1、对第一块盘/dev/sdb进行分区：
[root@rac1 ~]# fdisk /dev/sdb Device contains neither a valid DOS partition table,nor Sun,sgi or OSF disklabel Building a new DOS disklabel with disk identifier 0x06b87c6d. 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) WARNING: DOS-compatible mode is deprecated. It's strongly recommended to switch off the mode (command 'c') and change display units to sectors (command 'u'). Command (m for help): n Command action e extended p primary partition (1-4) p Partition number (1-4): 1 First cylinder (1-1566,default 1): Using default value 1 Last cylinder,+cylinders or +size{K,M,G} (1-1566,default 1566): Using default value 1566 Command (m for help): p disk /dev/sdb: 12.9 GB,12884901888 bytes 255 heads,63 sectors/track,1566 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: 0x06b87c6d Device Boot Start End Blocks Id System /dev/sdb1 1 1566 12578863+ 83 Linux Command (m for help): w The partition table has been altered! Calling ioctl() to re-read partition table. Syncing disks.
2、查看分区是否正常
[root@rac1 ~]# fdisk -l /dev/sdb disk /dev/sdb: 12.9 GB,1566 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: 0x06b87c6d Device Boot Start End Blocks Id System /dev/sdb1 1 1566 12578863+ 83 Linux
3、ok，分区正常。按照上述方法，把剩下的六块盘都分区。
