首先检查硬盘，分区格式化 [root@localhost ~]# fdisk -l Disk /dev/sda: 8589 MB, 8589934592 bytes 255 heads, 63 sectors/track, 1044 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 78 522112+ 82 Linux swap / Solaris /dev/sda3 79 1044 7759395 83 Linux Disk /dev/sdb: 8589 MB, 8589934592 bytes 255 heads, 63 sectors/track, 1044 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk /dev/sdb doesn't contain a valid partition table [root@localhost ~]# fdisk /dev/sdb Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklab el 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 1044. 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): n Command action e extended p primary partition (1-4) p Partition number (1-4): 1 First cylinder (1-1044, default 1): Using default value 1 Last cylinder or +size or +sizeM or +sizeK (1-1044, default 1044): Using default value 1044 Command (m for help): w The partition table has been altered! Calling ioctl() to re-read partition table. Syncing disks. [root@localhost ~]# 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) 1048576 inodes, 2096474 blocks 104823 blocks (5.00%) reserved for the super user First data block=0 Maximum filesystem blocks=2147483648 64 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 Writing inode tables: done Creating journal (32768 blocks): done Writing superblocks and filesystem accounting information: done This filesystem will be automatically checked every 34 mounts or 180 days, whichever comes first. Use tune2fs -c or -i to override. 检查系统内核对磁盘配额的支持 [root@localhost ~]# dmesg |grep quota VFS: Disk quotas dquot_6.5.1 [root@localhost ~]# rpm -qa |grep quota quota-3.13-1.2.3.2.el5 [root@localhost ~]# mount /dev/sdb1 /mnt/ [root@localhost ~]# cp -a /home/* /mnt/ [root@localhost ~]# ll /mnt total 20 drwx------ 2 root root 16384 Feb 20 00:29 lost+found drwx------ 2 redhat redhat 4096 Aug 17 2008 redhat [root@localhost ~]# rm -rf /home/redhat [root@localhost ~]# ll /home total 0 [root@localhost ~]# vim /etc/fstab LABEL=/ / ext3 defaults 1 1 LABEL=/boot /boot ext3 defaults 1 2 devpts /dev/pts devpts gid=5,mode=620 0 0 tmpfs /dev/shm tmpfs defaults 0 0 proc /proc proc defaults 0 0 sysfs /sys sysfs defaults 0 0 LABEL=SWAP-sda2 swap swap defaults 0 0 /dev/sdb1 /home ext3 defaults,usrquota,grpquota 0 1 重启 [root@localhost ~]# reboot 重启后检查是否配置正确 [root@localhost ~]# mount /dev/sda3 on / type ext3 (rw) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) devpts on /dev/pts type devpts (rw,gid=5,mode=620) /dev/sda1 on /boot type ext3 (rw) tmpfs on /dev/shm type tmpfs (rw) /dev/sdb1 on /home type ext3 (rw,usrquota,grpquota) none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw) 开始为用户创建磁盘配额 [root@localhost ~]# quotacheck -acugv quotacheck: Scanning /dev/sdb1 [/home] quotacheck: Cannot stat old user quota file: No such file or directory quotacheck: Cannot stat old group quota file: No such file or directory quotacheck: Cannot stat old user quota file: No such file or directory quotacheck: Cannot stat old group quota file: No such file or directory done quotacheck: Checked 4 directories and 5 files quotacheck: Old file not found. quotacheck: Old file not found.
