Potential issue on NFS server, RT-AC68U

[matthew_eli]

Hi all,

I encountered a problem I've not faced before with RT-N66U about the built-in NFS server; using NFS server in RT-AC68U and setting it like I had in RT-N66U, results in no NFS server at the router boot. Let me explain better; I use NFS for mounting the Hard Disk on USB and then reading it by my WDTV Live over ethernet. When I had Rt-N66U I set the NFS as in the following image:



and all works flawlessly, since from the router boot. Instead, with my new RT-AC68U, .38_1 firmware by Merlin, using the same settings, I need to manually turn off and on the NFS exports or simply changing any settings of it for having the export mount seen by my WDTV. Most probably using the WDTV is not the best way to debug if the NFS exports are working normally and thus I would ask you a way for testing it effectively.

I enclose in the following what log reports for the NFS:

When I change the settings and the service starts correctly (at least it is accessible by WDTV):

Jan 13 09:20:03 kernel: svc: failed to register lockdv1 RPC service (errno 97).

When the service starts at boot (there are 2 differents date, but it's for the NTP read, it happens all in few seconds):

Could you help me in figuring this problem out?

 

[matthew_eli]

No one facing thw same problem? Do you know a tool for debugging NFS on Windows 8.1?

 

[L&LD]

Try to be a little more patient and let people who can answer either wake up or finish work first...

 

[matthew_eli]

You're right. I'll be...

 

[L&LD]

Ty. Try to give at least 24 hrs before you bump a thread.

 

[matthew_eli]

After several tests, I can confirm I have the same issue described in this thread:

[AndreaS]

Me too, I'm having the same problem, but I reported it in the .378 build thread.

I have the same issue on the AC68U - on the N66U it works like a charm!

With kind regards

Anyone get it working. I am still not able to get it work with even with latest firmware 376.47

 

[joegreat]

Hi,

Recent test on RT-AC68U show that the issue still exists in the firmware (Merlin build 376.48_1) - see log below.

Did anyone try to get NFS working with Entware/Optware?
Would need some tweaking to get firmware round the build in NFS and portmapper...

With kind regards
Joe
