Help needed with Readynas212
Hi! I received an alert my volume was degraded (Disk #2). It then told me: Detected increasing reallocated sector count: [606] on disk 2 (Internal) [WDC WD60EFRX-68L0BN1 WD-WX21D5533R6R] 32 times in...

thanks StephenB and MikeD1234 . So now I've backed up the data from my 6TB to the new 10TB drive. Can someone please walk me through the next steps?
Just to be clear, I am assuming that you connected the 10 TB drive to a PC (windows or mac), and backed up the data on the NAS over the network. If you didn't do that, let us know the details, as the steps below might not be correct.
(a) hot-insert the blank 10 TB drive into the NAS, and wait for it to sync.
If the sync is successful, then
(b) remove the 6 TB drive. Hot-insert the other 10 TB drive and format it in the NAS. It will resync and expand the volume to 10 TB.
if the sync fails, then
(c) remove the 6 TB drive and do a factory default with the blank 10 TB drive in place
(d) reconfigure the NAS (recreating shares etc)
(e) copy the files from your current 10 TB drive
(f) hot-insert the current 10 TB drive into the NAS, select it, and format it. It will then sync with the first drive.
Note if you like, you can skip (a) and (b), and instead just do steps (c)-(f). More work, but you would get a completely clean volume and OS partition.

Once I get my 2nd 10TB drive, do I just take out the 6TB, and insert both 10TB (one has my data, and the other would be the new blank one)?
No, that won't work. So don't try that.
Hi ummjay,
From the sounds of it, you weren't running x-raid (where it chooses the best RAID for you), but instead, ran it in RAID0, or, unless disk #1, already was offline, pulling disk #2, then caused the volume to become inaccessible.
If you want, send me a private message, with a link to your log files, I am happy to have a look at it, and see what is wrong, and what can be done about it.

MikeD1234 If he was using RAID0, the loss of a drive would not have caused the volume to be degraded, it would have been dead. While he said that it said the degraded volume was due to drive 2, maybe it really was drive 1 that caused the NAS to become degraded and the warnings about drive 2 are on top of that. The logs will be of help there.
ummjay Did you inadvertently pull drive 1 and then return it, with power on, during the process of removing drive 2? With power off, please try pulling Drive 1 and putting Drive 2 back in (in bay 2) and then power up and see what you get. If your volume is then accessible, you need to back up your files ASAP. DO NOT add a drive 1, as that will kick of a sync, which is very intensive on both drives, and may cause drive 2 to completely fail.
Sandshark been a while since I worked on RN units.
But, yes, that's what I meant, if he was already experiencing issues with the disk that was still "active", and he ejected it or the wrong one.. We don't really know unless we see the logs, and check how the volume was created, and, what the BTRFS logs say...
Probably not raid0 though, most likely raid1, with two broken disks..
Maybe he can get it up in RO, if one disk is still fine, or, at least readable.
If you can share your logs ummjay.

I took the right disc out, and my data was not accessible. I then put my right disc back in, and that was an issue... I guess I misread the above, as it started to sync. Once I noticed that, I quickly shut down the unit. I then took out the left disc, and put the right back in, and turned back on.
using that drive, on my network I don't see the name of my drive, but instead see: "NAS-B7-B7-5E", with no shares/folders. I try and log in to the admin page via a browser, and my standard login/password doesnt work.
This is a not a good sign, seems like this drive might have no data on it?
update, i put my left disc in, and took the right disc out, and I can access my data..
So i'm going to shut down my NAS now..I ordered a new drive, which should be here in a few days. So the 1 have on the left disc, is a 6TB, and the new one I ordered is a 10tb, shouldnt be an issue they aren't the same capacity in size right? Also, what should I do once I get the new drive, put it on the right, and let it sync from left to right?
Hi ummjay,
For StephenB / Sandshark and myself to give you a good answer, it would be good to see the full logs, so we can actually see what was happening before getting to this point.
It might be, that both disks are faulty, and, even though it only said disk2, disk1 also had issues, this seems the most logical of all situations from what we read.
Further, if you can access your data using the other disk, do you have space to store your data somewhere?
It might be better, to download your data ASAP, once it's downloaded, then, insert the two disks, factory default the NAS, and once the NAS is rebuild after FD, move the data back on the NAS.
Because a sync is very intensive on both disks, it might be that you still run into an issue, whereas, once you have the data backed up, then, you can safely insert the new disk.
Additionally, it's better to have disks of equal size, as you'll loose some space, if the other disk isn't 10TB. As you mentioned the other disk isn't.
So, what you can do, is insert the disk that's still "working", then, boot the volume read-only:
https://kb.netgear.com/22892/How-do-I-access-the-boot-menu-on-my-ReadyNAS-102-202-212-or-312
Once it's in read-only, it won't do any writes to said volume, and allow you to take the data off of the NAS.
Maybe StephenB / Sandshark would like to weigh in here, but I think this would be the safest way forward.
