Hey, hoping someone can point me in the right direction.
I recently took over an ESXi instance, and have run into space issues on the box.
Physical Server: HP Proliant DL380p Gen 8
OS: ESXi 6.5 U2 Sept 2018 – Last Pre-Gen9 custom image
License: VMware vSphere 6 Enterprise Plus
I have a datastore, which is 2.73TB in size, and is VMFS5. Thin Provisioning is supported.
All the VM's are Thin Provisioned, but ESXi is not reclaiming space from deleted VM's, deleted files on the VM's, or deleted Snapshots.
Checking the disk information:

And i've checked the related configurations in esxi
| Key | Name | Value | Default | Overridden |
|---|
DataMover.HardwareAcceleratedInit | Enable hardware accelerated VMFS data initialization (requires compliant hardware) | 1 | 1 | No |
DataMover.HardwareAcceleratedMove | Enable hardware accelerated VMFS data movement (requires compliant hardware) | 1 | 1 | No |
DataMover.MaxHeapSize | Maximum size of the heap in MB used for data movement | 64 | 64 | No |
VMFS3.HardwareAcceleratedLocking | Enable hardware accelerated VMFS locking (requires compliant hardware). Please see http://kb.vmware.com/kb/2094604 before disabling this option | 1 | 1 | No |
Trying the manual unmap also doesn't work
[root@esxi01:~] vmkfstools -y /vmfs/volumes/datastore2/
Volume '/vmfs/volumes/datastore2/' spans device 'naa.600508b1001caf2ad46535555b3e0206:1' that does not support unmap.
Devices backing volume /vmfs/volumes/datastore2/ do not support UNMAP.
So really I'm at a loss on where the problem is. Is it the physical disks, or the LUN.
Is there any way to enable this unmap command without having to rebuild the entire datastore?
Can anyone point me in the right direction?
Thanks!
