Readynas NV+ errors (LED lights) and how I fixed it.

Usually the Readynas is good at letting you know when something is failing...I didn't catch it this time.

I have two of these, one has documents and photos in a RAID5 configuration (you give up about a drive worth of data for redundancy...lose one drive and it will rebuild the data).  Of course a RAID is not a good backup, so I have a USB drive plugged into it that takes a backup of the RAID, and the most important things are also backed up to the cloud.

The second Readynas NV+ is set up in their RAID-X configuration, which is sort of like a RAID5 but you can add drives to increase the size.  I use that one for media, audio and video,

Both NASs are plugged into a UPS, but only one is connected electronically to the UPS to get autoshutdown the second one, when the power was out for a long time, was basically unplugged.

When I went to power them up, the first one booted up fine, the media one did not.

The problem...

The biggest issue with this smart NAS is unless it boots up completely, you have to guess what is wrong.

So the second one booted up with the LCD dark and blank, the LEDs for Drive 1 and 3 on...and nothing else...great.

Looking it up, those LEDs indicate the RAM is bad...I had put a 1gig ram into it replacing a 512meg one...I pulled the 1gig ram and put in the 512m when I try to boot it said something about OS not found...

...great...more googling later and I find that I need to do a USB OS install...You download the USB OS install firmware from Netgear (you have to know what version etc...luckily I knew I had the latest...see previous post about these drives).

I put the stuff on the USB thumb drive, put it in the slot and boot (instructions at Netgear, or here)

It get going along installing...and stops at drive 3...just kind of error message, but Drive 3 LED is flashing.  Drive 1 and 2 are on steady.

At this point I assume that drive 3 is I put a spare drive in (I keep a qualified, unused spare drive in case I get a drive failure like this...usually I can keep using the old drive somewhere else)

I try again with brand new -virgin out of the sealed antistatic bag- drive...I get the same exact result.

Well luckily they still sell the RAM, so I got on Amazon and ordered a replacement (using the part number off the 1gig ram I pulled.   Meanwhile I ran a ram test using the NAS (it has some self test capability even when it won't boot)  512M ram was bad also apparently....great

New ram comes a week later...I pop it in, do the USB OS install...this time that is successful, so I go for a boot...LCD says "Booting..." Drives 1,2,4 are on steady, drive 3 is flashing.

Remember that I have the new virgin drive in the #3 slot...ok I put the old drive back change.

Now after another few hours of googling, I find that I now need to do an OS reinstall...I did a USB OS install, but that only get loaded to the NAS...I guess the OS Reinstall moved the OS from the NAS to the drives themselves...or something like that.

Success!   Now it boots properly, LCD shows the drive info and IP address.   I go to log in using the web console...won't log in...bad password...great.

So apparently when you do these type of USB OS installs or maybe the OS reinstall, the login goes back to default...well for the older OSs it is admin/infrant1   ... the newer ones use admin/netgear1  ... other new versions use admin/password.    So I tried them all, but mine had defaulted to  admin/netgear1

Now I can finally view what the heck is going on...meanwhile while I was trying to figure out the password, I ran the RAIDar.exe  (a piece of software from Netgear that allows initial admin of NAS before they are set up)  It showed the problem NAS and said that drive 3 was bad.

So I was right, the #3 drive was bad...but why didn't putting in the new drive fix that?

My guess is that the last status of the system was that drive#3 was bad, and it kept that status stored on the RAID until the RAID gets fixed with a new synced drive...the light will flash.

So right now the NAS has resynced about 26% of the data...only 7 hours to go until the RAID is rebuilt and again redundant.

Now I need to see why the 8TB usb drive I plugged in to it is not registering....

...a day later...

I still haven't gotten the 8TB usb drive to register properly on the Readynas...I plugged it into an Ubuntu system and used Gparted to take a look...there is a small windows partition at the front of the drive...probably for use as a live recovery drive or I removed that partition and I am reformatting the entire drive...10% complete after most of a day.

So while waiting for that to go, I put my eSATA Raid as a network share and pointed the Readynas at it to do a backup...soon after the backup started it quit with a bunch of errors.

 (something along the lines of "cannot allocate memory" for each file failure)

...this was the solution for me...
