We are implementing Storage DRS for a two host vSphere 5 (HP Image 5.0.0 623860). This is connecting to a P2000 FC MSA. To conserve space we were considering thin-provisoning the OS C: vmdks. Research indicates there may be issues with space reclaimation. Are there any present issues with VMWare reclaiming space on thin VMs? Will DRS move the vms properly if they are thin and reclaim the space that was being used? Are there any pitfalls to be aware of (besides monitoring the space and setting alarms)?
Many thanks in advance for any assistance.
