vCloud Availability – Resizing Disk of Protected VM

A customer asked how to resize a disk of very large VM (file server) which is protected with vCloud Availability and thus replicated to the cloud.

It is not straight forward as the underlying replication engine relies on tracking changed blocks and both the source and target disks must have the same size. In short the replication must be stopped for a moment and then re-established after the necessary disk resizing. Here is step by step process:

  1. Fail over VM via vCloud Availability UI/API without powering on the VM (leave on-prem running).
  2. Consolidate the VM in the cloud (this must be done by SP or use workarounds with copy to catalog and deploy back).
  3. Stop replication of on-prem VM (via vSphere UI plugin).
  4. Resize disk of on-prem VM (including partition and file system).
  5. Resize disk of cloud VM from step #2 (only hardware).
  6. Setup replication from scratch by using ‘Use replication seeds’ option while selecting the seed of failed over cloud VM from step #5
