Showing wrong disk type?

Jump to solution

I did the following and wondering why it still saus thin:

1. created a thin disk via gui

2. I ran vmkfstools -i file.vmdk -d zeroedthick file1.vmdk

3. Removed file.vmdk from vm

4. Added file1.vmdk to vm ( during adding the vmdk it said it was thick)

5. Now in edit settings the new drive says thin disk even though i know its thick.

Is this default, or a bug?

Thanks

William

I performed the exact process you mentioned in your post and did not experience the issue you stated. When I attached the new VMDK it reported as thick during the add. I clicked OK to the "edit settings" dialog which committed the VMDK add. I checked back in "edit settings" and it still reported as thick. I then proceeded to boot the test VM and check the setting again--still thick. I am running fully patched ESX and vCenter.

I forgot to mention that this running on esxi 4 and using NFS off of Netapp.

Would that make a difference?

I think NFS VMDks are always thin regardless of the setting you use in the GUI.

Hmm So a default setting (which I presume we cannot change) is all vmdks are considered thin over NFS? Even if they are considered thick?
