Adding New Hard Disk On Linux Box

Linux stores all the known disk partition in /proc/partitions file

The Entire hard disk is represented by a entry with minor number 0, the partitions on the drive are sequentially numbered after that.

We have added a new hard disk and it is represented as /dev/hdb

Partitioning the new disk :

The first steo after adding the new disk is to partition it in preparation of the adding a filesystem to it.

#fdisk /dev/hdb

Make the Hard Disk as primary partition

Enter all the default values

Once done type "p" and check for the details

Then to save the changes type "w"

To verify the new partition

#cat /proc/partitions

Putting the directory structure on the newly formatted hard disk

#mkfs -t ext3 /dev/hdb1

#mkdir /mnt/hdb

To automatically mount the partition

#vi /etc/fstab

/dev/hdb1 /mnt/hdb1 ext3 defaults 1 2

Mount the partition

#mount -a
