Is there a way to see actual disk space used versus provisioned size in 3.5?

[RickSz]

Hi Folks,

I'm sure this has probably come up.

I need to find how much actual disk space is used by the VM as opposed to it's provisioned size. I have to make this point to management for upgrading to Vsphere 4 using thin provisioning.

Is there a script/app that might do this easily enough.

Regards,

Rick

RVTools is a great ESX Admin tools to have and it has a lot of features you can take advantage and datastore details is part of it too. Check it out great free tools

This did the trick!

Thanks so much!

I've just downloaded RVTools, and it gives me the Provisioned space for each VM, or the actual usage for each Datastore . . . . but I still cannot find the actual usage by VM?

Have I missed something?

check the vPartition tab.

I see. I think we may be talking about different things, though I now see this provides evidence for thin provisioning.

What I mean is that the total disc space used on the datastore for a particular VM will be its VHDs, plus swaps, plus snapshots, plus other overheads?? I should like to see the total of all of this for each VM. (I assume that snapshots, particularly, can use a lot of space on the datastore?)

Connect to your host using SSH of console and browse to your datastore "cd /vmfs/volumes/[DatastoreName] then run the command "du -h" .

du will summarize disk usage for each FILE, recursively for directorys.

-h = human readable

It isnt perfect but is is a good workaround.

Thanks Prost. That's great, and I'll see whether I can manage SSH etc. (I'm one of those lazy System Managers who like everything to be GUI!)

But it does look quite easy. I'll give it a go. Thanks gain,
