xvda1 is 100% full, What is it? how to fix?

Solution 1:

That file, / is your root directory. If it's the only filesystem you see in df, then it's everything. You have a 1GB filesystem and it's 100% full. You can start to figure out how it's used like this:

sudo du -x / | sort -n | tail -40

You can then replace / with the paths that are taking up the most space. (They'll be at the end, thanks to the sort. The command may take awhile.)

Solution 2:

I know i am replying in this thread after nearly 5 years but it might help someone, I had the same problem, i had m4.xlarge instance df -h told that the /dev/xvda1 was full, - 100%

Filesystem      Size  Used Avail Use% Mounted on
udev            7.9G     0  7.9G   0% /dev
tmpfs           1.6G  177M  1.4G  12% /run
/dev/xvda1      7.7G  7.7G     0 100% /
tmpfs           7.9G     0  7.9G   0% /dev/shm
tmpfs           5.0M     0  5.0M   0% /run/lock
tmpfs           7.9G     0  7.9G   0% /sys/fs/cgroup
tmpfs           1.6G     0  1.6G   0% /run/user/1000

i tried to solve it here are the steps

sudo find / -type f -printf '%12s %p\n' 2>/dev/null|awk '{if($1>999999999)print $0;}'

Helped me to know that it was the docker container that was talking all my space so i push all my container to my docker registry then did sudo rm -rf /var/lib/docker/ it cleared up my space :) hope it helps someone :)

If you are running an EBS boot instance (recommended) then you can increase the size of the root (/) volume using the procedure I describe in this article:

Resizing the Root Disk on a Running EBS Boot EC2 Instance
http://alestic.com/2010/02/ec2-resize-running-ebs-root

If you are running an instance-store instance (not recommended) then you cannot change the size of the root disk. You either have to delete files or move files to ephemeral storage (e.g., /mnt) or attach EBS volumes and move files there.

Here's an article I wrote that describes how to move a MySQL database from the root disk to an EBS volume:

Running MySQL on Amazon EC2 with EBS

...and consider moving to EBS boot instances. There are many reasons why you'll thank yourself later.
