Created 100GB ec2 instance, but only shows 10GB?

I just created a new EC2 instance of 100gb with only 1 storage disk.

However, my df -h output shows the following :

[root@ip-10-252-37-164 ~]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/xvde1            5.5G  2.9G  2.3G  56% /
tmpfs                 296M     0  296M   0% /dev/shm
[root@ip-10-252-37-164 ~]#

How is this possible ? Where is the rest 90GB of my disk ? How do I get the full 100G on /dev/xvde1 ?

lsblk gives me this output :

[root@ip-10-252-37-164 ~]# lsblk
NAME    MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
xvde    202:64   0   100G  0 disk
├─xvde1 202:65   0   5.5G  0 part /
└─xvde2 202:66   0 488.7M  0 part [SWAP]
[root@ip-10-252-37-164 ~]#

I tried using resize2fs, but I get this error :

[root@ip-10-252-37-164 ~]# resize2fs /dev/xvde1
resize2fs 1.41.12 (17-May-2010)
The filesystem is already 1447753 blocks long.  Nothing to do!

Solution 1:

The space exists on the disk, you just need to make it available. The simplest thing to do here is to

• Use fdisk to create a new partition
• Create a filesystem using mkfs
• Add the new partition into a convenient filesystem location using mount.
• Update the /etc/fstab as appropriate.
