Timeout when creating qcow on NFS storage

[JustaGuy]

I have an NFS share from a Windows box on my PVE box, currently with backups & iso's. Today I tried to add an export to add virtual disk functionality over NFS. I can create RAW disks fine, but if I try to create a .qcow, it times out each & every time, no matter what I do. The network isn't saturated, but it's not gigabit either. See attachment for error screenshot.

Here's the relevant storage.cfg entry with the options I tried to no avail.

nfs: disks
    path /mnt/pve/disks
    server x.x.x.x
    export /disk
    options vers=3,timeo=7200,retrans=9999
    content images
    maxfiles 1

I'd like to be able to use snapshots, so if someone could let me know how to make this work, I'd appreciate it.

I think it must be a bug or missing feature in nfs implementation in windows.

I never see this kind a problem with linux nfs server or commercial storage (netapp,..)

I'm using HaneWin NFS server

Why not use the native Windows NFS server?

 

[JustaGuy]

That would be ideal, but I don't think it's an option for my OS (Windows 7 Ultimate).

When I open nfsmgmt.msc, it looks like there's only a client available. See screenshot.

OK. I thought you were running a Windows Server.
You could try this approach for running a Linux NFS server on windows using cygwin: http://www.morethantechnical.com/2014/01/08/share-nfs-from-windows/

Before I opted for the non-free HaneWin NFS server, I did try that cygwin method. I don't remember exactly how, but it failed to work properly, or maybe it didn't install right- either way it didn't work.

I guess I'll just settle for .raw disk images for now.

Thanks nevertheless for your input.
