The root disk of this web site is running out of space. I completed the steps below to add 10Gb as 2nd disk for storing data.
Create disk
- Click the VM instances I want to add disk space
- Click "Edit"
- Click "+ Add item" under "Additional disks"
- Select "Create disk" in the drop down menu
- Set the name of the disk
- Select "Source type" as "Nonde (blank disk)" and Size (BG) = 10
Mount disk
- ssh login to the VM instance
- sudo mkdir -p /mnt/disks/[MNT_DIR]
- Find the disk just created
- ls /dev/disk/by-id/
- Format the disk
- sudo mkfs.ext4 -F /dev/disk/by-id/google-[DISK]
- Mount the disk
- sudo mount -o discard,defaults /dev/disk/by-id/google-[DISK] /mnt/disks/[MNT_DIR]
- Find the UUID of the disk
- sudo blkid -s UUID -o value /dev/disk/by-id/google-[DISK]
- Add this link in /etc/fstab
- UUID=[DISK_UUID] /mnt/disk/[MNT_DIR] ext4 defaults 0 0
