EC2 instance on Amazon and I am greeted with "No space left on the disk"

I have installed Amazon EC2 fedora instance and copying the files from one location to another. But I am greeted with " No space left on the disk".

I did df -f.

with output:

Filesystem            Size  Used Avail Use% Mounted on
/dev/sda1              15G   15G     0 100% /
none                  312M     0  312M   0% /dev/shm

I want to increase the space for ec2 instance on amazon. Can someone help me with it?

Here's an even easier method. (My m2.2xlarge instance was created with RedHat Linux 6.2, I discovered it had a paltry 6gb available of it's 850gb):

1. Via ssh, check space under root: $df -h > Filesystem Size Used Avail Use% Mounted on > /dev/xvde1 6G 6G 0G 100% / > none 17G 0 17G 0% /dev/shm

2. From aws console, stop the instance

3. From aws console, detach the volume (though note the mount point under attachment info, eg /dev/sda1)

4. From aws console, take a snapshot of the volume

5. From aws console, create a new volume using the snapshot (using all the remaining space for the instance type, eg 825gb in my m2.2xlarge case)

6. From aws console, attach the new volume to original mount point /dev/sda1

7. From aws console, restart the instance and ssh back in to the instance

8. From ssh, run resize2fs on the root Filesystem (see df -h output in step 1) [potentially not needed] > $resize2fs /dev/xvde1

9. wait for a few minutes, possibly go and watch your buddy who is stopping [all the root services etc][1] like a boss : )

10. observe the new cavernous mount: $df -h > Filesystem Size Used Avail Use% Mounted on > /dev/xvde1 813G 3.7G 801G 1% / > none 17G 0 17G 0% /dev/shm

Modify volume size. From AWS Console, you can modify the size of a volume.

1. From AWS console, open 'ELASTIC BLOCK STORE/Volume'
2. Select your volume and Modify volume(from Actions button)
3. Change size (e.g. 8 to 20gib)
4. Click Modify.
5. Reboot from EC2 Dashboard.
6. check size is changed by df -h

I got a solution guys yippeeee

Assuming that you are using a linux AMI, in your case you have an easy method for increasing the size of the file system:

1. Stop the instance

2. Detach the root volume

3. Snapshot the volume

4. Create a new volume from the snapshot using the new size

5. Attach the new volume to the instance on the same place where the original one was

6. Start the instance, stop all services except ssh and set the root filesystem read only

7. Enlarge the filesystem (using for example resize2fs) and or the partition if needed

8. Reboot

As an alternative you can also launch a new instance and map the instance storage or you can create a new ami combining the two previous steps.

1. find the biggest files with du -a | sort -n
2. stop some services, they might block hidden/removed files from being finally deleted.

I skipped all the detach/snapshot/new volume stuff... just did the resize.

Filesystem           1K-blocks      Used Available Use% Mounted on

Filesystem at /dev/sda1 is mounted on /; on-line resizing required
Performing an on-line resize of /dev/sda1 to 31457280 (4k) blocks.

I mounted the disk on another EC2 instance where I could successfully use growpart and then resize2fs. After that mounting back to the origin EC2 instance.

Your case is valid when the EC2 instance was created from "EBS-Store" rather than "Instance-Store". EC2 instance created from "instance-store" will always have a huge space (around 200GB +) allocated for /mnt directory.

Otherwise your solution is valid for those EC2 machine created from "EBS-Store". You can do more with such machines.

1. Change the termination type
2. Change the instance type
3. Create an AMI from the instance
4. Auto-scale with ease.
