Greetings!
I have a few questions for you guys. I have been studying how the reclamation of deleted blocks occurs on a given datastore. While I get the commands to do this ("vmkfstools -y" in 5.0/5.1 and "esxcli storage vmfs unmap" in 5.5), I need clarification on what is actually happening.
1. If the datastore is 600GB and shows 100GB free in vSphere, is the full 600GB shown as allocated on the SAN?
2. We are running vSphere 5.1. If I run "vmkfstools -y 50" to reclaim 50% of free space, what happens to the SAN?
3. Does the reclamation only affect deleted blocks, or does it affect all free space?
That's all I can think of for now. Thanks!
