Question

A Compute Engine VM running Ubuntu has a boot disk that is nearly full. Your team decides to increase the boot disk size from 20 GB to 100 GB. You use the Cloud Console to resize the persistent disk to 100 GB, but after rebooting, the operating system still reports only 20 GB of available space. What should you do to make the additional space usable?

Accepted Answer

Grow the partition and resize the file system on the running VM (e.g., using growpart and resize2fs).

Answer

Detach the disk and reattach it so the guest OS re-reads the new capacity.

Answer

Create a snapshot of the disk and restore it to a new 100 GB disk.

Answer

Change the disk type from standard persistent disk to SSD persistent disk.
