Yes, but if you have just the 4 disks installed in a new model if a problem comes up with just one of the disks then it could potentially lead to all your data being unrecoverable.
The Pro Pioneer used a 1.8Ghz E2160. The RN300 uses a 2.13 GHz Intel D2700. You can find processor comparisons if you look - the E2160 is faster (passmark score about 1000, the D2700's score is about 850), but the E2160 also uses a lot more power.
If you only look at CPU passmark scores, they rank as follows:
RN516 (~3700 passmark)
ReadyNAS Pro 2nd generation - includes Ultra-6 plus (~1500 passmark)
-I wouldn't go used just to get 150 pathmark points.
-Assuming your disks are intact, the fastest way forward is to migrate your data to a 1st or 2nd generation pro-6. All you need to do is update fhe firmware on the target NAS, power down, and migrate the disks. If you can find one for $300, that is also the least expensive way forward.
The short term risk is mainly that you might be purchasing someone else's problem.
Longer term, of course a used Pioneer is old, so I'd expect it will fail before a new NAS. So if you go this route, you probably should budget/purchase a newer NAS at some point. Then re-purpose the used Pioneer for backup. When it fails, either upgrade the primary NAS again, or pick up another inexpensive backup.
You will need support's assistance to migrate your data to the RN316. You will also need a temporary place to put it - the RN316 will need to reformat the disks.
So contact support before you try inserting the disks.
Assuming the array from the Pro Pioneer is good you should do this:
1. Insert a scratch disk (must not be from your Pro Pioneer) 2. Update the firmware on the 316 to the latest 3. Verify the firmware update was successful
4. Power down and remove the scratch disk
5. Move the disks across (keep the order the same)
6. Power the NAS on NORMALLY.
If all goes well it should boot into 4.2.x and you should be able to access Frontview (note there will be some enclosure errors but you can ignore these) and your data and copy your data off. If not, then contact support. Do not attempt to do other things as that will likely only succeed in making data recovery more difficult.
For half the price you could have just bought another pro 6 unit (in normal circumstances they last a long time even with 24/7 operation), moved your drives over, then updated to OS 6 if you wanted to.
The only time I'd spend good money on a box that isn't an arm based one running os 6 is if I was getting a 12 bay 4220X with 10gbps nics in it...
Initally it would not power on. I unplugged the power cable, plug it back in again, and then tried to turn on at back switch and front button. Tried this like 20 - 30times and then suddendly it will power up. Weirdly after that, no issue with powering up again. I found you HAD to remove the power cable each time. Once i got it powered on it failed to boot it was stuck on readynas logo. Restarted a load more times and suddenly it worked. Backed everything up - and now unit in bin! QNAP TS-253 Pro here I come 🙂
I got the 316 yesterday and immediately proceeded to recover my data following your steps.
Inserted a spare disk and updated the firmware to 6.4, no problems.
Powered the 316 down and moved the disks over from the Pioneer in the same numbered order.
powered it up and it booted into 4.2.27.
Now I´m able to see all my share folders that were on the Pioneer via Raidar-browse, but they are all inaccesible:-(
errorcode 0x80070035.
The only share folder that I can access is the Admin folder, but that shows up as empty.
There has been some enclosure errors as You said.
One is fan failure that is on the front display ans pops up in frontview with intervals.
Another one more disturbing one is "no data volume" that showed up pretty early and with red lights on some of the front leds.
I noticed in Frontview that it was resyncing 2 of the drives, so I left it on when going to work.
Finished now with the resync and rebuild volume, but I´m still stuck with all the shares being inaccesible.
The "no data volume" didn´t show up again after resync.
Under volume settings in Frontview all the disks are ok with a green dot and ok status.
Funny thing is the disk space usage now is 100% and raid configuration is Raid Level 6, 6 disks.
I am sure that the disk usage on the Pioneer was no more then 85%, and it was configured with Xraid2 (dual redundancy), not Raid6.
I have rebooted the unit a few times and changed the password, apart form that no changes made in Frontview as I am uncertain if any intervention on my part would destroy the array
So status right now is that the 316 is on and connectable from Raidar.
There are 2 red leds on the front on disk 1 and 3 ( the same ones that were resynced)
And all my share folders are there, but I can´t acces any of them:-(
So now what to do?
Would it be advisable to power down and reboot without disks 1 and 3, or is that too risky?
Wow... I'm sorry to say this but I saw this train wreck coming a mile away.
The advice should have been, buy another 6 bay unit running 4.x, backup data, upgrade to 6.x on that unit, then buy 316 (if necessary) and migrate to that, then sell the other unit. Seems unnecessary but at least the data would have been there and safe. And yes I'm sure someone will be able to get his data off/back but still this is a perfect example of why not blinding trusting a company when they tell you to buy new over used, capable and much cheaper options.
I've got an ultra that I can downgrade back to 4.x that I'm going to sell. It's in perfect working condition and comes with the non push button drive trays.
You end up copying the data off the array anyways. I think an all around better solution would have been to buy another legacy unit and go from there. You could back it up, migrate to 6 and then use it until the need arises that you have to update hardware (or you could just stay on 4.x if it worked fine for you.) Who knows when they'll come out with new units to replace the current lineup.
The advice should have been, buy another 6 bay unit running 4.x, backup data, upgrade to 6.x on that unit, then buy 316 (if necessary) and migrate to that, then sell the other unit.
Actually I did offer that advice earlier on the thread.
Assuming your disks are intact, the fastest way forward is to migrate your data to a 1st or 2nd generation pro-6...
It still is an option of course. But the RN316 does have 90 phone support, so I think at this point OP should start there.
I was considering that as well, but decided to go for the new unit thinking I could recover my data that way.
Now that has proven problematic, I´m hoping I can still go the used Pioneer route.
But is there any chance that will still work?
I´m a bit worried by the errors I have on the 316 with the old disks, so is there anything the 316 could have done to the array that has now rendered it unreadable in a "new" second hand Pro Pioneer??
I can return the 316 within 14 days, so have 12 days left for "magic to happen".
If I buy a used Pro Pioneer, there´s no return option so I would like to know there´s a reasonable chance of succes before I do just that.
