Troubleshooting NetGear ReadyNAS Problems

Recently I wrote about having severe problems with the NetGear ReadyNAS. These problems were causing the device to fall off the network requiring a hard re-boot to make it available on the network again.

The hard reboot was bad enough but the subsequent media check meant the reboot time would stretch into hours before service was restored. Not exactly the kind of customer experience I was hoping for when I bought the device.

Things were getting so bad that I began researching a replacement device that I could purchase to replace the NetGear ReadyNAS. In the ReadyNAS Pro I have six 1.5 TB drives configured as a RAID 5 enclosure. That gives me 7.5TB of online storage.

I have been diligent in updating the firmware on the device and give it regular cleanings with compressed air so as far as I was concerned I was being diligent in managing the device. Despite my best efforts, the device continued to cause me problems.

After yet another hard re-boot my frustration level had reached new heights. I had about reached the end of my troubleshooting patience when for some reason I decided to change the configuration.

Up to this point I had configured the ReadyNAS Pro with two gigabit Ethernet connections directly to a Cisco switch. I seemed to remember that I added the second Ethernet connection just recently. I wondered if perhaps I had a bad cable.

I removed one gigabit connection and waited. After two weeks I did not have a single drop off by the device. I wondered if perhaps I had a bad cable. I swapped Ethernet cables and again left the device to run.

Another two weeks went by with no issues with the ReadyNAS device. It did not appear that the problem was cable since I had used two different cables. I decided to see if the problem was connecting both Ethernet ports. I plugged both cables into the device and restarted the ReadyNAS.

Within two hours the problem appeared and the device disconnected itself from the network requiring a hard boot. After several hours rebuilding and checking the drives the ReadyNAS was back on line.

This time I am using just a single Ethernet port on the ReadyNAS device. While I might theoretically only be getting half the throughput in this configuration it is a lot more stable and that is better than raw speed any day of the week.

    It is my understanding the two ethernet ports *do not* provide the ability to double the throughput, they are for physically connecting the RNas to tow *different* networks. Connecting them to the same network or subnet can cause the problems you have experienced. I have two RNas+ 4000s, each connected on only a single Enet port.
