is base vmdk size is increasing?
is it a thin provision vmdk?
Yes vmdk size is increasing.
Yes it is thin provisioned.
Then its possible, I will try to explain by this esxample
-Windows OS use some space--> 10GB (copied some iso) now your space in c: reduce ,and thin provision disk has claimed that space(10 GB).
-Now you delete that 10 GB from C: , Windows will shows the free space, but thin provision will not unclaim that space.
For this in vSphere 5 thin provision space reclaim feature support ,but storage vendor must support this.
Hope this explain it,
I understand your example - this was the whole reason why I V2V the drive last night - to reclaim the space. As a result I had 170GB free showing last night in ESXi, now there is 159GB... - Nothing on the drive has been added/deleted/changed to accomodate for 11GB of space...
Could anything else cause this?
other than that i have no idea.
v2v claim space (new for me).
windows showed approx 150GB free... vmdk was showing as full in esxi.
- Installed Converter in VM
- Ran conversion of C:\ drive to new vm
- Moved newly created vmdk file to correct directory
- Removed existing VHD from VM config
- Added newly created VHD
Having the same issue.
Reclaim space from thin provisioned disks is complicated. If you have vSphere 6.5 consider to move to virtual hardware 13.
