Google Cloud Platform Increase Boot Disk on Virtual Machine

Solution

Should be increase boot size and not work if you want to downgrade boot size

Resize the Disk in GCP Console:

Go To Cloud Shell, then write this

DISK_NAME = "Test"

ZONE_NAME = "example-asia"

SIZE_INCREASE = "50GB"

gcloud compute disks resize DISK_NAME --size SIZE_INCREASE --zone ZONE_NAME

Connect to your SSH

YOUR_VM_INSTANCE_NAME = "TEST VM"

gcloud compute ssh YOUR_VM_INSTANCE_NAME

Open Parted

sudo parted /dev/sda

Print parted

print

Resize the Partition

resizepart 1 100%

Exit Parted

quit

Resize the Filesystem (for ext4 work on linux ubuntu)

sudo resize2fs /dev/sda1

Update /etc/fstab

sudo blkid

Edit fstab

sudo nano /etc/fstab

Option 1 : using UUID

UUID=your-root-uuid  /  ext4  defaults  0  1

Option 2 : using LABEL

LABEL=your-label  /  ext4  defaults  0  1

Test Configuration
