New Linux Disk

To add a new disk drive to (ubuntu) linux system, do this (Ubunu Community Documentation - Installing A New Hard Drive):

• sudo bash # need to run as root
• lshw -C disk # to list drives in the machine
  • From lshw find the logical name of the new drive. Say /dev/sdb
• fdisk /dev/sdb # create a partition table
  • n # new partition
  • p # primary partition
  • 1 # partition 1
  • w # write partition table to disk
• mkfs -t ext4 /dev/sdb1 # make an ext4 filesystem, on partition 1 of disk
• tune2fs -m 1 /dev/sdb1 # change reserved blocks to only 1%
• e2label /dev/sdb1 "ext4_2TB_a_WhateverYouWant" # label the new filesystem
• cfdisk /dev/sdb # have a look at the partition table
• mkdir /media/disk1 # create a mount point
• chmod 777 /media/disk1 # make it writeable by everyone
• edit /etc/fstab, add this (so disk is mounted at reboot):
  • /dev/sdb1 /media/disk1 ext4 defaults 0 2
• mount /dev/sdb1

If you want to share the drive via Samba, edit /etc/samba/smb.conf :

[disk2]
comment = Disk 2
path = /media/disk2
public = yes
writable = yes
create mask = 0664
directory mask = 0775
force user = rk
force group = rk
