). Changes will remain in memory only, until you decide to write them. Be careful before using the write command. Device does not contain a recognized partition table Building a new DOS disklabel with disk identifier 0x9c0f9ab7. Command (m for help): n Partition type: p primary (0 primary, 0 extended, 4 free) e extended Select (default p): p Partition number (1-4, default 1): 1 First sector (2048-1048575999, default 2048): Using default value 2048 Last sector, +sectors or +size{K,M,G} (2048-1048575999, default 1048575999): Using default value 1048575999 Partition 1 of type Linux and of size 500 GiB is set Command (m for help): w The partition table has been altered! Calling ioctl() to re-read partition table. Syncing disks.
3、格式化分区
[root@shap000103262 ~]# mkfs.ext3 /dev/xvdf1 mke2fs 1.42.9 (28-Dec-2013) Filesystem label= OS type: Linux Block size=4096 (log=2) Fragment size=4096 (log=2) Stride=0 blocks, Stripe width=0 blocks 32768000 inodes, 131071744 blocks 6553587 blocks (5.00%) reserved for the super user First data block=0 Maximum filesystem blocks=4294967296 4000 block groups 32768 blocks per group, 32768 fragments per group 8192 inodes per group Superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208, 4096000, 7962624, 11239424, 20480000, 23887872, 71663616, 78675968, 102400000 Allocating group tables: done Writing inode tables: done Creating journal (32768 blocks): done Writing superblocks and filesystem accounting information: done
4、开始挂载分区
mount /dev/xvdf1 /opt/share
