How to increase AWS EBS NVME size

Question

I have upgraded an EC2 instance from m4 to m5, and now I want to increase the volume.

I did perform this command and got the error:

growpart /dev/nvme0n1         


        

Answer 1

resize2fs didn't work for me, so I used this instead:

xfs_growfs /dev/nvme0n1p1

resize2fs gave me this error when I used it:

[root@ip-1-2-3-4 ~]# resize2fs /dev/nvme0n1p1
resize2fs 1.42.9 (28-Dec-2013)
resize2fs: Bad magic number in super-block while trying to open /dev/nvme0n1p1
Couldn't find valid filesystem superblock.

I noticed the disk was using xfs under /etc/fstab:

UUID=4cbf4a19-1fba-4027-bf92-xxxxxxxxxxxx     /           xfs    defaults,noatime  1   1
