同時新增多組帳號及Disk Quota limit的實驗 (三)

• LAB B :

4. 建立 檔案系統/dev/hda5(容量100MB)。
5. /dev/hda5的檔案系統格式為 ext3。
6. 將/dev/hda5 掛載到 /media/hda5。

• 操作步驟 :

         STEP 1. 確認硬碟裝置檔檔名

[root@lab-2 ~]# fdisk -l Disk /dev/hdb: 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/hdb1 * 1 13 104391 83 Linux /dev/hdb2 14 778 6144862+ 83 Linux /dev/hdb3 779 909 1052257+ 82 Linux swap / Solaris

STEP 2. 執行 fdisk 劃分檔案系統

[root@lab-2 ~]# fdisk /dev/hdb

STEP 3. 執行 fdisk 劃分檔案系統

[root@lab-2 ~]# fdisk /dev/hdb

STEP 4. 新增延伸分割區 /dev/hdb4

Command (m for help): p Disk /dev/hdb: 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/hdb1 * 1 13 104391 83 Linux /dev/hdb2 14 778 6144862+ 83 Linux /dev/hdb3 779 909 1052257+ 82 Linux swap / Solaris Command (m for help): n Command action e extended p primary partition (1-4) e Selected partition 4 First cylinder (910-1044, default 910): Using default value 910 Last cylinder or +size or +sizeM or +sizeK (910-1044, default 1044): Using default value 1044 Command (m for help): p Disk /dev/hdb: 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/hdb1 * 1 13 104391 83 Linux /dev/hdb2 14 778 6144862+ 83 Linux /dev/hdb3 779 909 1052257+ 82 Linux swap / Solaris /dev/hdb4 910 1044 1084387+ 5 Extended

STEP 5. 新增邏輯分割區 /dev/hdb5(容量 100MB)

Command (m for help): n First cylinder (910-1044, default 910): Using default value 910 Last cylinder or +size or +sizeM or +sizeK (910-1044, default 1044): +100M Command (m for help): p Disk /dev/hdb: 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/hdb1 * 1 13 104391 83 Linux /dev/hdb2 14 778 6144862+ 83 Linux /dev/hdb3 779 909 1052257+ 82 Linux swap / Solaris /dev/hdb4 910 1044 1084387+ 5 Extended /dev/hdb5 910 922 104391 83 Linux

STEP 6. 儲存變更後的Partition Table並使用 partprobe 進行同步作業使New Partition Table 生效

(或重啟系統使New Partition Table 生效)

Command (m for help): w The partition table has been altered! Calling ioctl() to re-read partition table. WARNING: Re-reading the partition table failed with error 16: Device or resource busy. The kernel still uses the old table. The new table will be used at the next reboot. Syncing disks. You have new mail in /var/spool/mail/root [root@lab-2 ~]# partprobe

STEP 7. 將 /dev/hdb5 格式化為 ext3 檔案系統

[root@lab-2 ~]# mkfs -t ext3 /dev/hdb5 mke2fs 1.39 (29-May-2006) Filesystem label= OS type: Linux Block size=1024 (log=0) Fragment size=1024 (log=0) 26104 inodes, 104388 blocks 5219 blocks (5.00%) reserved for the super user First data block=1 Maximum filesystem blocks=67371008 13 block groups 8192 blocks per group, 8192 fragments per group 2008 inodes per group Superblock backups stored on blocks: 8193, 24577, 40961, 57345, 73729 Writing inode tables: done Creating journal (4096 blocks): done Writing superblocks and filesystem accounting information: done This filesystem will be automatically checked every 31 mounts or 180 days, whichever comes first. Use tune2fs -c or -i to override. [root@lab-2 ~]# dumpe2fs /dev/hdb5 | grep 'Filesystem features:' dumpe2fs 1.39 (29-May-2006) Filesystem features: has_journal resize_inode dir_index filetype sparse_super [root@lab-2 ~]#

STEP 8. 建立掛載點 /media/hdb5

[root@lab-2 ~]# ls -ld /media/hdb5 ls: /media/jdb5: No such file or directory [root@lab-2 ~]# mkdir /media/hdb5 [root@lab-2 ~]# ls -ld /media/hdb5 drwxr-xr-x 2 root root 4096 Dec 6 15:21 /media/hdb5

STEP 9. 將/dev/hdb5 掛載到 /media/hdb5 並確認掛載選項正確

[root@lab-2 ~]# mount -t ext3 -o usrquota,grpquota /dev/hdb5 /media/hdb5/ [root@lab-2 ~]# mount | grep hdb5 /dev/hdb5 on /media/hdb5 type ext3 (rw,usrquota,grpquota)
