| Command (m for help): n Command action e extended ···扩展分区 p primary partition (1-4) ···主分区 p Partition number (1-4): 1 First cylinder (1-2610, default 1): Using default value 1 Last cylinder, +cylinders or +size{K,M,G} (1-2610, default 2610): Using default value 2610 |
4、输入p查看分区情况——输入w保存退出（一定要w保存不然无效）
| Command (m for help): p Disk /dev/sdb: 21.5 GB, 21474836480 bytes 255 heads, 63 sectors/track, 2610 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x09f38795 Device Boot Start End Blocks Id System /dev/sdb1 1 2610 20964793+ 83 Linux Command (m for help): w The partition table has been altered! Calling ioctl() to re-read partition table. Syncing disks. |
5、mkfs命令格式化磁盘
| [root@oracle ~]# mkfs.ext4 /dev/sdb mkfs.ext4: invalid fragment size - /dev/sdb |
6、mount命令挂载分区
| [root@oracle ~]# mount /dev/sdb /oracle/ You have new mail in /var/spool/mail/root [root@oracle ~]# df -TH Filesystem Type Size Used Avail Use% Mounted on /dev/sda2 ext4 19G 11G 7.3G 60% / tmpfs tmpfs 2.1G 74k 2.1G 1% /dev/shm /dev/sda1 ext4 297M 29M 253M 11% /boot /dev/sdb ext4 22G 47M 20G 1% /oracle |
7、添加到/etc/fstab文件下保存退出否则重启后硬盘消失
| /dev/sdb /oracle ext4 defaults,noatime 0 0 |
