ReadyNas 212 HELP needed
Hello all, I have a Readynas 212 and I need help after making many errors. I currently have 2x 4TB drives. Drive #1 is older and had data already. I turned from JBOD to RAID1 by moving for X-RAID...

First, don't bother with tailed drive. Boot up the system with only the 4 TB drive in place.
If you are still using password as the NAS admin password, then change that to something. Then double-check that ssh is still enabled in system->settings->services->ssh.
You can then download WinSCP ( https://winscp.net/eng/index.php ). That supports a protocol called SFTP. Set up a connection that uses that protocol.
Use the IP address of your Nas (not the one in the screen shot).
After you connect, the right pane should look something like this:
Somewhere in that list you should see your DSK-4TB folder. Navigate into it, and see if your shares are listed. If they are, you can copy them to a disk on the PC.

All right, 6TB is backed up now.
The count of disks is like this now:
#1 - 4TB OLD: This one is the one you mentioned started failing since 2023 with reallocated and pending sectors.This one used to be in the Flex-Raid with disk #2 (Could have the data pending to backup). NAS would not boot with this drive alone. When booting with disk #2, this disk would not be recognized correctly and power light would blink slowly constantly.
#2 - 4TB New1: This one has the data still pending to back up but files do not show when browsing via admin page.
NAS can boot with this drive alone.
It should have the same data than #1, but no data is available.
This is all that shows when browsing this disk:
#3 - 6TB: This disk has been backed up already. This is the "data" volume (JBOD) and it boots correctly.
#4 - 4TB New2: This disk has all the data backed up from "#3 - 6TB". (1.6TB of data backed up)
This disk has been formatted in windows.
Now, StephenB, is there anything that can be done to try to recover the data on either 4TB #1 or #2?
Once data is backed up from either #1 or #2, I would like to make a step by step of how to make this right and have a 4TB with redundancy NAS.
Thank you as always for your help and patience!

Unfortunately I can't enable SSH:
Same issue has been happening when tried to enable DLNA.

Booting both allowed to enable SSH.
Looks like I've connected via SSH with WinSCP and nothing is showing up:
Both folders there are completely blank. I logged in using the admin user and the "martin" user as well. Same result in both cases.

Are you in the DSK-4TB folder? It looks like you might instead be in the home folder.
Try clicking on the top folder icon (..) to bring you up a level. When you get to <root> at the top, you should see DSK-4TB in the folder list.

Stephen, you are my savior! I'm backing all the data from the 4TB disk that was missing.
Once this is backed up I plan to format everything and start again but the back up disk is one of the new 4TBs (Windows formatted). So would be be sound to do this?
- Format via admin page with disks #1 (old and somewhat faulty 4TB disk) and #2 (first new 4TB disk) both in the NAS.
- Set up a redundancy config with X-RAID (RAID1).
- Move files back from backup to this new X-RAID.
- Keep 6TB as backup for when 4TB Old disk completely fails. In that case it would be just a matter of removing the faulty one and insterting the replacement one?
Meanwhile keep the 2nd 4TB disk as spare back up just in case all goes to hell again.
Or should I format them individually, use the newest one as JBOD, move all the backed up data over network and then add the back up disk to sync up?
Again, thank you VERY much StephenB, you saved me!

Disk 1 is not "somewhat faulty". It has failed, and shouldn't be used at all.
What you should do is put in disk 2 and the new 4 TB drive, and then do a factory default. You can do this from the boot menu when you power up, or you can do it from system->settings->update in the admin web ui. (If the system is syncing the new disk, you don't need to wait for it to finish - you can do the factory default right away).
Then reconfigure your NAS settings while the RAID sync is going on (re-creating shares, and other settings). When the sync finishes, restore your data from your backups.
As far as the 6 TB drive goes, if you want to access it in the future, you would
- power down the NAS
- remove both 4 TB drives
- insert the 6 TB drive by itself
- power up
Though personally, after the 2x4TB setup is completely operational I either get a USB enclosure for it or install it in a PC. Then reformat it as NTFS, and use it as part of my backup plan (running backups on schedule using the NAS backup job facility).

So let's scratch the old 4TB off the list of disks.
Yes, I plan on occasionally using one drive via USB to the PC. That could be the 6TB disk and have the 2 NEW 4TB as NAS. Problem is: I have backed up the data into one of the NEW 4TB disks...
If I insert both 4TB disks to NAS and follow those stepf for Factory reset, wouldn't that eliminate the data on those inserted disks like a format would?

Your best bet is to set up what you intend to use as a backup system and put the backup files on it before doing what StephenB suggested. The following alternative will work, but your data will be at risk without a backup:
- Do a factory default with just the 4TB without the backup data and create a JBOD volume.
- Copy the data from the backup to the NAS.
- Add the 4TB to the NAS and FORMAT it. This destroys your backup, so you're without one unless you create a new method. XRAID will then add the second 4TB to the volume in RAID1.

Ihshinron - In step one, just stay with X-RAID and keep the default volume. No need to switch to FlexRAID.

Sounds linke a plan, what I could do is:
- Do a factory default with just the 4TB without the backup data and create a JBOD volume.
- Copy the data from the backup to the NAS.
- Format 6TB in windows.
- Connect 6TB via USB to NAS as external drive and copy all the backed up data.
- Add the 2nd 4TB (with original backup to the NAS) and FORMAT it. This destroys your backup, so you're without one unless you create a new method. XRAID will then add the second 4TB to the volume in RAID1.
Will stay away from Flex Raid. But what do I need to do in step 5 after inserting the 2nd 4TB disk to change from JBOD to RAID1 correctly? I guess it would be first format that new disk and then turn to RAID1?
Thank you both

- Configure the NAS - creating shares etc
- Copy the data from the 4 TB backup to the NAS shares
- Format the 6 TB drive and copy the data to it. Set up automated backup (on a schedule)
- hot-insert the 2nd 4TB (with original backup to the NAS) and FORMAT it. XRAID will then add the second 4TB to the volume (converting it to RAID-1).
There are a couple of options with (4).
- You can do your backups with the drive connected to your Windows PC. FreeFileSync is one of several tools that can automate that (doing it on a schedule). This works well if the PC is a desktop (or perhaps a laptop that you never move).
- You can also connect the disk to the NAS and create one or more NAS backup jobs to update the backup on a schedule. I generally create one backup job per share.
Either way, you need to keep an eye on the backup status, and make sure it is running correctly. I am guessing that might be easier for you if you connect the drive to a Windows PC. But both approaches are used by people here.

Is it wrong to create 1 new share where all docs, videos and music will be stored and then shared with user access?It's not wrong.
That said, If you have multiple users and want to limit access for some of those users (children for example), then it's much easier to put the restricted files into a different share from the rest.
Buf if you don't need to limit access for some users, then can you certainly put everything into one share if you wish.

Thank you very much Stephen, I'll let you know when I've finished doing all this. Right now I've formatted one of the 4TB, I'm transferring data into it little by little and then more to come.
Again, thank you for your help and patience!!
- IhshinronApr 30, 2025Aspirant
Ok, so I've factory resetted everything with one of the 2 4TB disks. Then moved everything over the network. Then backed that data in the 6TB disk just in case. This is the "data" volume in JBOD.
Now, the original back up disk (the 2nd brand new 4TB disk) was hot-inserted into the NAS and this is the screen I see:
It recognizes the volume already created on that 2nd disk (the one on the right). So what I should do now would be to select that Exter-4TB and hit the "format" button?
From there it will format it (would it ask to remove the disk in slot 1 for security?) and then add it as RAID1 automatically or should I do something else after formatting?
StephenB I'll wait for your response to be sure I'm doing the right thing.
Thank you once more.

Select the disk in the center pane, and then format it on the right. That should automatically add it to the RAID array.

OK, I've done that nad it started Resyncing process but it shows a message up top stating "Volume data health changed from Unprotected to Degraded".
Would that go away (back to "healthy")once it finishes resyncing?

That is normal during a sync, and it will change when the sync finishes.
