Western Digital WED EX2 NFS
« on: May 25, 2015, 01:53:55 pm »
Hi all,
I have recently purchased a WD EX2 and insalled 2 x HDD's and now 2 x external USB3.0 HDD's as well. I have enabled NFS in the EX2 and can stream to the X3D and other DLNA devices on the network, however for some reason I cannot stream 2 HD rips at the same time on my network - one of them always goes choppy - and I thought I would be able to do this as I have an all Gigabit network (supposedly!). NFS is set to on in the EX2 & the X3D (Samba on the X3D is turned off - Is that right?) and when I use the X3D to probe the NFS mounts on the EX2 it correctly shows the 3 shares I have set up. However if I then try to go into the shares the X3D completely locks up and the only thing I can do is to unplug it and restart the device. If I manually add an NFS share and hit enter the X3D comes back and says Failed. The shares are Write enabled.

Any thoughts please? I hope it is something simple!

What setting are you using for mtu size on your NAS?
Is it set to use default mtu size 1500 and not uising a higher mtu size?

I get the same problem if the NFS host drive on my PC has spun down.   So what power management on the drives are you using?

Thanks for the replies, I cannot see MTU in the settings, is it the same sort of thing as Jumbo Frames? If so then that is set for (OFF) 1500 in the settings and the Drive Sleep is set to Off.

The USB enclosures could have their own logic for spinning down the drive. Have you merged all the drives into a huge virtual drive?  I was hoping you hadnt so that you could test a share only on internal drives.

Hi, I have the 2 internal drives set as one volume (RAID 0) and the 2 external USB3.0 drives as individual drives.
All 3 of the NFS links come back as Failed in the X3D when added by NFS mount point line, and all 3 crash the X3D when added by NFS Probe.
 
Good point about the power down on each of the drives, I am not sure whether there are settings for each drive, the only setting I can find is in the EX2 called Energy Saver and I have now set that to Off. The 2 external drives are: 1 x WD 2TB USB3.0 My Cloud and the other is an internal WD RED 2TB drive in an external USB3.0 enclosure.

What about the power saving in the X3D?

Are there any settings in the X3D I should try? Auto/TCP/UDP etc?

So as yet you have no working links?  I thought you had, and the crashes come from using them?  Not making links , indeed auto NFS probe  nor finding them for you, indicates a networking issue, probably DNS.

Yes, jumbo frames should be off. Then you get mtu 1500 which is the correct setting to use with the Mede8er.

Set your Mede8er to TCP.
Remove all manual made NFS points.
Then restart your mede8er to give it a clean start.
Now try again a NFS probe under Mede8er NFS.
If you dont see shares coming, reboot your mede8er again.
Now again goto NFS menu, do you get the NFS shares you created on your NAS?

Wow you guys are awesome. It works, now I am not sure why but this is what I did.

Deleted the existing NFS links that I knew wouldn't work.
Changed to TCP in network settings.
Shut down system and removed mains plug
Plugged it back in and the NFS shares all appeared straight away and all 3 of them now work.

Success  ;D

Now to try to sort out the issue with running 2 HD rips at the same time, I think I will download some of the Jellyfish files and see what happens and when.

Thanks once again for your help.

A WED EX2 is not a very powerfull NAS from what I have seen.
I also saw by googling on reviews that the NFS streaming peformance is a lot better then samba read peformance.
So you might see better performance now.

You also might want to try to set your mede8er to a higher rsize under nfs settings, set it to 32k and see if that gives better streaming results. Big question is if our NAS supports that rsize, could not find anything about that.
Be sure to reboot your mede8er first after changing this setting.

Thanks will give the 32K a go as I have checked the firmware revision updates and can see that they introduced support for it last year:

Firmware Version 1.05.21 - (10/27/2014):
Upgrade to the My Cloud OS 1.5 experience
Resolved Issues:
