Amazon EC2 and EBS disk space problem


I am having a problem reconciling the space available on my EBS volume. According to the AWS console the volume is 50GB and is attached to an instance.

If I ssh to this instance and do a df -h, I get the following output:

Filesystem            Size  Used Avail Use% Mounted on
/dev/sda1              15G   13G  3.0G  81% /
udev                  858M   76K  858M   1% /dev
none                  858M     0  858M   0% /dev/shm
none                  858M   72K  858M   1% /var/run
none                  858M     0  858M   0% /var/lock
none                  858M     0  858M   0% /lib/init/rw

I am pretty new to AWS. I interpret this as "there is a device attached and it has 15GB capacity. Whats more, you're nearly out of space!"

Can anyone point out the cause of the apparent discrepancy between the space advertised in the console and what is displayed on the instance?

Many thanks in advance

Solution

  • Perhaps the original 15 GB Volume was cloned into a 50 GB volume but then not resized?

    Please see this tutorial on how to clone and resize: How to increase disk space on existing AWS EC2 Linux (Ubuntu) Instance without losing data

    Hope that helps.
