首先，对新加入的硬盘格式化。
步骤1:
复制代码代码示例:
[root@rac1 ~]# 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. The number of cylinders for this disk is set to 1305. 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) 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)
步骤2:
复制代码代码示例:
Command (m for help): n
Command action e extended p primary partition (1-4) p Partition number (1-4): 1 First cylinder (1-1305, default 1): Using default value 1 Last cylinder or +size or +sizeM or +sizeK (1-1305, default 1305): Using default value 1305 Command (m for help): w The partition table has been altered! Calling ioctl() to re-read partition table. Syncing disks.
步骤3:
复制代码代码示例:
[root@rac1 ~]# fdisk -l
Disk /dev/sda: 10.7 GB, 10737418240 bytes 255 heads, 63 sectors/track, 1305 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 1147 9213246 83 Linux /dev/sda2 1148 1305 1269135 82 Linux swap Disk /dev/sdb: 10.7 GB, 10737418240 bytes 255 heads, 63 sectors/track, 1305 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sdb1 1 1305 10482381 5 Extended
步骤4 格式化分区
复制代码代码示例:
[root@rac1 ~]# mkfs -t ext3 -c /dev/sdb1
mke2fs 1.35 (28-Feb-2004) Filesystem label= OS type: Linux Block size=4096 (log=2) Fragment size=4096 (log=2) 1310720 inodes, 2620595 blocks 131029 blocks (5.00%) reserved for the super user First data block=0 Maximum filesystem blocks=2684354560 80 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, 1605632 Checking for bad blocks (read-only test): done Writing inode tables: done Creating journal (8192 blocks): done Writing superblocks and filesystem accounting information: done This filesystem will be automatically checked every 25 mounts or 180 days, whichever comes first. Use tune2fs -c or -i to override.
步骤5:创建目录然后将该分区加挂到该目录下
复制代码代码示例:
[root@rac1 /]# mkdir /u01
[root@rac1 /]# mount /dev/sdb1 /u01
说明:
复制代码代码示例:
mkfs -t ext3 -c /dev/sdb1
Invalid argument passed to ext2 library while setting up superblock.
复制代码代码示例:
[root@jbxue oracle]# fdisk /dev/sdb
The number of cylinders for this disk is set to 2088. 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) 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) Command (m for help): n Command action l logical (5 or over) p primary partition (1-4) l First cylinder (1-2088, default 1): Using default value 1 Last cylinder or +size or +sizeM or +sizeK (1-2088, default 2088): Using default value 2088 Command (m for help): w The partition table has been altered! Calling ioctl() to re-read partition table. Syncing disks. [root@jbxue oracle]# 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 1000 8032468+ 83 Linux /dev/sda2 1001 1200 1606500 82 Linux swap / Solaris /dev/sda3 1201 2610 11325825 83 Linux Disk /dev/sdb: 17.1 GB, 17179869184 bytes 255 heads, 63 sectors/track, 2088 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sdb1 1 2088 16771828+ 5 Extended /dev/sdb5 1 2088 16771797 83 Linux [root@jbxue oracle]# mkfs -t ext3 -c /dev/sdb5 mke2fs 1.39 (29-May-2006) Filesystem label= OS type: Linux Block size=4096 (log=2) Fragment size=4096 (log=2) 2097152 inodes, 4192949 blocks 209647 blocks (5.00%) reserved for the super user First data block=0 Maximum filesystem blocks=0 128 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, 1605632, 2654208, 4096000 Checking for bad blocks (read-only test): done Writing inode tables: done Creating journal (32768 blocks): done Writing superblocks and filesystem accounting information: done This filesystem will be automatically checked every 21 mounts or 180 days, whichever comes first. Use tune2fs -c or -i to override. [root@jbxue oracle]# 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 1000 8032468+ 83 Linux /dev/sda2 1001 1200 1606500 82 Linux swap / Solaris /dev/sda3 1201 2610 11325825 83 Linux Disk /dev/sdb: 17.1 GB, 17179869184 bytes 255 heads, 63 sectors/track, 2088 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sdb1 1 2088 16771828+ 5 Extended /dev/sdb5 1 2088 16771797 83 Linux 如此便完成了linux下新硬盘的添加与分区、格式化等操作。 (责任编辑：IT) |
