root@ip-172-31-46-249:~# parted -l Model: NVMe Device (nvme) Disk /dev/nvme0n1: 21.5GB Sector size (logical/physical): 512B/512B Partition Table: msdos Disk Flags: Number Start End Size Type File system Flags 1 1049kB 10.7GB 10.7GB primary ext4 boot root@ip-172-31-46-249:~# |
The partition still shows 10 GB. When i try growpart, i get error

This is because disk is full. I try delete some unwanted files. But was not able to free up much disk space. To fix the error, i mounted /tmp in memory with commands.

mkdir /dev/shm/tmp chmod 1777 /dev/shm/tmp mount --bind /dev/shm/tmp /tmp |
This ec2 instance had lot of free RAM, so it should handle /tmp folder with out any issue. Now growpart worked.

parted -l shows the partition using all available disk space

still df -h won’t show increased disk space, this is because you need to increase filesystem size.
