How can I create a thin-provisioned disk with an initial size?

Solution Verified - Updated -

Issue

  • When restoring thin-provisioned disks from backup, we are writing faster than RHV can extend the thin-provisioned disk. This causes the VM to continually pause.
  • How can we create a thin-provisioned disk with an initial size to receive the data from backup? (without continually auto-extending)?

Environment

  • Red Hat Virtualization 4.3
  • Backup solution (eg, Commvault)
