First, you will need to run the fdisk command in order to partition the disk. For this example, I only want to create one ext3 partition. Here is an example session:[root@linux2 etc]# fdisk /dev/hdbDevice contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabelBuilding a new DOS disklabel. Changes will remain in memory only,until you decide to write them. After that, of course, the previouscontent won't be recoverable.The number of cylinders for this disk is set to 4865.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): nCommand action e extended p primary partition (1-4) pPartition number (1-4): 1First cylinder (1-4865, default 1): 1Last cylinder or +size or +sizeM or +sizeK (1-4865, default 4865): 4865Command (m for help): tPartition number (1-4): 1Hex code (type L to list codes): 83Command (m for help): wThe partition table has been altered!Calling ioctl() to re-read partition table.Syncing disks.
The next step is to create an ext3 file system on the new partition. Provided with the distribution is a script named /sbin/mkfs.ext3. Here is an example session of using the mkfs.ext3 script:[root@linux2 root]# mkfs.ext3 -b 4096 /dev/hdb1mke2fs 1.27 (8-Mar-2002)Filesystem label=OS type: LinuxBlock size=4096 (log=2)Fragment size=4096 (log=2)4889248 inodes, 9769520 blocks488476 blocks (5.00%) reserved for the super userFirst data block=0299 block groups32768 blocks per group, 32768 fragments per group16352 inodes per groupSuperblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208, 4096000, 7962624Writing inode tables: doneCreating journal (8192 blocks): doneWriting superblocks and filesystem accounting information: doneThis filesystem will be automatically checked every 36 mounts or180 days, whichever comes first. Use tune2fs -c or -i to override.
Now that the new hard drive is partition and formated, the last step is to mount the new drive. For this example, I will be mounting the new hard drive on the directory /db.
NOTE: You will first need to create the /db directory before mouting the disk! (e.g. mkdir /db)
What I typically do is to edit the /etc/fstab file and add an entry for the new drive. For my example, I will create the /dev/hdb1 entry as follows:LABEL=/ / ext3 defaults 1 1LABEL=/boot /boot ext3 defaults 1 2none /dev/pts devpts gid=5,mode=620 0 0none /proc proc defaults 0 0none /dev/shm tmpfs defaults 0 0/dev/hdb1 /db ext3 defaults 1 1/dev/hda2 swap swap defaults 0 0/dev/cdrom /mnt/cdrom iso9660 noauto,owner,kudzu,ro 0 0/dev/fd0 /mnt/floppy auto noauto,owner,kudzu 0 0After making the entry in the /etc/fstab file, it is now just a matter of mounting the disk:[root@linux2 /]# mount /db[root@linux2 /]# df -kFilesystem 1K-blocks Used Available Use% Mounted on/dev/hda3 37191660 11016692 24285724 32% //dev/hda1 101089 12130 83740 13% /bootnone 515524 0 515524 0% /dev/shm/dev/hdb1 38464340 32828 36477608 1% /db
