RND4210 v1 wont power on

Hello-

 

I had a power issue in my home and now my readynas no longer powers on. I swapped out the PSU with a ATX PSU from another computer ( I do not have a spare for the readynas ) and it will still no longer power on. I know this is a very old device. If I purchase a newer model as a replacement can I put my drives in it without issue? I remember reading somewhere that due to the CPU in this device, drives from it put into a newer device will not see the existing data.

 

If you could let me know what my options are here, I'd appreciate it.

Thank you.

Re: RND4210 v1 wont power on

I do see a guide that says its possible:

 

https://kb.netgear.com/29876/ReadyNAS-Migrating-disks-from-RAIDiator-4-1-or-RAIDiator-5-3-to-ReadyNA...

 

or 

 

https://kb.netgear.com/29957/ReadyNAS-Migrating-disks-from-RAIDiator-4-2-to-ReadyNAS-OS-6-x86

 

I'm not sure which version of the 4.x software my device has though.  I would assume the 4.1x

Re: RND4210 v1 wont power on

If you actually have an NV+ v1, then it should be running 4.1.x firmware.  An NV+ v2 would be running 5.3.x.  An ultra or a pro would be running 4.2.x firmware. 

 

There should be a sticker on the back which shows you the firmware that was installed at the factory.  You can post back with that information along with the full part number on the back, and we can confirm what platform you have.

 

As the KB article says, with support's assistance you can mount your data volume temporarily in a new OS 6 NAS.  You'll then have to off-load the data to backup, do a factory reset/system setup, and then restore the data from your backup.  They might charge for that, and if the failure caused any corruption of the file system you might need their data recovery service.

Re: RND4210 v1 wont power on

Hi Stephen-

 

It's definitely a version 1.  The back says FW 4.1.6.  The full part number is RND4000 v3 which is below the firmware sticker.  There is another part number on the bottom of the PSU that says RND4210-100NAS.  Either way though it looks like it's a 4.1.x.  I picked up a 214 with empty drive bays and will be calling support later today.  I had a little bit of trouble finding the right model on the website.  I'm not sure how old the 214 is compared to other models but it seems like it'll do the job.

Yes, that is certainly a v1.

It was announced in the fall of 2015.  The 200 series is intended for home users, and uses an ARM processor.   It's a lot faster than your v1 (perhaps 5x faster).

Re: RND4210 v1 wont power on

Hi Stephen-

It's only really used for my home VMware lab, backups, and my plex repo.  Sounds like that will be sufficient.

 

I'll post back with the results.

 

Thanks.

Re: RND4210 v1 wont power on

Hi Stephen-

 

I'm waiting for a call back from Level 3.  They charged me the $200.  I also asked them about being able to move these 4 drives and add two more to a 316 ( as an alternative to having to purchase 4 new drives to upgrade space ).  They told me that they are different achitectures and I'd have to backup everything, blow away the 4 drives and add the 2 new ones, and then move it all back.  Is this correct?

They mount the NV+ disk temporarily in the new NAS so you can offload the data to backup.  Then you need to do a fresh install, set up the new NAS, and restore the data from backup.  That is explained in the kb article: https://kb.netgear.com/29876/ReadyNAS-Migrating-disks-from-RAIDiator-4-1-or-RAIDiator-5-3-to-ReadyNA...

 

The architectures are very different - the file system is BTRFS, not EXT, the RAID is software-based (in your NV+ v1 it's hardware accelerated), the linux is of course current.

Re: RND4210 v1 wont power on

Hi Stephen-

 

Sorry I wasn't clear.  I have a 214 today that is now fully populated with the 4 drives from my old NAS.  In the future at some point I may need to add more storage as right now they are just 4x2TB drives.  I asked the tech if I could buy a 316 and simply move the 4 drives over to the 316 from the 214, add the two additional 2TB drives, and expand the volume.  This would save me from having to buy 4 new drives and replace them one at a time on the 214.  He told me that this isn't possible since the 200 series are consumer grade while the 300+ series are meant for small businesses and use a different architecture. I'd have to do the same process, evacuate all data off the 214 to a different location, move the 4 drives and add two more to the 316, and move it back.  I just wanted to see if this was accurate or not.

He's wrong on that.  You can migrate the drives - the RN316 will install the x86 OS (instead of arm), and will retain your data and settings.

 

Uninstall your apps first!  Many are arm/x86 specific, and they won't migrate.

 

It is of course always good to have a current backup when you are manipulating drives.

Re: RND4210 v1 wont power on

That's good to know.  I got the 214 at Frys price matched to Amazon for $300.  The 316 on Amazon is $500.  That plus two more drives would cost me $340 more after I return the 214 to Frys.  It'd bring my total usable to right under 10TB, almost double the space from what I have now.  4x4TB drives in the 214 would be a little bit higher usable ( around 1TB or so ) but would cost me nearly $600, almost double, since I'd have to buy 4 new drives at double the capacity.

 

Still waiting for tier 3 to call me back.

Re: RND4210 v1 wont power on

Nothing back yet from Level 3. I called in yesterday and was promised a call back by COB.  Nothing.  Called in again this morning and was told they would escaate to the manager but could not guarantee a call back.  So far I'm not thrilled considering I'm paying for this 😕

Re: RND4210 v1 wont power on

Well, to say I am disappointed would be a stretch.  So far no one has called me back.  They keep telling me they have no way to reach Level 3 outside of e-mail and refuse to do anything even though they've e-mailed twice already.  He assured me that they have no possible way to call anyone in level 3 on any of their teams throughout the world......think about that for a second.

 

They keep stating data recovery has a 96 hour return time but they don't seem to be able to tell me when that timer state.  I spoke to a Level 2 supervisor named Stefan who told me data recovery is a low priority item and the 96 hour timer is between responses.  When I pointed out to him that had already passed he didn't seem to care that they violated their own SLA and said he'd just send an e-mail, which is the third time I've had them do that.  They just seem to ignore them.  I told Stefan I'd call him back the same time tomorrow to have him send another e-mail.

 

At this point I am debating on whether or not I just want to mount the drives in a BSD machine and copy the data off myself......any ideas here?

Re: RND4210 v1 wont power on

I found a link to walk you through how to do this but I had to look it up off the internet archive since the original URL seems to be dead:

 

https://web.archive.org/web/20161212021940/http://home.bott.ca/webserver/?p=306

 

Do you have any experience with this?  It seems pretty straight forward and I am confident with Linux.

What I did was calculate the amount of sectors by diving the array size by 512.  I then set a sector system variable and passed it through to create a new PV at the proper size.  Since it was the same data, I had to filter out the wrong UUID in lvm.conf and then try to mount it at which point it mounted fine and I was able to see the filesystem.

 

I ran into one more problem as I was using CentOS for this.  The fuseext2 module is *very* old and no longer maintained.  I would start to copy files and it would fail and dismount the filesystem 20-50 files in.  I had to switch to Ubuntu and use their updated module ( 0.3.1 vs 0.8.1 ) which worked fine to copy all the files off.
