Use the df -h command to verify that the root partition mounted under "/" is full (100%). In the following example, /dev/nvme0n1p1 is using 100% of its space.
[ec2-user ~]$ df -h
Filesystem Size Used Avail Use% Mounted on
devtmpfs 460M 0 475M 0% /dev
tmpfs 478M 0 492M 0% /dev/shm
tmpfs 478M 432K 492M 1% /run
tmpfs 478M 0 492M 0% /sys/fs/cgroup
/dev/nvme0n1p1 8.0G 8.0G 664K 100% /
tmpfs 96M 0 99M 0% /run/user/1000
If you are running on aws cloud, you can extend the root EBS Volume in AWS Console (ec2 console) or CLI, read here https://aws.amazon.com/premiumsupport/knowledge-center/expand-ebs-root-volume-windows/
The following example shows that the root EBS volume block device (/dev/nvme0n1) is 9 GiB, and the root partition (partition 1) is already 8 GiB (partition is 100% used).
$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
nvme0n1 259:0 0 9G 0 disk
├─nvme0n1p1 259:1 0 8G 0 part /
└─nvme0n1p128 259:2 0 1M 0 part
If you attempt to increase the root partition (partition 1), you receive one of the following errors:
$ sudo growpart /dev/nvme0n1 1
/bin/growpart: line 248: /tmp/growpart.fklt5u/dump.out: No space left on device
FAILED: failed to dump sfdisk info for /dev/nvme0n1
-or-
$ sudo growpart /dev/nvme0n1 1
CHANGED: partition=1 start=4096 old: size=16773087 end=16777183 new: size=18870239 end=18874335
FAILED: failed: sfdisk --list /dev/nvme0n1
To avoid a No space left on the block device error, mount the temporary file system tmpfs to the /tmp mount point. This creates a 10 M tmpfs mounted to /tmp.
$ sudo mount -o size=10M,rw,nodev,nosuid -t tmpfs tmpfs /tmp
then try again run the growpart command to grow the size of the root partition or partition 1. Replace /dev/nvme0n1 with your root partition.
$ sudo growpart /dev/nvme0n1 1
CHANGED: partition=1 start=4096 old: size=16773087 end=16777183 new: size=18870239 end=18874335
Run the lsblk command to verify that partition 1 is expanded to 9 GiB.
$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
nvme0n1 259:0 0 9G 0 disk
├─nvme0n1p1 259:1 0 9G 0 part /
└─nvme0n1p128 259:2 0 1M 0 part
then, run resize2fs to expand the file system
sudo resize2fs /dev/nvme0n1p1
After expanding the file system, use the df -h command to verify that the OS can see the additional space (partition is 89% used).
$ df -h
Filesystem Size Used Avail Use% Mounted on
devtmpfs 960M 0 960M 0% /dev
tmpfs 978M 0 978M 0% /dev/shm
tmpfs 978M 392K 978M 1% /run
tmpfs 978M 0 978M 0% /sys/fs/cgroup
/dev/nvme0n1p1 9.0G 8.0G 1022M 89% /
tmpfs 196M 0 196M 0% /run/user/1000
tmpfs 10M 0 10M 0% /tmp
Run the unmount command to unmount the tmpfs file system.
$ sudo umount /tmp
