This will show you all of the attached drives on the system
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:
fdisk /dev/hdb 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 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): n Command action e extended p primary partition (1-4) p Partition number (1-4): 1 First cylinder (1-4865, default 1): 1 Last cylinder or +size or +sizeM or +sizeK (1-4865, default 4865): 4865 Command (m for help): t Partition number (1-4): 1 Hex code (type L to list codes): 83 Command (m for help): w The partition table has been altered! Calling ioctl() to re-read partition table. Syncing disks.</pre> <strong>Create ext3 File System</strong> 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: <pre>mkfs.ext3 -b 4096 /dev/hdb1 mke2fs 1.27 (8-Mar-2002) Filesystem label= OS type: Linux Block size=4096 (log=2) Fragment size=4096 (log=2) 4889248 inodes, 9769520 blocks 488476 blocks (5.00%) reserved for the super user First data block=0 299 block groups 32768 blocks per group, 32768 fragments per group 16352 inodes per group Superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208, 4096000, 7962624 Writing inode tables: done Creating journal (8192 blocks): done Writing superblocks and filesystem accounting information: done This filesystem will be automatically checked every 36 mounts or 180 days, whichever comes first. Use tune2fs -c or -i to override.
Mounting the File System
Now that the new drive(s) are partitioned and formatted, the last step is to mount the new drive(s). Typically on Ubuntu they will be in the /mnt directory.
I create a folder to mount the drives in the /mnt directory: mkdir nfs or mkdir right_raid
Below is the output from the /etc/fstab file note the entries I made:
# /etc/fstab: static file system information. # # proc /proc proc defaults 0 0 # /dev/sda1 UUID=9856bbea-a089-475f-ab29-1b976a666869 / ext3 relatime,errors=remount-ro 0 1 # /dev/sda5 UUID=2ad62d1d-e91f-4d48-8830-c5f32c8a5c56 none swap sw 0 0 /dev/scd1 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0 /dev/scd0 /media/cdrom1 udf,iso9660 user,noauto,exec,utf8 0 0 #Xserve RAID #/dev/sdc1 /mnt/left_raid ext3 defaults 0 0 #/dev/sdb1 /mnt/right_raid ext3 defaults 0 0 /dev/sdb1 /mnt/nfs ext3 defaults 0 0 /dev/sdg1 /mnt/right_raid ext3 defaults 0 0
After making the entry in the /etc/fstab file, it is now just a matter of mounting the disk:
Mount drive, You might want to create the actual mkdir you want to attach the drive to like creating a drive letter name
mount /db df -k Filesystem 1K-blocks Used Available Use% Mounted on /dev/hda3 37191660 11016692 24285724 32% / /dev/hda1 101089 12130 83740 13% /boot none 515524 0 515524 0% /dev/shm /dev/hdb1 38464340 32828 36477608 1% /db
mount /dev/sdc1 /mnt/right_raid -t ext3
Thanks to a friend of mine for the information about CFDISK which is a semi graphical utility to partition drives.
