To verify the file system and type for each volume, use the df -hT command.

df -hT

To check whether the volume has a partition that must be extended, use the lsblk command to display information about the NVMe block devices attached to your instance.

lsblk

For volumes that have a partition, such as the root volume shown in the previous step, use the growpart command to extend the partition. Notice that there is a space between the device name and the partition number

growpart /dev/nvme0n1 1

To extend the file system on each volume, use the resize2fs command

resize2fs /dev/nvme0n1p1

To verify that each file system reflects the increased volume size, use the df -h command again.

df -h

(Root Partition Alerts on Nagios would be based on the volume of the Instances)
