1、在虚拟机中添加一块磁盘 2、在root用户下fdisk -l查看磁盘情况并且找到新添加的未挂载的硬盘 3、格式化添加到分区 [root@bogon ~]# fdisk /dev/sdb Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel Building a new DOS disklabel. Changes will remain in memory only, until you decide to write them. After that, of course, the previous content won't be recoverable.
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
Command (m for help): m Command 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 partition o create a new empty DOS partition table p print the partition table q quit without saving changes s create a new empty Sun disklabel t change a partition's system id u change display/entry units v verify the partition table w write table to disk and exit x extra functionality (experts only)

Calling ioctl() to re-read partition table. Syncing disks.
4、查看添加到分区以后的新名称 [root@bogon ~]# fdisk -l
Disk /dev/sda: 21.4 GB, 21474836480 bytes 255 heads, 63 sectors/track, 2610 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System /dev/sda1 * 1 13 104391 83 Linux /dev/sda2 14 274 2096482+ 82 Linux swap / Solaris /dev/sda3 275 2610 18763920 83 Linux
Disk /dev/sdb: 5368 MB, 5368709120 bytes 255 heads, 63 sectors/track, 652 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System /dev/sdb1 1 652 5237158+ 83 Linux
5、创建文件系统,为磁盘创建格式: [root@bogon ~]# mkfs.ext3 /dev/sdb1 mke2fs 1.39 (29-May-2006) Filesystem label= OS type: Linux Block size=4096 (log=2) Fragment size=4096 (log=2) 655360 inodes, 1309289 blocks 65464 blocks (5.00%) reserved for the super user First data block=0 Maximum filesystem blocks=1342177280 40 block groups 32768 blocks per group, 32768 fragments per group 16384 inodes per group Superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736
Writing inode tables: done Creating journal (32768 blocks): done Writing superblocks and filesystem accounting information: done
This filesystem will be automatically checked every 22 mounts or 180 days, whichever comes first. Use tune2fs -c or -i to override.
6、创建存储数据文件并执行挂载 [root@bogon ~]# mkdir /oradata [root@bogon ~]# mount /dev/sdb1 /oradata
7、给oradata赋权限 [root@bogon ~]# chown -R oracle:oinstall /oradata
8、oracle用户下在oradata下面以实例名创建目录 [oracle@bogon ~]$ cd /oradata [oracle@bogon oradata]$ mkdir orcl [oracle@bogon oradata]$ ls orcl |
