Does RHEV support sending TRIM / discard / SCSI UNMAP commands to attached storage?

Solution Verified - Updated -

Issue

  • My storage supports thin provisioned LUNs.
  • Will RHV send TRIM / discard / SCSI UNMAP commands to the storage when blocks are freed so the storage array can release those blocks?

Environment

  • Red Hat Virtualization 4
  • Storage with support for thin provisioning.
