My EC2 micro instance volume growing fast and it comes to a critical level now:
$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/xvda1 7.9G 7.2G 343M 96% /
udev 289M 4.0K 289M 1% /dev
tmpfs 119M 164K 119M 1% /run
none 5.0M 0 5.0M 0% /run/lock
none 297M 0 297M 0% /run/shm
Took me some time to upgrade the volume and would like to share with all.
First, login onto AWS Management Console, navigate to EC2 tab, and follow by Elastic Block Store > Volumes.
Create a snapshot from the volume by giving a name and a description.
Next, nagivate to Elastic Block Store > Snapshots and wait for the progress to be done.
After the progress is done, create a volume from the snapshot by giving a new size.
Next, you will need to shutdown and stop your instance before you can detach the old volume and attach the new volume.
$ sudo shutdown now
Navigate to Instances to stop your instance. (Stop means Stop, not Terminate or your instance will be gone)
After a while, go back to Volumes and write down your in-use
volume’s attachment information; where my Ubuntu’s volume is attached to /dev/sda1
.
Next, detach the old in-use
volume and attach the newly created available
volume.
Start your instance again from Instances.
Login into shell before proceeding to the last step.
$ sudo resize2fs /dev/xvda1
After a short while, you are done!
$ df -h
