Issues since 6.4.0 upgrade on RN10400

[Barok]

Hi.

I'm french, so be comprehensive with my english.

I upgrade my RN 10400 2 weeks ago from 6.3.2 (I think) to 6.4.0

The NAS as my 2 computers are connected to a gigabit router with category 6 cable.

Since the upgrade, i have problem to stay connected.

Ex :

-> I have lot of deconnection to the admin panel, +/- every 2 minutes. Sometime it take 5 minutes to get a new access to admin panel.

-> It's impossible to watch movies from the nas. In VLC, I increase the video cache from 1.5s to 30s but i have the same deconnection problem and the video stop. This happen, every 2/3 minutes.

-> When i want to access to the files via windows explorer (all my volume are mount as a network drive in windows), i need to take a while (20/30s compare to 1/2s before)

-> When i copy files from nas to my computer the transfer rate is around 50Mo/s (not problem with this) but after a while, it decrease to 0 for about 2 minutes then back to 50

I can't get back to 6.3.2 since the NAS does not allow it.

I try 2 beta of 6.4.0 firmware but I have the same problem.

Is there any solution ?

Same file that took 30mins now within 2 secs at 110Mb/s

I know whare to look now, I'll start reading about Win10 name resolution. Still strange that it happened after the readynas 6.4.0 update.

Thanks a lot

You could try disabling IPv6.  Perhaps Windows 10 is resolving the hostname to the IPv6 address, and a device on your network is unhappy with that.

I have the exact same problem, so I hope there'll an answer to this.

[Barok]

Happy to see I'm not alone. Hope netgear will deploy a new firmware to correct this.

is there any solution to get back to an old firmware version.

I upgraded to 6.4.0 and now my RN 2120 is so slow that it is completely unusable. I removed all the apps and the antivirus it is just a file server at the moment but it stays incredibly slow. This nas has been working fine for more than a year. Is there a way to go back to the previous version without wiping all my files? 

Just copying a smal file takes ages and I can't even play an audio file from the RN2120.

Is this an offical release? What can i do ?

How long ago did you upgrade it?  btrfs-cleaner can take quite a while to finish up after the you reboot.  Initially it hogs the CPU and slows the system down.  It should eventually finish though.

Hello Sijmen,

Welcome to the community!

It is an official released. It is not possible to downgrade the firmware. However, you can try contacting support to get this done by L3 support.

Thank you is there a way to see if this btfrs cleaner is busy? Would be nice to have some sort of task manager to see what is happening on the server.

[Sijmen]

I upgraded 2 days ago. And my server powers down during the night. So it had more than 14 hours since. Could this btfrs process take longer?  I have 4 disks of 4 Tb in Raid 5

Hello Sijmen,

Please see BTRFS info on the bottom part of the article at: http://kb.netgear.com/app/answers/detail/a_id/29961

Thank you Jenn,

I have read it, upgraded to 6.4.1-T21 and made sure that my 2120 doesn't power off tonight. I'll have a look tomorrow morning if things are back to normal speeds again.

Cheers, Sijmen

Now I am running 6.4.1-T21 and the RN2120 has been on for 36 hours but it is only getting worse. But I found something really strange I tried copying a 200Mb file to my windows 10 pc, the file manager froze a few times and when I could finally select the file and copy it. This took about an hour, the speed was constanly going up and down. Tried it on another PC (also windows 10) and the same thing very patchy and slow connection and it took more than 45 minutes.

I stopped all services except for http, https and SMB, removed all apps, deleted all the shares I don't use (5 left)

All to no avail still unusable slow

Checked the logs, nothing out of the ordinary.

But now the revelation: I copied the 200Mb file via wifi to my macbook (connecting via SMB) and it copied in 2 minutes.

Quickly booted up an old windows 8.1 pc and tried it there, same file was copied within 10 seconds. Wow thats what I want to see.

So it has something todo with how my Windows 10 pc's access the readynas server. Any suggestions?

[Skywalker]

It doesn't appear to be a generic issue.  I'm able to copy files from my Win10 machine to a RN2120 at >90MB/sec.  How are you accessing the NAS?  By hostname, IP address, mapped drive, ReadyCloud, etc?

[Sijmen]

I agree that it seems like a Windows 10 issue but it only started after upgrading my Readynas to 6.4.0

I access as follows: In the windows file manager the readynas server appears with its name (SanJose) under network. When I open it, I see all the shares on the server like videos, music etc. The path I browse to would be like \\SANJOSE\Videos, then I take a video file of around 200Mb and that takes 30 minutes to copy while with the exact same method on Windows 8.1 it is less than 10 seconds.

I was assuming that was accessing with the SMB protocol.

My network is a private network 192.168. etc and the one who gives out the adresses is the dhcp service of my pfsense firewall. My readynas RN2120 server gets two reserved addresses so those will always be the same. 

On the RN2120 i only have SMB, HTTP and HTTPS running everything else is off. No apps, No readycloud. During my copying of a testfile to a windows 10 Pc I am looking at the speed and it is very patchy up and down but a speed that I see alot is 355Kb/s.

Thanks for trying to help

[Skywalker]

You may want to try accessing by IP address (eg. \\192.168.1.2\Videos), to rule out any weird name resolution issues.  Windows 10 had some bugs in that area at launch, and I'm not sure if they have been resolved in any public updates yet.

[Sijmen]

Thank you Skywalker very good advice.

Same file that took 30mins now within 2 secs at 110Mb/s

I know whare to look now, I'll start reading about Win10 name resolution. Still strange that it happened after the readynas 6.4.0 update.

Thanks a lot

[Barok]

Agree it works for you but I still have the same problem. Everything is very slow. It's almost impossible to access to web admin because I'm diconnected all the time, connected with DNS or IP (192.168....)

Is there any firmware upgrade planned in the next days/weeks because the NAS is clearly unusable.

EDIT : I just upgrade to 6.4.1T21, same problem

Hello Barok,

Can you try changing MTU to 1500? If it's already 1500, change it to 9000 then save then change it back to 1500. See if there is any improvement.

Regards,

[Barok]

Thanks for your help.

It take a while because I have lot of disconnection in the nas admin. I change the MTU from 1500 to 9000 and 1500 back, same problem, no improvement.

Regards

[JennC]

Hello Barok,

Maybe it's best to contact support if that is the case then.

[Sijmen]

Hi Barok,

No it still doesn't resolve the names properly even after flushing my DNS but I can work around it now by using an ip addres. It sounds like you have a different problem because I never had any problem accessing the admin page of the readynas in a browser. It was just my file access in the windows file manager that was/is the problem.

I sympathise, this kind of thing is a very frustrating search.

Since readynas is just a flavour of Linux i am surprised that there is not something like a task manager or process monitor to just have a look what is running on the server and what not.

Good luck,

Sijmen

[Sijmen]

Yep you were right I disabled IPv6 on the network adapter properties and it works fine now >110Mb/s

Thank you very much Skywalker.

[Barok]

Me too !!!!

I disabled IPV6 on my router/nas/network adaptater and all is fine now.

Thank you very much but .... this happen since 6.4.0 so I think the firmware has an issue.

[Sijmen]

Hi Barok,

Yes it looks like it happened with the readynas 6.4 upgrade but while googling around I did find a lot of people who had trouble with windows 10 DNS resolving after a windows update of around 14 October 2015. So I am not sure anymore, it might be a combination of microsoft and other suppliers not agreeing on how Ipv6 should be implemented.

If you have like me an internal private ip4 network, I don't think you need Ipv6 anyway.

Cheers, Sijmen
