Clone / Storage vMotion Fails: cannot access *.vmdk

[markusk1985]

Enviroment:

- vCenter 5.1

- ESXi 5.1

(both latest Build)

- NetApp NFS Sotorage

- NetApp VAAI NAS Plugin 1.8

Problem:

If i try a Clone by vCenter i get the Error "Failed to access *.vmdk" (see Attatchement)

If I try to Clone the VM by vmkfstools:

/vmfs/volumes/ec4e3e51-985cfc6d/TPLW2K8R2DCE_MSDN # vmkfstools -v 9 -i /vmfs/volumes/netapp-07_w2k8_000/TPLW2K8R2DCE_MSDN/TPLW2K8R2DCE_MSDN.vmdk /vmfs/volu

Any Ideas?

Hi,

I think the vmkernel multiextent module is not enable .

Can you check with this  : esxcli system module list | grep multiextent

If not , for enable the module : esxcli system module load -m multiextent

Regards,

Julien

HI,

multiextent is running:

/var/log # esxcli system module list | grep multiextent

multiextent                         true        true

Ok,

Did you try from an other host?

And can you try this command plz :

vmkfstools -i original.vmdk -d thin ../newmachine/copy.vmdk

Regards,

Julien.

Hi,

yes I tried the clone from an other Host with same build. Its the same problem.

I tried to specify "-d thin" and "-d zeroedthick", its the same result.

[julienvarela]

Can you attach the hostd.log file and vmware.log.

Thank you.

Regards,

Julien

[markusk1985]

there is no log output in vmkernel.log or hostd.log when this happens.

[julienvarela]

and in vmware.log not vmkernel.log ?

Regards,

Julien

[markusk1985]

Oh, sorry.

Its the same... no output.

I found three different articles describing something like what u face:

1-)The One that mentions Julien's solution.http://blog.acsystem.sk/linux/migrating-esx-thick-disk-to-thin-disk-esx-5-1-is-always-special

2-) virtuallyGhetto: 2gbsparse Disk Format No Longer Working On ESXi 5.1

3-) VM Communities

For number 1 read it again carefully specially he clones on two stages: from original disk to 2gb disks then to the new disk (Used if u converting from thick disk to thin one)..

Wish that I can help with one of these...

[markusk1985]

Hi ShadyMalatawey

I am familiar with these posts.

But, no one of these solve my problem...

The problem affects all of my VMs on different datastoes (all NFS) and Hosts.

[julienvarela]

It is really strange that you have nothing on your log because we see an event on your vcenter.

So for more investigation, we need your logs. vmware.log hostd and vpxd.

Thank you for this.

Regards,

Julien.

OK,

it seems to be  problem with NetApp VAAI NAS Plugin.

I opened there a community Post:
