Using vmkfstools to reclaim VMFS deleted blocks on thin-provisioned LUNs (2014849)

Hi, all

I have a question regarding KB 2014849.

http://kb.vmware.com/selfservice/search.do?cmd=displayKC&docType=kc&docTypeID=DT_KB_1_1&externalId=2014849

I have ran "vmkfstools -y 60" command, but did not increase free space.

I suspect the command has NOT reached to storage.

How can I confirm the command has reached to storage? vmkernel.log or other logs?

In other words, how can I confirm the storage has received the command?

Best regards,

Taro
