  • To check whether the volume has a partition that must be extended, use the lsblk command to display information
thirumal:~/environment $ lsblk

  • The above output shows, xvda has one partition
  • Extend/Grow the partition
sudo growpart /dev/xvda 1

(OR)
sudo growpart /dev/nvme0n1 1

or

# resize filesystem
thirumal.mari:~/environment $ sudo resize2fs /dev/xvda1
