Question regarding reclaiming Nimble volume usage after VM Guest OS has permanently deleted
Hello,
Environment - ESXi 6.0 latest Update, 2012R2 Guest OS, Nimble CS300 w/ latest FW.
I have a 2012 R2 VM with a newly provisioned secondary virtual HDD, on a new VM datastore that sits on a new nimble volume.
Secondary Virtual HDD - 100GB
VM - Datastore 125GB
Nimble Volume - 125GB
Onto the question/issue
On the 2012 R2 box I loaded up the new HDD with 4.2GB of data, watched the usage grow inside of the nimble reporting then sometime after I peramnently deleted the data from within the Guest OS. I waited a few days, but the usage on the Nimble Volume was still showing 4.2GB. So the data was permanently deleted from the 2012 R2 VM, but the Nimble Volume is still showing that 4.2GB as usage. Is this a VMware issue or a Nimble issue? Do I have to look at the VMware Datastore for releasing these blocks?

If you'd like the VM to shrink is size you'd need to do a storage vmotion, if you'd like the VMFS datastore to free up deleted space to the nimble you'd need to issue a unmap command
VMFS 5 Cleanup -
esxcli storage vmfs unmap -l exact-datastore-name-here
Also, there's some great documentation on InfoSight for a better understanding

Re: Question regarding reclaiming Nimble volume usage after VM Guest OS has permanently deleted
My understanding is that only works if your virtual hdd's are allocated using thin provisioning from the datastore they're using. Mine use thick, so in VMware despite what data is on the GuestOS it reports 100GB of 125GB "in use" under the datastore in VMware. While Nimble shows 0GB of 125GB in use.

HI
I have created new VMFS6 volumes and moved data from vmfs5 volumes to vmfs6.
vmfs6 is now able reclaiming (UNMAP) datatstore automatically.
See this comparison table:

Hi,
There's some helpful info on requirements and behavior for in-guest unmap in the vSphere Storage Guide:
edit: fixed typo
