losing connection to ReadyNAS Duo

[zhenya]

I am running ReadyNAS DUO and lately started experiencing connection issues. All of sudden I can't access my shares from any system on the network. I am getting the following error.
---------------------------
Restoring Network Connections
---------------------------
An error occurred while reconnecting V: to
\\readynas\Data
Microsoft Windows Network: The local device name is already in use.
This connection has not been restored.

I still have access to the web management interface and Netgear reboot will solve the problem. Sometimes the fix stays for only few hours and sometimes it's good for days.

Any ideas of what's going on?

What is the current firmware version on your NAS?

Do you have a backup of all data stored in it?

Have you tried connecting your NAS directly to a PC and check if you will be able to access the shares?

[zhenya]

Firmware version is RAIDiator 4.1.14 [1.00a043]
I have a full backup of all data.
I haven't tried connecting directly to the PC. When I reboot the system I can access shares over the network. Connecting to the PC will not necessary indicate if the problem is fixed or if it's just a reboot that solved it.

Good to know that you have a full backup of data.

I suggest that you perform OS reinstall on your NAS and it might help. Check this link as reference guide: http://kb.netgear.com/app/answers/detail/a_id/24874

I believe this is a windows issue, not a NAS issue.

There is a hotfix for windows 7 here: http://support.microsoft.com/kb/2663418
This might also be relevant (depending on the Windows version) http://support.microsoft.com/kb/297684

Thanks. Unfortunately this is not it.
My computer is never in a sleep mode (desktop). When this happens the same behavior is observed on all computers on the network. I've been running Windows7 for years, but this problem only started couple of months ago.

Do you have ssh enabled on the duo? What add-ins are installed? Are you using DLNA?

Intermittent connection loss could be an early sign that the OS partition (not the data partition) is filling. That can be fixed.

Though if you don't have a full backup of the data, you should make one.

[zhenya]

Stephen,
I don't think I have SSH enabled. At least I can't find where it is.
Here are the Add-Ons installed: NAS Monitor, NTOP, PHP
ReadyDLNA is enabled

I have full backup of data. I am a backup maniac. I have at least three full copies with one of them in the cloud.

Good. One option is to simply factory reset. If it comes to that, the order is
(a) save your config file, and note your addons
(b) reset
(c) reinstall addons. Install viewtopic.php?p=392371#p392371 as well.
(d) restore the config file
(e) restore your data from backup

Make sure you do (c) and (d) in the specified order.


Or start by deleting your logs (system and backup). Don't attempt to download them.
Then install the sparc add-on here: viewtopic.php?p=392371#p392371 That will move your readydlna data off the OS partition and onto the C volume. Then it would be a good idea to reboot the NAS.

At that point you could wait and see if the problem disappears, or you could install EnableRootSSH from here - http://www.readynas.com/index.php?s=root+ssh

If you install enablerootssh, you will also need some software on the PC to let you use it. For Mac this can be be done with terminal. But for Windows you need something like putty installed. You can find it here: http://www.chiark.greenend.org.uk/~sgta ... nload.html Then let us know, and we can guide you through the steps to check the OS partition.

Stephen, thank you.
I decided to go with an easier route to start with. I deleted all the logs and installed Toggle DLNA plugin. I also enabled SSH and was able to connect to it from my machine.

Forgive me for a basic questions, but I don't see how to trigger the Toggle DLNA plugin. I don't see it in the list of installed plugins.

Thanks.

It is installed, there is nothing to configure. If you install it again, it switches the cache back to the OS partition (which you don't want). Netgear calls this kind of add-on a "toggle".

Now that you have ssh installed, try logging in with putty and entering

df -h /
df -i /

and let us know what it says.

[zhenya]

Got it. Thanks.

ReadyNAS:~# df -h /

Your OS partition is almost completely full. So you need to find which files are filling it.

Try

ls -l -h /
ls -l -h /var/logs

If /var/logs is not where the problem is, you can use the ls -l -h / command to find the biggest directory.

Then search that directory until you find where the problem is.

[zhenya]

Thank you Stephen. I found the offending file upnp-av.log was nearly 1.6Gb. Here is the new output. Hopefully this solves the problem. Thank you for your help.

ReadyNAS:/# df -h /
Filesystem Size Used Avail Use% Mounted on
/dev/hdc1 1.9G 410M 1.5G 21% /

ReadyNAS:/# df -i /

/dev/hdc1 256000 14708 241292 6% /

[StephenB]

Much better!

Hopefully that will resolve the connection problem.
