[All Professional Cloud Database Engineer Questions]

Your organization is running a critical production database on a virtual machine (VM) on Compute Engine. The VM has an ext4-formatted persistent disk for data files. The database will soon run out of storage space. You need to implement a solution that avoids downtime. What should you do?

  • A. In the Google Cloud Console, increase the size of the persistent disk, and use the resize2fs command to extend the disk.
  • B. In the Google Cloud Console, increase the size of the persistent disk, and use the fdisk command to verify that the new space is ready to use
  • C. In the Google Cloud Console, create a snapshot of the persistent disk, restore the snapshot to a new larger disk, unmount the old disk, mount the new disk, and restart the database service.
  • D. In the Google Cloud Console, create a new persistent disk attached to the VM, and configure the database service to move the files to the new disk.

A. Using fdisk by itself won’t achieve anything. A is wrong. Snapshotting a disk with database instances in flight is a potential problem. C is wrong. D, with some tweaking could move things to a larger disk, but there would be downtime. D is therefore wrong. There are several steps to achieving this task and they start with A. The link provided by chelbsik is spot on.
