Impossible to Create Qcow2 disks on NFS storage

[toxic64]

Hi all,

I have a strange problem here.

I have a clustered proxmox VE 3.1 connecting to WINDOWS 2K8 R2 NFS Server.

I mounted two NFS shares on proxmox storage tab and I can see them and use them.

Only thing is that when I create a VM (KVM) it will only work with a VMDK disk.

When I try with Qcow disks, I get this error

"TASK ERROR: create failed - unable to create image: got lock timeout - aborting command"

I did not test RAW yet.

Also I tried creating CT and it fails too...

I have searched the web for similar problems and found one thread only that seems to have been abandoned.

Anyone has an Idea about what is going on and how I could troubleshoot it?

Thanks a lot for your help.

Does windows nfs support sparse images?

Well, I don't know what you mean with that exactly but I don't see why not although it seems indeed it's totally NFS related as Qcow2 VM's work fine on the local storage. (which I can't use actually...)

Most modern file systems support sparse files, including most Unix variants and NTFS

if this is the right thing I have found it seems so.. assume the NFS storage is running over NTFS or am i wrong?
