Used / Free spaced disparity between Guest OS and Datastore Info?

[captainmarvel]

Hello!

I am having an issue that is stumping me. I currently have a handful of VM's that are using a high amount of disk space (well, high for these VMs).  For example: VMware is reporting used space at close to 2TB.

However, the guest(s) (server 2012, and server 2008) is showing appx 700MB.

The VMs reside across Virtual Disks all on the same LUN, Datastore, and folder structure.

The VM has up to date VM tools

I have run spacesniffer on the VM, and it didnt find any crazy files that was sucking the disk space

I checked for restore points

I am also having the same problem with a couple Server 2008 VM's as well.

Very confusing.

Any guidance would be appreciated!!

Thanks

Hi CM,

Could you give us any more information.  You say "Vmware is reporting used space" where in the vi/web client are you seeing that? can you post up a screenshot? Are there any snapshots on the VMs (even ones only visible in the datastore not in the snapshot manager)?

Or are you saying you thin provisioned a 2TB disk to the VM whereas Windows is only showing 700Mb used (Do you mean 700gb?)

If you've defragged or run any similar process or even copied a large file to the vm and then removed it then the VM disk usage will remain at it's maximum.
