I'm trying to resize my disk that's on google cloud from 1TB to 2 TB. I resized the disk space in google's console as instructed and:

df -h

Filesystem Size Used Avail Use% Mounted on
overlay 95G 7.1G 88G 8% /
tmpfs 16G 0 16G 0% /dev
tmpfs 16G 0 16G 0% /sys/fs/cgroup
/dev/sda1 95G 7.1G 88G 8% /etc/hosts
shm 64M 0 64M 0% /dev/shm
/dev/sdg 984G 381G 554G 41% /var/lib/data
tmpfs 16G 12K 16G 1% /run/secrets/kubernetes.io/serviceaccount
tmpfs 16G 0 16G 0% /sys/firmware

and:

lsblk

sdg 8:96 0 2T 0 disk /var/lib/data

now i tried to use resize2fs to resize and got:

resize2fs /dev/sdg

resize2fs 1.42.12 (29-Aug-2014)
open: No such file or directory while opening /dev/sdg

AFAIK /dev/sdg is the raw device - /dev/sdg1 is a virtual device, a partition for example.

This will show in fdisk -l. If it's not mounted you can use resize2fs on /dev/sdg1 if it's ext2, ext3 or ext4 formated other filesystems btrfs etc. are most likely are not supported.
