[root@db1 /]# 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 * 151 1305 9277537+ 83 Linux /dev/sda2 1 150 1204843+ 82 Linux swap Partition table entries are not in disk order 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 从查询结果看出,多了一个/dev/sdb的盘.
2.用fdisk 对/dev/sdb 进行分区,代码如下:
[root@db1 /]# fdisk /dev/sdb Command (m for help): n Command action e extended p primary partition (1-4) p Partition number (1-4): 1 First cylinder (1-652, default 1): Using default value 1 Last cylinder or +size or +sizeM or +sizeK (1-652, default 652): Using default value 652
Command (m for help): w The partition table has been altered!
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 * 151 1305 9277537+ 83 Linux /dev/sda2 1 150 1204843+ 82 Linux swap Partition table entries are not in disk order
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 [root@db1 /]# 3.格式化 /dev/sdb1 分区,代码如下:
[root@db1 /]# mkfs -t ext3 /dev/sdb1 mke2fs 1.35 (28-Feb-2004) 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
This filesystem will be automatically checked every 30 mounts or 180 days, whichever comes first. Use tune2fs -c or -i to override. 4.创建目录 并将 /dev/sdb1 挂在到该目录下,代码如下:
[root@db1 /]# ls backup dev initrd media opt sbin sys usr bin etc lib misc proc selinux tftpboot var boot home lost+found mnt root srv tmp [root@db1 /]# mkdir /u01 [root@db1 /]# ls backup dev initrd media opt sbin sys u01 bin etc lib misc proc selinux tftpboot usr boot home lost+found mnt root srv tmp var [root@db1 /]# mount /dev/sdb1 /u01 5.验证挂载是否成功,代码如下:
[root@db1 /]# df -k Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda1 9131772 7066884 1601012 82% / none 454256 0 454256 0% /dev/shm /dev/sdb1 5154852 43040 4849956 1% /backup 6.设置开机自动挂载,代码如下:
[root@db1 /]# vi /etc/fstab # This file is edited by fstab-sync - see ’man fstab-sync’ for details LABEL=/ / ext3 defaults 1 1 none /dev/pts devpts gid=5,mode=620 0 0 none /dev/shm tmpfs defaults 0 0 none /proc proc defaults 0 0 none /sys sysfs defaults 0 0 LABEL=SWAP-sda2 swap swap defaults 0 0 /dev/sdb1 /u01 ext3 defaults 0 0 /dev/hdc /media/cdrom auto pamconsole,exec,noauto,m anaged 0 0 --phpfensi.com /dev/fd0 /media/floppy auto pamconsole,exec,noauto,m anaged 0 0。
