Mounting Hard Disk on Ubuntu

by alamster in July 7th, 2008

One of our server need to reconfigure. Install ubuntu server on it and will convert other hardisk for special purpose on vmware appliance.

In fact the server have 4 HD, 1 for system and 3 HD dedicated for virtual appliance.

This steps taken to format and mounting :

1. See current mount point and space .

2. See all attached HD and its file system.

root@ubuntuserver:/home/edpteam# fdisk -l

Disk /dev/sda: 146.8 GB, 146815737856 bytes
255 heads, 63 sectors/track, 17849 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0×00000000

Device Boot Start End Blocks Id System
/dev/sda1 * 1 17849 143372061 a5 FreeBSD

Disk /dev/sdb: 146.8 GB, 146815737856 bytes
255 heads, 63 sectors/track, 17849 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0×0f8000b1

Disk /dev/sdc: 146.8 GB, 146815737856 bytes
255 heads, 63 sectors/track, 17849 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

255 heads, 63 sectors/track, 17849 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0×90909090

Device Boot Start End Blocks Id System

/dev/sdd3 8512 17119 69143760 83 Linux

Partition table entries are not in disk order
root@ubuntuserver:/home/edpteam#

3. New HD layout scenario.

System in sda
Proxy in sdb -> /proxy
SandboxProgramming in sdc -> /probox
SandboxNetworking in sdd -> /netbox

4. Format each HD :

root@ubuntuserver:/home/edpteam# mkfs -t ext3 /dev/sda
mke2fs 1.40.8 (13-Mar-2008)
/dev/sda is entire device, not just one partition!
Proceed anyway? (y,n) y

Proceed anyway? (y,n) y
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
8962048 inodes, 35843686 blocks
1792184 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=0
1094 block groups
32768 blocks per group, 32768 fragments per group
8192 inodes per group
Superblock backups stored on blocks:
32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208,
4096000, 7962624, 11239424, 20480000, 23887872

Writing inode tables: done
Creating journal (32768 blocks): done
Writing superblocks and filesystem accounting information: done

This filesystem will be automatically checked every 26 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.
root@ubuntuserver:/home/edpteam#

Repeat this step for other HD .

4. Make mounting point for those HD.

Mounting point

root@ubuntuserver:/home/edpteam# mkdir /proxy
root@ubuntuserver:/home/edpteam# mkdir /probox
root@ubuntuserver:/home/edpteam# mkdir /netbox

Mounting to system.

root@ubuntuserver:/home/edpteam# mount -t ext3 /dev/sda /proxy
root@ubuntuserver:/home/edpteam# mount -t ext3 /dev/sdb /probox
root@ubuntuserver:/home/edpteam# mount -t ext3 /dev/sdc /netbox

Check if the HDs already mounted. (using command mount or df)

root@ubuntuserver:/home/edpteam# df -H
Filesystem Size Used Avail Use% Mounted on
/dev/sdd1 67G 622M 63G 1% /
varrun 1.1G 46k 1.1G 1% /var/run
varlock 1.1G 0 1.1G 0% /var/lock
udev 1.1G 95k 1.1G 1% /dev
devshm 1.1G 0 1.1G 0% /dev/shm
/dev/sda 146G 197M 139G 1% /proxy
/dev/sdb 146G 197M 139G 1% /probox
/dev/sdc 146G 197M 139G 1% /netbox

5. Make permanent routing, just edit /etc/fstab

root@ubuntuserver:/home/edpteam# nano /etc/fstab

Save the file.

6. Done, next step is install Vmware server
