Solved: Space reclaiming not possible: "there are no files on the VM that contain NTFS partitions"

BRECHTMON · ‎2013-04-10

Hello,

I installed VSC 4.1 on Server 2008 r2, used with vsphere client 5.1.0, ONTAP version 8.0.3.

For testing purposes I connected to the controller using netapp root credentials. I can see the controller just fine under "monitoring and host configuration"

I want to reclaim space on a virtual machine which is located on a NFS datastore. When I click "reclaim space" I get the following error:

"Error: there are no files on the VM that contain NTFS partitions". The partition is, in fact, NTFS.

What could be the issue? Thank you!

Ok, so the VAAI thing is a separate issue, but not seeing your controllers under the "Provisioning and Cloning" tab is probably related. I have one of two suggestions at this point. First, you can open a support case so we can get the logs and take a look. Second, if you want to try the hammer approach, you could restart the VSC service on the box and/or reboot the VSC box. I don't like suggesting the latter because you are not likely to figure out exactly what is wrong, but sometimes getting it working is all that matters...

Is the partition MBR or GPT?

BRECHTMON · ‎2013-04-10

MBR

Is the VM a template or a VM in the eyes of vCenter?

BRECHTMON · ‎2013-04-11

it's a standard run-of-the-mill vm. I think. I never used templates that I am aware of.

I guess it might not have to do with the VM but with a configuration problem or error.

I get the same error on VM's which are located on a controller for which I have not configured netapp credentials yet. Is controller access required to do space reclaiming?

The situation is the same for several sets of vsphere credentials, including root.

The "provisioning and cloning" tab shows "no controllers found", even though the controller is available under "monitoring and host configuration". Might have something to do with my space reclaming issues.

perhaps has something to do with this:

https://communities.netapp.com/thread/21105

We're running ONTAP 8.0.3 7-mode. Under "monitoring and host configuration" it says "VAAI Capable" but under datastore view hardware accelleration is "not supported".

Rebooting the VSC box fixed the issue and all seems to work fine now. Thank you for your suggestion.

Getting it working is indeed what matters to me... 🙂

glowe · ‎2013-04-11

Glad to hear. As for the VAAI issue - I realized that you are running 8.0.3 7-Mode. That version indeed does not support NFS VAAI. You need to be on at least 8.1.1 for 7-mode and have the NetApp NFS VAAI plugin installed on your hosts.

I just wanted to follow-up and say that while that is a "very good hammer" 🙂 we have identified the problem with controllers appearing in MnHC and not in PnC. That will be addressed in our upcoming VSC 4.2 release.

Hello Brecht Monkerhey ,

I have installed VSC 4.2 with Vmware ESXi 5 environment. I am able to reclaim space only for Windows VMs . It is not supporting any Linux VM till now. Is there any way to space reclaim using VSC 4.2 for Linux and other Unix VMs .

Also It will be great if you can provide me any information related to power shell module for VSC 4.2 . i could not find any module for VSC 4.2 which have space reclaim command in built with the module .

Thanks & regards

Saswat

brianjm · ‎2013-07-23

VSC 4.2 (and earlier versions) have always only supported space reclamation for NTFS partitions within Windows VMs.

SASWAT_MOHANTY · ‎2013-07-23

Is there any Power shell command for kamino module for space reclaim for Windows VMs ? I am looking from old Kamino module but there is no command available .

brianjm · ‎2013-07-23

I'm sorry, there is not. Space reclamation was never added to the Kamino API, and therefore, there is no PowerShell command to invoke it.
