    vmfs unmap command

      Hi

      esxi 5.5. Thin Provision

      I have delete a lot of guest os files.

      VMDK file is still big.

      I understand i need to run esxcli storage vmfs unmap command in order to unmap the deleted blocks.

      What will happen then? the VMDK will be smaller, so the SAN (EMC) will also reclaim it's space?

      What would happen if i won't run it? does the dead block will be re-used by the SAN ? Or should the LUN will consume more space?
