Hi all,My device:Model: ReadyNAS NV+ v2 Firmware: RAIDiator 5.3.11I'm trying to test out NFS on my HTPC to see the difference between SMB, which for some reason keeps buffering movies in XBMC/KODI when using Winodws.Anyway the issue is that I cannot access NFS shares properly, only the top level folders are visible, and cannot go deeper into the folders to actually play the files.I tried manually imputing the paths to specific folders, but that refuses connection.Now one surprising thing is if in the if I go to ReadyNAS web interface and go to Configure>System and then under Services, the place where you can toggle sharing protocols if I select NFS and modify "Number of NFS Threads:" option by either decreasing or increasing the value, and "Apply" it the shares are fully accessible for 60 seconds through XBMC. So I can go into the folders, start a movie, watch it for a few moments and then access is lost again.I've already researched a bit and attempted modifying the NFS shares parameters in /etc/exports/ by some advise found on different forums but that have not resolved the issue.Also tried resetting permissions and modifying write, read access, groups, users and hosts access (everything through ReadyNAS web interface) without any success.Any idea what could this be and how to fix it?I'm not a Linux expert, but I do have ssh access and I'm wiling to try some things if you can give me clear instructions :DThanks for help!

What are you using a separate volume for each disk? You have no redundancy, so if a disk fails all the data on that disk is lost.

Can you send your logs (see the Sending Logs link in my sig)?

Hi mdgm,

Separate drives are done on purpose, I don't really care about the redundancy, just disk space. Everything that is really important is backed up to a different device, and this one is used only for media streaming.

Sure, I will send you link to the logs via PM.

Thanks for your answer!

I don't have a back up of everything there. Just few things that are really important, but I would prefer not to factory reset it :)

Regarding restarting, yes, I did try it.
Tried disabling and re enabling all sharing protocols and disabling them.
Tried creating new shares (acting the same way as the old ones).
Tried adjusting the /etc/exports/ by adding async parameter to the NFS shares.

I remember NFS shares working in the past, probably over a year ago. There were some firmware update since then, but can't remember any more changes.

It looks to me like backing up the data and doing a factory reset (wipes all data, settings, everything) would be the best way forward for your problem.

Well, that's not really an option as I don't have any place to put 10TB of data :) any other ideas?

Does it fail on all volumes?

Yes, all the NFS shares act the same on all volumes. So if I disable NFS and re-enable or change the number of NFS threads all NFS shares will be accessible for 60 seconds with all sub folders accessible and then after 60 seconds I'm loosing access. only the top folders can be seen but I can;t get deeper into the folders and files.
