Network connection drops after a few hours.

[jholden]

My ReadyNAS Pro6 drops network connection every so often, it started happening after the last firmware update to RAIDiator 4.2.30. It works fine after I reboot it, then it drop all netwrok connectivity after a few hours untill it's manually restarted. I've read several other similar stories around the internet some claim Hardware issues, other Firmware.

Anyhow, my hardware is still under warranty, but is there any way to downgrade the firmware to test? I cannot find any offical download links.

Thanks,

Josh

4.2.28 is here: http://kb.netgear.com/30002/RAIDiator-x86-Version-4-2-28  I don't think 4.2.29 was ever released (it just stayed in beta forever).

Have you checked for a full OS partition?  You would need to enable ssh with the add-on in order to check.

I've tried that firmware and several lower, down to RAIDiator 4.2.27, all of them yeild the same results. I'm convinced it's a hardware issue since no other settings have changed in the configuration.

A filling OS partition can also create this symptom.  Though often that also causes the firmware downgrades to fail.  

But if you want to check for that, you can enable ssh and tell very easily if that's the problem.

you'd install the Enable Root SSH add-on from here: https://kb.netgear.com/24551/ReadyNAS-Add-ons-for-RAIDiator-4-2-x86?cid=wmt_netgear_organic

Then either install putty (windows) or use terminal (mac) to ssh into the NAS over the network.  User name is "root", password is the nas admin password.

Then enter

df . -h

df . -i

and report back on the results.

You do of course have two ethernet interfaces, so you could also try switching to the second one.

df . -h

/dev/md0 4.0G 499M 3.3G 13% /
df . -i

/dev/md0 65536 11231 54305 18% /

Thanks.  That rules out the OS partition.

If you download the log zip file, you'll see the ethernet statistics in network_settings.log.  Try downloading it now.

You could leave the ssh window open, and enter while true; do sleep 5; ifconfig eth0; done

That will display the network stats for the first ethernet port every 5 seconds.  When the system fails, you might see something informative in the display window.  You can cancel the loop by entering ctrl-c.
