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 the 15GB capacity. What's 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?
