After the login on the ubuntu, set the rights for the root user:

extend the harddisk hdd linux ubuntu:

command for status hdd

Command:

> lsblk -o NAME,FSTYPE,SIZE,MOUNTPOINT,LABEL

Output:

NAME FSTYPE SIZE MOUNTPOINT LABEL

xvda 8G

└─xvda1 ext4 8G / cloudimg-rootfs

Coommand :

> fdisk -l

Output:

Disk /dev/xvda: 8589 MB, 8589934592 bytes

255 heads, 63 sectors/track, 1044 cylinders, total 16777216 sectors

Units = sectors of 1 * 512 = 512 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

Check the link here:

See the status of the linux device:

root@ip-10-0-0-4:~# file -s /dev/xvda1*

/dev/xvda1: Linux rev 1.0 ext4 filesystem data, UUID=d4f2aafc-946a-4514-930d-4c45e676f198, volume name “cloudimg-rootfs” (needs journal recovery) (extents) (large files) (huge files)

Then see all the partitions again:

root@ip-10-0-0-4:~# lsblk

NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT

xvda 202:0 0 8G 0 disk

└─xvda1 202:1 0 8G 0 part /

In order to see the usage percentage of the disk run the following command:

root@ip-10-0-0-4:~# df

Filesystem 1K-blocks Used Available Use% Mounted on

udev 502980 12 502968 1% /dev

tmpfs 101632 356 101276 1% /run

/dev/xvda1 8115168 6167760 1512132 81% /

none 4 0 4 0% /sys/fs/cgroup

none 5120 0 5120 0% /run/lock

none 508152 0 508152 0% /run/shm

none 102400 0 102400 0% /run/user

Then change the size of the disk

Then you can see the changed size:

Then in the command prompt you have to see the new size

Then you have to increase the size of the current partition
